Abstract
INTRODUCTION Angioinvasive fungal sinusitis (AIFS) is a rapidly progressive, highly morbid infection. It can be challenging to obtain an early diagnosis, but intervention in the acute period is crucial for prognosis. Previous literature has identified numerous radiographic features with high sensitivity and specificity for AIFS, even in early disease. Bedside nasal endoscopy can substantiate the diagnosis but can also yield false negative results. Initially, these patients may present to the ophthalmologist. Thus, to avoid visual and potentially life-threatening complications, subtle clinical signs in conjunction with suspicious radiographic features must be promptly recognized by the ophthalmologist and escalated appropriately. We review, for the benefit of the ophthalmic community, the salient radiographic features of AIFS and integrate them into a decision-making algorithm for diagnostic workup and management. METHODS A literature search was conducted using a comprehensive keyword search in the Pubmed and Embase databases. English studies from 1988 to 2022 describing the radiographic features of AIFS queried. Literature on the newly described entity, COVID-19 COVID-19-associated mucormycosis was included. The authors collected the most frequently reported indicators of AIFS. RESULTS The authors review 4 radiographic findings that are frequently associated with AIFS, including in the early stages of disease: 1) loss of contrast enhancement in the nasal turbinate and maxilla (i.e., "black turbinate and maxillary sign"), (2) periantral involvement seen as changes in density, fat stranding or obliteration of the anterior, retromaxillary, or retroantral fat planes on CT, (3) Tissue invasion without bony erosion, (4) Hypointense T2W sinonasal secretions on MRI in the setting of acute sinusitis. The authors additionally propose an algorithm that suggests surgical exploration for patients with clinical concern for AIFS and these radiographic features, even if bedside nasal endoscopy is inconsistent with AIFS. CONCLUSION The radiographic signs highlighted herein should heighten suspicion for AIFS in the appropriate clinical setting, prompting urgent surgical exploration regardless of nasal endoscopy findings.

Abstract
Non-traumatic head and neck emergencies include several disease processes such as infectious, inflammatory, and malignant. Infections are among the most common pathological processes that affect the head and neck, and are particularly important due to their acute, severe, and potentially life-threatening nature. Radiologists need to be well acquainted with these entities because any delay or misdiagnosis can lead to significant morbidity and mortality. Having a general understanding of such diseases is crucial, their prevalence, clinical presentation, common causative pathogens, route of spread, potential complications, and multimodality radiological appearance. Furthermore, understanding the relevant anatomy of the region, including the various fascial planes and spaces, is essential for radiologists for accurate image interpretation and assessment of potential complications. Our aim is to review the most common severe infections affecting the head and neck as well as other rare but potentially life-threatening infections. We will also describe their imaging features while focusing on the anatomy of the regions involved and describing their potential complications and treatment options.

Abstract
Fungal rhinosinusitis (FRS) includes non-invasive and invasive subtypes with the latter having significant morbidity and mortality. This systematic review aims to identify the imaging features most correlated with invasive fungal rhinosinusitis (IFRS) and present a checklist of these features to aid diagnosis. PubMed, Embase, CENTRAL, and Science Direct were searched from inception to May 2023, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Primary research articles published in English describing the imaging features of IFRS were included. The systematic review was conducted in accordance with the PRISMA guidelines. Forty-eight articles were identified for inclusion. Six studies examined radiological features in acute invasive fungal rhinosinusitis (AIFRS), and 9 studies of chronic invasive fungal rhinosinusitis (CIFRS). A majority of studies did not specify whether IFRS cases were acute or chronic. On CT, bony erosion and mucosal thickening were the most common features. Other features include nasal soft tissue thickening, nasal cavity opacification, opacification of the affected sinus, and perisinus soft tissue infiltration. Extra-sinus extension was commonly observed on MRI, most often invading intraorbitally and intracranially. Other sites of extra-sinus extension included the cavernous sinus, pterygopalatine fossa, infratemporal fossa, masticator space, and facial soft tissue. IFRS is a condition with potential for high morbidity and mortality. Several radiological features are highly suggestive of IFRS. Early identification of high-risk radiological features using a checklist may aid prompt diagnosis and early treatment. Future research investigating the radiological differentiation between IFRS and other significant pathology including bacterial orbital cellulitis would be beneficial.

Abstract
This is a retrospective study exploring the demographics and the role of nasal septum deviation in acute invasive fungal rhinosinusitis (AIFS); and if this deviation contributes to the laterality predilection of this opportunistic infection. Fifty-six craniofacial CT scans were evaluated by two radiologists blinded to the clinical data and outcome for laterality of the disease; and nasal septal deviation (NSD). NSD was graded based on the measured septal angle of deviation into mild, moderate, and severe and furtherly classified into one of seven types based on Mladina's classification. High prevalence of remarkable nasal septum deviation existed in our population with AIFS, with type 7 Mldina NSD represented the most prevalent in this population. We found no significant statistical relation between the side of deviation and the initial side of the fungal disease. We recommend screening for early manifestations of AIFS in similar debilitated patients; with high degrees of nasal septum deviation for considering it as an anatomical risk factor.

Abstract
PURPOSE OF REVIEW To summarize the evidence surrounding diagnosis, treatment, prognosis, and surveillance of patients with acute invasive fungal sinusitis (AIFS) and discuss future research needs. RECENT FINDINGS New risk factors for AIFS such as COVID have been identified, and a new prognostic staging system has been developed. SUMMARY Most patients who develop AIFS are immunocompromised, with the majority having a history of diabetes or a hematologic malignancy. Unfortunately, there are not any highly sensitive and specific diagnostic tools. Therefore, a combination of signs and symptoms, imaging, endoscopy, biopsy, and labs should be used to diagnosis AIFS. Although surgery and systemic antifungals are known to improve outcomes, there is limited data on time to intervention, duration of antifungals, and surveillance patterns. There is also limited information on factors that can predict outcomes in AIFS patients. However, sensory/perceptual changes, prolonged neutropenia duration, and comorbidity burden may be associated with a poor prognosis.

Abstract
PURPOSE Invasive fungal orbital infections (IFOI) may be difficult to differentiate from sinogenic bacterial orbital cellulitis (OC). This study investigates the features differentiating OC from IFOI on magnetic resonance imaging (MRI). METHODS Retrospective study of adult patients with sinogenic OC and IFOI with pre-intervention MRI. Patients without post-septal involvement, non-sinogenic OC (e.g.: secondary to trauma) and poor-quality scans were excluded. Independent Sample's t test and Fisher's exact test were conducted with p < 0.05 deemed statistically significant. RESULTS Eleven cases each of OC (Mean age: 41.6 ± 18.4 years-old, Male: 10) and IFOI (Mean age: 65.0 ± 16.6 years-old, Male: 9) between 2006 and 2023. IFOI patients were older, more likely immunocompromised and had a lower mean white-cell count (p value = 0.005, 0.035 and 0.017, respectively). The ethmoid and maxillary sinuses were most commonly involved in both entities. Pre-septal and lacrimal gland involvement were more common in OC (p = 0.001 and 0.008, respectively). Infiltrative OC orbital lesions were poorly demarcated, whilst those in IFOI were expansile/mass-like invading the orbit from the adjacent paranasal sinuses. Specific IFOI features included loss-of-contrast-enhancement (LoCE) of paranasal sinus tissues with orbital extension. Extra-orbital and -sinonasal extension indicative of IFOI included contiguous skull base or pterygopalatine fossa involvement, retro-antral and masticator space stranding and vasculitis. CONCLUSION This study describes the key MRI features of IFOI including differentiating markers from OC. These specific features, such as LoCE of the paranasal and orbital soft tissues, the location and pattern of contiguous soft-tissue involvement, provide expedient identification of IFOI which necessitate early surgical intervention for microbiological confirmation of an invasive fungal pathology.

Abstract
BACKGROUND Imaging is a key diagnostic modality for suspected invasive pulmonary or sinus fungal disease and may help to direct testing and treatment. Fungal diagnostic guidelines have been developed and emphasize the role of imaging in this setting. We review and summarize evidence regarding imaging for fungal pulmonary and sinus disease (in particular invasive aspergillosis, mucormycosis and pneumocystosis) in immunocompromised patients. OBJECTIVES We reviewed data on imaging modalities and findings used for diagnosis of invasive fungal pulmonary and sinus disease. SOURCES References for this review were identified by searches of PubMed, Google Scholar, Embase and Web of Science through 1 April 1 2023. CONTENT Computed tomography imaging is the method of choice for the evaluation of suspected lung or sinus fungal disease. Although no computed tomography radiologic pattern is pathognomonic of pulmonary invasive fungal disease (IFD) the halo sign firstly suggests an angio-invasive pulmonary aspergillosis while the Reversed Halo Sign is more suggestive of pulmonary mucormycosis in an appropriate clinical setting. The air crescent sign is uncommon, occurring in the later stages of invasive aspergillosis in neutropenic patients. In contrast, new cavitary lesions should suggest IFD in moderately immunocompromised patients. Regarding sinus site, bony erosion, peri-antral fat or septal ulceration are reasonably predictive of IFD. IMPLICATIONS Imaging assessment of the lung and sinuses is an important component of the diagnostic work-up and management of IFD in immunocompromised patients. However, radiological features signs have sensitivity and specificity that often vary according to underlying disease states. Periodic review of imaging studies and diagnostic guidelines characterizing imaging findings may help clinicians to consider fungal infections in clinical care thereby leading to an earlier confirmation and treatment of IFD.

Abstract
Acute invasive fungal sinusitis (AIFS) is a fungal infection of the nasal cavity and paranasal sinuses with associated invasion of adjacent vessels and soft/hard tissues. It usually occurs in immunocompromised patients and may follow a rapid course of less than four weeks with high mortality rate. We report a 39-year-old male with relapse of acute myelogenous leukemia (AML) who was under evaluation for neutropenic fever. On his sinus CT, there was loss of calcification of his nasal septum when compared to a prior head CT, a sign indicative of an aggressive infectious process. He was diagnosed with AIFS and underwent emergent surgical debridement and systemic antifungal therapy, leading to a positive outcome. The sign described on CT ("Vanishing Nasal Septum" sign) may provide an additional, reliable tool to prospectively identify locally aggressive cases of invasive fungal infections of the nasal cavity at an earlier stage and improve patient outcomes.

Abstract
Odontogenic and sinogenic infections are frequently encountered in the pediatric population. Although the diagnosis is often suspected clinically, imaging can play a significant role in localizing the site of infection, assessing for involvement of deep neck spaces, detection of abscess and other potentially life-threatening complications, and providing valuable information to help with treatment planning. This article reviews the general imaging considerations and anatomy relevant to odontogenic and paranasal sinus infections and describes the salient clinical and imaging features of infectious diseases of the dentition and sinuss.

Abstract
BACKGROUND Acute invasive fungal sinusitis (AIFS) is an aggressive disease that requires prompt diagnosis and multidisciplinary treatment given its rapid progression. However, there is currently no consensus on diagnosis, prognosis, and management strategies for AIFS, with multiple modalities routinely employed. The purpose of this multi-institutional and multidisciplinary evidence-based review with recommendations (EBRR) is to thoroughly review the literature on AIFS, summarize the existing evidence, and provide recommendations on the management of AIFS. METHODS The PubMed, EMBASE, and Cochrane databases were systematically reviewed from inception through January 2022. Studies evaluating management for orbital, non-sinonasal head and neck, and intracranial manifestations of AIFS were included. An iterative review process was utilized in accordance with EBRR guidelines. Levels of evidence and recommendations on management principles for AIFS were generated. RESULTS A review and evaluation of published literature was performed on 12 topics surrounding AIFS (signs and symptoms, laboratory and microbiology diagnostics, endoscopy, imaging, pathology, surgery, medical therapy, management of extrasinus extension, reversing immunosuppression, and outcomes and survival). The aggregate quality of evidence was varied across reviewed domains. CONCLUSION Based on the currently available evidence, judicious utilization of a combination of history and physical examination, laboratory and histopathologic techniques, and endoscopy provide the cornerstone for accurate diagnosis of AIFS. In addition, AIFS is optimally managed by a multidisciplinary team via a combination of surgery (including resection whenever possible), antifungal therapy, and correcting sources of immunosuppression. Higher quality (i.e., prospective) studies are needed to better define the roles of each modality and determine diagnosis and treatment algorithms.

Abstract
Aim We aim to study the spectrum of imaging findings in patients with rhino-oculo-cerebral mucormycosis (ROCM). Materials and methods This retrospective descriptive study was performed in histopathologically confirmed cases of rhino-oculo-cerebral mucormycosis in a tertiary care center in Bihar, India. The case records of patients with radiological, cultural, and histological evidence of acute invasive ROCM were retrospectively evaluated for relevant radiological and clinical data between May 2021 and June 2022. Results The radiological evaluation included computed tomography (CT) and magnetic resonance imaging (MRI) scans done on 52 patients. The patient's average age was 48 years. The ethmoid sinus was involved in 51 (98%) cases and the maxillary sinus in 50 (96%) cases. Bilateral sinus involvement (45, 86%) was the most common, followed by pansinus involvement (27, 52%). The orbit was involved in 39 (75%) cases, the face in 25 (47%) cases, and retroantral fat stranding in 24 (46%) cases. Mucosal thickening (91%) was the most common pattern of involvement, followed by complete opacification (77%). Osseous involvement was seen in 17 of 44 patients who had CT scans, and the majority of patients had extrasinus extension with intact bone. MRI revealed variable T2SI, with T2 hyperintensity being the most common pattern. Heterogeneous enhancement in post-contrast imaging was the most common. Conclusion ROCM is a life-threatening invasive fungal infection, especially in an immunocompromised state. ROCM is characterized by a variety of imaging abnormalities on CT and MRI, although nonspecific. Imaging aids in suspicion or early diagnosis in appropriate clinical contexts, particularly in an immunocompromised state, and in determining the degree of involvement and complications. Early detection of ROCM and its complications enables proper treatment, which can lower the cost of care, morbidity, and mortality.

Alabdullah MN, Yousfan A. Is low dose of liposomal amphotericin B effective in management of acute invasive fungal rhinosinusitis? Our conclusions from Al-Mowassat University Hospital, Syria: a prospective observational study. BMC Infect Dis 2023; 23:196. [PMID: 37004006 PMCID: PMC10064616 DOI: 10.1186/s12879-023-08177-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Accepted: 03/17/2023] [Indexed: 04/03/2023] Open
Abstract
BACKGROUND Acute invasive fungal rhinosinusitis (AIFRS) is a fatal infection associated with high morbidity and mortality. Although it is a rare disease, upsurge of AIFRS was noticed during the second wave of COVID-19 disease. Early diagnosis and management is the cornerstone for good outcomes. However, management of AIFRS is challengeable especially in developing countries due to limited resources and high prices of antifungal agents. No previous studies have been conducted to evaluate the outcomes of management of AIFRS in Syria. The purpose of this study is to report the results of management of AIFRS with low doses of liposomal amphotericin B in our tertiary hospital in Syria. METHODS The outcomes of management of AIFRS cases were followed through a prospective observational study between January 2021 and July 2022. The required medical data were collected for each individual. Three-month mortality rate was studied. SPSS v.26 was used to perform the statistical analysis. Pearson Chi-square test was used to study the associations between different variables and mortality. Survival curves were plotted by the Kaplan-Meier to compare the survival probability. Log Rank (Mantel-Cox) test and Cox regression were conducted to evaluate the factors affecting survival within the follow up period. RESULTS Of 70 cases, 36 (51.4%) were males and 34 (48.6%) were females. The mean age of patients was 52.5 years old. The most common underlying risk factor was diabetes mellitus (84.3%). The used dose of liposomal amphotericin B ranged between 2-3 mg/kg per day. The overall 3-month mortality rate was 35.7%. Significant association was found between survival and the following variables: Age, orbital involvement, stage, and comorbidity. CONCLUSION The overall mortality rate was close to other studies. However, survival rate was worse than comparable studies in selected cases of AIFRS (older ages, involved orbits, advanced stages, and chronic immunodeficiency). Therefore, low doses of liposomal amphotericin B could be less effective in such cases and high doses are recommended.

Abstract
Rhinocerebral mucormycosis has emerged as a common coinfection in coronavirus disease 2019 (COVID-19) patients during the convalescence period. Frequent spread of disease from sinonasal mucosa to bone, neck spaces, orbit, and brain occurs along the perivascular/perineural routes or through direct invasion. Brain involvement represents severe manifestation and is often associated with poor functional outcomes and high mortality rates. Magnetic resonance imaging (MRI) is the modality of choice for the intracranial assessment of disease severity in mucormycosis. Early and accurate identification of intracranial extension is imperative to improve survival rates. With this pictorial essay, we aim to familiarize the readers with the cross-sectional imaging features of intracranial complications of mucormycosis. The radiological details in this essay should serve as a broad checklist for radiologists and clinicians while dealing with this fulminant infection.

Abstract
COVID-19 pandemic has led to a concerning surge of post-COVID-19 AIFR. Mucormycosis (BLACK fungus) is a rare but severe and life-threatening fungal infection occurred by mucormycetes, a family of moulds. More than 49,000 cases of AIFR were reported in three months in India. It primarily affects diabetics and spreads from the nasal cavity and paranasal sinuses (PNS). It also involves eye, palate, or brain. It is diagnosed clinically followed by radiological and pathological findings. We aimed to compare and analyse the pre-operative imaging with postoperative histopathological findings. The study was conducted in ENT department of tertiary care hospital, Rajkot. 200 patients were randomly selected who were presented to ENT OPD with clinically suspected Post COVID-19 AIFR. All patients underwent detailed ENT examination and radiological modality like MRI PNS, Brain, and Orbit. After proper pre-op evaluation, all patients underwent Functional Endoscopic Sinus Surgery (FESS). MRI findings were confirmed with that of histopathological findings done on KOH mount. All the patients were showing AIFR on MRI findings whereas 49% of patients had mucormycosis on Histopathology. Various other fungal infections like aspergillosis (7%), candidiasis (1.5%) were also found on HPE. 9% of patients showed combined infection with mucor and aspergillus species. Rest of the patients showed non-fungal rhinosinusitis. Inflow of the epidemic, plenty of patients were shown invasive fungal sinusitis in MRI patterns whereas many of them were HPE negative. Thus this study was done to know the efficacy of radiological features with pathological diagnosis. We have considered both procedures standard in our study.

Abstract
PURPOSE OF REVIEW The current article will update and review the clinical and radiological manifestations and management of rhino-orbital mucormycosis (ROM). RECENT FINDINGS There has been an increase in cases of ROM worldwide, especially in India. Immunosuppression (especially diabetes mellitus) is a known predisposing risk factor for ROM. Delayed diagnosis and treatment of ROM can be vision or life-threatening. This article reviews the clinical and radiologic features, treatment, and prognosis of ROM with special emphasis on new and emerging therapies. SUMMARY ROM is an angioinvasive fungal infection that affects the sinuses and orbits and may present to ophthalmologists. Clinicians should have a high index of suspicion for ROM, especially in patients with poorly controlled diabetes mellitus or other immunosuppression. Corticosteroid treatment (including the recent COVID-19 pandemic) may be a predisposing risk factor for ROM.

Abstract
PURPOSE To identify initial, preintervention magnetic resonance imaging (MRI) findings that are predictive of visual and mortality outcomes in acute invasive fungal rhinosinusitis (AIFRS). DESIGN Retrospective cohort study. PARTICIPANTS Patients with histopathologically or microbiologically confirmed AIFRS cared for at a single, tertiary academic institution between January 2000 and February 2020. METHODS A retrospective review of MRI scans and clinical records of patients with confirmed diagnosis of AIFRS was performed. For each radiologic characteristic, a modified Poisson regression with robust standard errors was used to estimate the risk ratio for blindness. A multivariate Cox proportional hazards model was used to study AIFRS-specific risk factors associated with mortality. MAIN OUTCOME MEASURE Identification of initial, preintervention MRI findings associated with visual and mortality outcomes. RESULTS The study comprised 78 patients (93 orbits, 63 with unilateral disease and 15 with bilateral disease) with AIFRS. The leading causes of immunosuppression were hematologic malignancy (38%) and diabetes mellitus (36%). Mucormycota constituted 56% of infections, and Ascomycota constituted 37%. The overall death rate resulting from infection was 38%. Risk factors for poor visual acuity outcomes on initial MRI included involvement of the orbital apex (relative risk [RR], 2.0; 95% confidence interval [CI], 1.1-3.8; P = 0.026) and cerebral arteries (RR, 1.8; 95% CI, 1.3-2.5; P < 0.001). Increased mortality was associated with involvement of the facial soft tissues (hazard ratio [HR], 4.9; 95% CI, 1.3-18.2; P = 0.017), nasolacrimal drainage apparatus (HR, 5.0; 95% CI, 1.5-16.1; P = 0.008), and intracranial space (HR, 3.5; 95% CI, 1.4-8.6; P = 0.006). Orbital soft tissue involvement was associated with decreased mortality (HR, 0.3; 95% CI, 0.1-0.6; P = 0.001). CONCLUSIONS Extrasinonasal involvement in AIFRS typically signals advanced infection with the facial soft tissues most commonly affected. The initial, preintervention MRI is prognostic for a poor visual acuity outcome when orbital apex or cerebral arterial involvement, or both, are present. Facial soft tissues, nasolacrimal drainage apparatus, intracranial involvement, or a combination thereof is associated with increased mortality risk, whereas orbital soft tissue involvement is correlated with a reduced risk of mortality.

Abstract
PURPOSE This case series analyzed the appropriateness of computed tomography (CT) and magnetic resonance imaging (MRI) for visualization of rhinoorbitocerebral mucormycosis (ROCM) patterns associated with type 2 diabetes (T2D) post-recovery from coronavirus disease 2019 (COVID-19). METHODS The study included 24 patients with invasive ROCM after having recovered from COVID-19. All patients underwent CT examinations and microbiological and histological verification; 5 patients underwent MRI. RESULTS The CT and MRI patterns noted in our patients revealed involvement of skull orbits, paranasal sinuses, large arteries, and optic nerves, with intracranial spread and involvement of the cranial base bones. Using brain scan protocol for CT provided better soft-tissue resolution. We found that extending the MRI protocol by T2-sequence with fat suppression or STIR was better for periantral fat and muscle evaluations. CONCLUSION Computed tomography of the paranasal sinuses is the method of choice for suspected fungal infections, particularly mucormycosis. However, MRI is recommended if there is suspicion of orbital, vascular, or intracranial complications, including cavernous sinus extension. The combination of both CT and MRI enables determination of soft tissue invasion and bony destruction, thereby facilitating the choice of an optimal ROCM treatment strategy. Invasive fungal infections are extremely rare in Europe; most of the related data are provided from India and Middle Eastern or African nations. Hence, this study is notable in its use of only diagnosed ROCM cases in Russia.

Abstract
Invasive fungal rhinosinusitis (IFRS) is a serious infection that is associated with high morbidity and mortality rates. The incidence of IFRS has been increasing, mainly because of the increased use of antibiotics and immunosuppressive drugs. Rhino-orbital cerebral mucormycosis has recently reemerged among patients affected by COVID-19 and has become a global concern. The detection of extrasinus involvement in its early stage contributes to improved outcomes; therefore, imaging studies are essential in establishing the degree of involvement and managing the treatment properly, especially in immunocompromised patients. The common sites of extrasinus fungal invasion are the intraorbital, cavernous sinus, and intracranial regions. Fungi spread directly to these regions along the blood vessels or nerves, causing devastating complications such as optic nerve ischemia or compression, optic neuritis or perineuritis, orbital cellulitis, cavernous sinus thrombosis, mycotic aneurysm, vasculitis, internal carotid arterial occlusion, cerebral infarction, cerebritis, and brain abscess. IFRS has a broad imaging spectrum, and familiarity with intra- and extrasinonasal imaging features, such as loss of contrast enhancement of the affected region, which indicates tissue ischemia due to angioinvasion of fungi, and the surrounding anatomy is essential for prompt diagnosis and management. The authors summarize the epidemiology, etiology, risk factors, and complications of IFRS and review the anatomy and key diagnostic imaging features of IFRS beyond the sinonasal regions. ©RSNA, 2022.

Abstract
Background The objective is to describe the radiological imaging findings of post-COVID-19 acute invasive fungal rhinosinusitis (AIFRS), being familiar with the wide variety of imaging spectrum, thus raising the suspicion for early diagnosis. Methods: In this retrospective study, we reviewed the imaging findings in 54 patients with proven post-COVID-19 AIFRS who underwent endoscopic/surgical debridement from April 2020 to September 2021. Most of these patients presented with facial or orbital swelling or facial pain. Medical records with a special emphasis on radiological imaging (50 NCCT of the paranasal sinuses and 17 MRIs of the orbit) were reviewed regarding the degree of mucosal disease of sinuses, nasal cavity, and nasopharynx, extra sinus soft tissue infiltration, especially orbital and cerebral extension (parenchymal, cavernous sinus, vascular or neuro-invasion). Results We reported findings in 54 patients with post-COVID-19 AIFRS, of whom 30 were men and 24 were women with a mean age of 48.06. Unexpectedly, infiltration of pterygopalatine fossa was found to precede mucosal opacification of sinuses nasal cavity and affection of nasopharynx. Out of 54 patients, 49 showed inflammatory changes involving pterygopalatine fossa, 29.6% of patients showed infiltration of orbital tissues, 22 patients suffered from a fungal invasion of the cavernous sinus and 3 patients had carotid artery involvement. Conclusions Imaging findings of AIFRS significantly vary from subtle mucosal thickening of paranasal sinuses, up to orbital and intracranial extension with vascular thrombosis and neuroinvasion. The hallmark inflammatory tissue infiltration into the pterygopalatine fossa and facial soft tissue may precede mucosal disease.

Abstract
PURPOSE To define different risk groups of patients suspected of having acute invasive fungal sinusitis (AIFS) and develop a goal-directed diagnostic approach. MATERIALS AND METHODS Forty patients with suspected AIFS biopsied from 2010 to 2020 were included in this study. Patients diagnosed with chronic invasive fungal sinusitis or without biopsy results were excluded. A recursive partitioning analysis (RPA) model was performed to define patient cohorts with the highest risk of having a positive biopsy for AIFS. RESULTS There were a total of 26 patients with biopsy-proven AIFS. Patient characteristics significantly associated with an increased likelihood of a positive biopsy for AIFS on bivariate analysis included facial pain (p = 0.047), platelet count <50,000 cells/mm3 (p = 0.028), and abnormal CT findings, most commonly, bilateral sinus opacification (p = 0.003). The RPA model identified three risk factors for predicting a patient's probability of having a positive biopsy for AIFS, resulting in four-terminal nodes. In the twenty-six patients who had biopsy-proven AIFS, the post-operative 30-day all-cause mortality was 50 % (13/26) and overall mortality was 88.5 % (23/26). Predictors of 30-day all-cause mortality included prolonged interval between biopsy and operative start time (p = 0.042) and earlier initiation of antifungals prior to the operative start time (p = 0.042). CONCLUSION Our findings indicate that patients with a fever of unknown origin, low platelet count, and/or ANC are at an increased risk of being diagnosed with biopsy-proven AIFS. Using these risk factors, we propose a diagnostic approach that may expedite the treatment of patients with AIFS; however, future prospective studies are needed for validation.

Abstract
The use of magnetic resonance (MR) imaging in the emergency department continues to increase. Although computed tomography is the first-line imaging modality for most head and neck emergencies, MR is superior in some situations and imparts no ionizing radiation. This article provides a symptom-based approach to nontraumatic head and neck pathologic conditions most relevant to emergency head and neck MR imaging, emphasizing relevant anatomy, "do not miss" findings affecting clinical management, and features that may aid differentiation from potential mimics. Essential MR sequences and strategies for obtaining high-quality images when faced with patient motion and other technical challenges are also discussed.

Imaging spectrum of rhino-orbital-cerebral mucormycosis secondary to COVID-19 infection: a reporting checklist. Pol J Radiol 2022; 87:e333-e347. [PMID: 35892068 PMCID: PMC9288200 DOI: 10.5114/pjr.2022.117647] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Accepted: 09/23/2021] [Indexed: 11/17/2022] Open
Abstract
In recent times, India has been in the midst of a notifiable epidemic of mucormycosis (a rare angio-invasive fungal infection), within the ongoing global coronavirus disease 2019 (COVID-19) pandemic. Epidemiological studies have reported the estimated prevalence of mucormycosis to be around 70 times higher in India as compared to the global data, even in the pre-COVID era. However, in the last 3 months, our city witnessed an unprecedented surge in cases of post-COVID-19-associated rhino-orbital-cerebral (ROC) mucormycosis. This pictorial review aims to illustrate the entire imaging spectrum of mucormycosis in the head-neck-face region. Along with the usual sites (nose, paranasal sinuses, orbits), this disease also involves the skull base, palate, temporal bone, and deep neck spaces. Many cases also demonstrated morbid and, at times, fatal intracranial and neurovascular complications. This review also aims to provide a structured reporting template that will prove useful to the radiologists interpreting imaging studies of ROC mucormycosis.

Abstract
Mucormycosis is caused by the fungi belonging to the order Mucorales and class Zygomycetes. The incidence of mucormycosis has increased with the onset of the severe acute respiratory syndrome coronavirus 2 infections leading to the coronavirus disease 2019 (COVID-19) pandemic. This rise is attributed to the use of immunosuppressive medication to treat COVID-19 infections. Authors have retrospectively collected data of our cases of mucormycosis diagnosed from April 2020 to April 2021 at our institute. A total of 20 patients with rhinocerebral mucormycosis were studied. Most of the study subjects were male patients (90%) and were of the age group 41-50 years. Most patients in the review had comorbidities (85%) with diabetes being the most common comorbidity. Para nasal sinuses were involved in all the cases. Involvement of the neck spaces was present in 60% of the cases. Involvement of the central nervous system was present in 80% of the cases. Orbital involvement was present in 90% of the cases. The authors reviewed the various imaging findings of mucormycosis on computed tomography and magnetic resonance imaging in this article.

Abstract
This article presents guidelines for initial imaging utilization in patients presenting with sinonasal disease, including acute rhinosinusitis without and with suspected orbital and intracranial complications, chronic rhinosinusitis, suspected invasive fungal sinusitis, suspected sinonasal mass, and suspected cerebrospinal fluid leak. CT and MRI are the primary imaging modalities used to evaluate patients with sinonasal disease. Given its detailed depiction of bony anatomy, CT can accurately demonstrate the presence of sinonasal disease, bony erosions, and anatomic variants, and is essential for surgical planning. Given its superior soft tissue contrast, MRI can accurately identify clinically suspected intracranial and intraorbital complications, delineate soft tissue extension of tumor and distinguish mass from obstructed secretions.The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
Purpose To compare the clinical profile of COVID-related and non-COVID-related rhino-orbito-cerebral invasive fungal disease. Methods We have compared the comorbidities, clinical features, course of the disease and outcome between COVID-related and non-COVID-related acute invasive fungal rhinosinusitis (AIFRS) of the rhino-orbito-cerebral form. Results HbA1c and blood sugar at the time of admission were significantly higher in the non-COVID group (P < 0.05). Duration of stay, and use of steroids were significantly higher among the COVID group (P < 0.05). The period of hospital stay was significantly higher in the COVID group. The overall survival in the COVID group was 67.57%. In the non-COVID group the overall survival was 61.90%.This study found that odds of surgical treatment was significantly lower among non-survivors (P < 0.05). Similarly patients who developed stages 3 & 4 of the disease had a lower survival rate (P < 0.05). Conclusion Diabetes mellitus is a key risk factor for the development of AIFRS. Pre-existing, grossly uncontrolled DM was the predisposing factor in the non-COVID group. Deranged glucose profile associated with COVID illness and its treatment and immunological disturbances in a vulnerable population, contributed to the surge in cases of AIFRS in the COVID-19-related group. Patients who underwent combined medical and surgical treatment had a significantly better outcome following AIFRS.

Abstract
OBJECTIVES Acute invasive fungal sinusitis (AIFS) is a rapidly progressive disease, whose delayed identification results in poor outcomes, especially in immunocompromised individuals. A surge in of AIFS in the wake of the COVID-19 pandemic has lent additional morbidity and mortality to an already precarious clinical scenario. Early detection of AIFS in individuals who are symptomatic/ at risk can allow early therapy, enabling better patient outcomes. Our study aims to determine optimal soft-tissue markers on CT for the early detection of AIFS. METHODS In this case-control study, 142 patients with equal distribution of subjects were chosen based on histopathological diagnosis of AIFS; and their non-contrast CT scans were retrospectively assessed to determine the diagnostic utility of specific soft-tissue markers that would enable diagnosis of AIFS. RESULTS A total of nine markers with adequate sensitivity and specificity were identified, including pterygopalatine and sphenopalatine fossae, inferior orbital fissure and nasolacrimal duct involvement, premaxillary thickening, retro-antral and orbital stranding, and infratemporal muscle oedema. It was determined that the combined occurrence of any three out of nine markers was 91.5% sensitive and 95.9% specific for diagnosis of AIFS (p < 0.005). CONCLUSION Early, accurate detection of AIFS in predisposed individuals is possible with identification of soft-tissue markers on NECT, enabling early intervention. ADVANCES IN KNOWLEDGE Being the aggressive disease that it is, AIFS may be managed early if the index of suspicion is held high via CT imaging; which our diagnostic checklist aims at enabling.

Abstract
BACKGROUND AND PURPOSE The purpose is to provide a comprehensive report describing the clinical and imaging features of Coronavirus disease 2019 (COVID-19)-related acute invasive fungal sinusitis (AIFS) and associated comorbidities. METHODS A retrospective study was conducted on 25 patients (12 males and 13 females, mean age of 53.9±9.1 years). All patients had positive polymerase chain reaction test for COVID-19 and histopathological proof of AIFS. Patients underwent computed tomography (CT) and magnetic resonance examinations to assess sinonasal, orbital, and cranial spread. RESULTS The most prevalent comorbidity among the study cohort was diabetes mellitus (DM). Twenty-one patients (84%) were diagnosed in the post-COVID-19 period after hospital discharge, with a mean interval of 19.1±9.2 days. Steroid treatment was given to 19 patients (76%). Orbital manifestations were the presenting symptoms in all patients, followed by facial edema, nasal discharge, and neurological symptoms. Sinonasal involvement ranged from mucosal thickening to complete sinus opacification by a predominant isodensity on CT, low T1, and high T2 signal intensity with variable enhancement patterns. Twenty-four patients had a unilateral orbital extension, and 12 patients showed signs of intracranial extension. Bone involvement was detected in 16 patients (64%). Follow-up scans in 18 patients (72%) showed rapid progression of the disease. Eight patients (32%) died, six from neurological complications and two from severe respiratory failure. CONCLUSION Steroids, DM, and severe COVID-19 are the major risk factors of AIFS in the post-COVID-19 era. Imaging scans in all patients revealed different sinonasal, facial, orbital features, and intracranial involvement with rapid progression of the findings on follow-up scans.

Abstract
OBJECTIVES Acute invasive fungal sinusitis AIFS has high mortality rate, and its incidence has increased without explanation in Covid-19 era. Proper diagnosis and effective surgical debridement have a crucial role in decreasing this high mortality rate. MRI could detect early ischemic changes with localization of extrasinus devitalized fungal inflamed tissue to guide surgical intervention. STUDY DESIGN Prospective study SETTING: ORL-HNS department -Zagazig University. METHODS T1 with gadolinium and T2 fat suppression sequences were investigated and correlated with surgical findings in cases recently recovered from Covid-19 "seroconversion". Loss of contrast enhancement LOCE/black sign in T1+G was hypothesized to reflect necrotic areas while hyperintense signal/white sign in T2 fat suppression was hypothesized to correlate with severely inflamed devitalized tissue in periantral region These radiological findings were correlated with intraoperative findings to identify positive predictive finding. RESULTS 40 patients were included in this study, of which 38 had LOCE/ black sign in T1+G 95%. True ischemic turbinate was detected only in 35 cases (positive predictable value PPV= 92.1%). Hyperintense signal/ white sign in T2 fat suppression was detected in orbit, pterygopalatine-infratemporal fossa, sphenoid process, zygoma, external skin, and these findings were correlated with intraoperative findings (PPV ranging from 72.7% to 100%). CONCLUSION MRI has a crucial role in localization of devitalized tissue, and subsequently guides surgical intervention.

Abstract
Background There has been a rapid rise in the number of COVID-19-associated rhino-orbital mucormycosis (CAROM) cases especially in South Asian countries, to an extent that it has been considered an epidemic among the COVID-19 patients in India. As of May 13, 2021, 101 CAROM cases have been reported, of which 82 cases were from India and 19 from the rest of the world. On the other hand, pulmonary mucormycosis associated with COVID-19 has a much lesser reported incidence of only 7% of the total COVID-19-associated mucormycosis cases (Singh AK, Singh R, Joshi SR, Misra A, Diab Metab Syndr: Clin Res Rev, 2021). This case report attempts to familiarize the health care professionals and radiologists with the imaging findings that should alarm for follow-up and treatment in the lines of CAROM. Case presentation Rhino-orbital mucormycosis (ROM) is a manifestation of mucormycosis that is thought to be acquired by inhalation of fungal spores into the paranasal sinuses. Here, we describe a 55-year-old male, post COVID-19 status with long standing diabetes who received steroids and ventilator therapy for the management of the viral infection. Post discharge from the COVID-19 isolation ICU, the patient complained of grayish discharge from the right nostril and was readmitted to the hospital for the nasal discharge. After thorough radiological and pathological investigation, the patient was diagnosed with CAROM and managed. Conclusion Uncontrolled diabetes and imprudent use of steroids are both contributing factors in the increased number of CAROM cases. Our report emphasizes on the radiological aspect of CAROM and reinforces the importance of follow-up imaging in post COVID-19 infection cases with a strong suspicion of opportunistic infections.

Abstract
Radiological investigations are essential for the diagnosis and classification of fungal rhinosinusitis; however, radiological findings might occasionally be misleading. Computed tomography (CT) scan and magnetic resonance imaging (MRI) complement each other, facilitating clinicians to arrive at a diagnosis. Hence, even with the best radiological modalities, correlation between clinical and microbiological findings is crucial for the accurate diagnosis of fungal rhinosinusitis. In addition, the role of traditional methods such as KOH microscopy and culture should be accurately evaluated. To this end, we aimed to diagnose rhinosinusitis with a fungal etiology based on radiological findings and subsequently correlate these findings with those of microbiological techniques, namely culture and KOH microscopy. A total of 57 clinically suspected fungal rhinosinusitis cases were included in the study. Radiological investigations were performed using either CT or MRI. Tissues samples were processed and analyzed using KOH microscopy and culture. The results of the study suggest that using a single method for the diagnosis of fungal rhinosinusitis is inadequate. Rather, the diagnosis should be based on radiological as well as microbiological findings, especially for cases that are clinically ambiguous.

Abstract
Mucormycosis (MCR) is a fulminant, potentially lethal, opportunistic fungal infection. Diabetes, immunocompromised states and elevated serum iron levels are the most important risk factors for contracting MCR infection. Recently, MCR co-infections have been observed in patients with COVID-19 disease owing to a complex interplay of metabolic factors and corticosteroid therapy. Rhino-orbito-cerebral mucormycosis (ROCM) is the most common clinical form of MCR infection and refers to infection of the nasal cavities, paranasal sinuses, neck spaces, orbits and intracranial structures. Sinonasal inoculation is typically the primary site of infection; the necrotising and angioinvasive properties of the fungus facilitate its spread into adjacent structures. In this review, we discuss the pertinent mycology and risk factors of MCR infection. The review also aims to acquaint the reader with the cross-sectional imaging appearances of ROCM and its complications. All the cases discussed in this pictorial essay are microbiologically and/or histopathologically proven cases of ROCM with concomitant COVID-19 infection.

Abstract
During rapid spread of coronavirus disease (COVID-19) globally, ever since WHO declared COVID-19 as pandemic, there have been various patterns of disease in terms of diagnosis, management and complications. Secondary infections are reportedly common in hospitalized and severely ill COVID-19 patients among which fungal being 10 times more common. Mucormycosis is amongst the most lethal form of Zygormycosis occurring in post COVID-19 patients. A varied patterns of disease involvement and spectrum of imaging features are observed in patients with mucormycosis in post COVID-19 patients. MRI has better efficacy than CT in detecting early invasion of mucormycosis. The goal of this review is to familiarize radiologists about the MR imaging spectrum of mucormycosis in post COVID-19 patients with potential diagnostic pitfalls in CT.

Abstract
Oral cavity is habitat for plethora of micro-organism causing various diseases. The most common includes dental caries, periodontal diseases, etc. Dental practice may rarely encounter unusual and subtle symptoms with nonpathognomonic clinical signs of several fatal diseases which may pretend like a common oral disease. Hence, the knowledge and clinical acumen of diagnostician are necessary for the early diagnosis of such fatal infections to prevent untoward consequences. Mucormycosis is an angioinvasive necrotic fungal infection with a high morbidity and mortality rate. It commonly occurs in patients with debilitating diseases and immunocompromised individuals. Clinically, it manifests as rhino-orbito-cerebral, pulmonary, cutaneous, gastrointestinal, renal, and disseminated form. Disease affecting the facial region is a challenge as it often disseminates with orbital and cranial involvement at the time of diagnosis. This article presents a case of mucormycosis which mimicked as severe periodontitis in a patient leading to delay in the diagnosis and challenges during the treatment.

Abstract
COVID-19 patients have been found to have an increased incidence of superadded fungal infections because of multiple factors such as impaired cell-mediated immunity, immunosuppressive therapy, and coexistent diabetes mellitus. Recently, there has been a significant rise in the COVID-19-associated mucormycosis and aspergillosis cases involving the sinonasal cavity and the lungs. Rhino-orbito-cerebral acute invasive fungal rhinosinusitis (AIFR) is a potentially life-threatening, invasive fungal infection. Early diagnosis followed by prompt medical management and surgical intervention is crucial for patient survival. The role of cross-sectional imaging (CT/MRI) is not only to suggest a diagnosis of invasive fungal sinusitis but also to delineate the complete extent of disease. Mapping the extent of orbital and intracranial disease has prognostic as well as management implications, as involvement of these sites marks a worse prognosis. A stepwise approach to evaluation of imaging of AIFR along with a pictorial depiction of the key imaging findings is presented.

Abstract
CONTEXT.— Acute invasive fungal rhinosinusitis (AIFRS) is an aggressive form of fungal sinusitis, which remains a significant cause of morbidity and mortality. Early diagnosis and intervention are keys to improving patient outcomes. Intraoperative consultation has shown promise in facilitating early surgical intervention, but the accuracy of frozen section has not been clarified in this setting. OBJECTIVES.— To assess the accuracy of frozen-section diagnosis in patients with clinically suspected AIFRS. DESIGN.— All cases of clinically suspected AIFRS during a 10-year period (2009-2019) were retrospectively reviewed. The frozen-section results were compared with the final permanent sections as well as the tissue fungal culture results, following which the accuracy of frozen section was determined. RESULTS.— Forty-eight patients with 133 frozen-section evaluations for AIFRS were included in the study. Thirty of 48 patients and 61 of 133 specimens were positive for AIFRS on final pathology. Of 30 positive patients, 27 (90%) had at least 1 specimen diagnosed as positive during intraoperative consultation; among the 61 positive specimens, 54 (88.5%) were diagnosed as positive during intraoperative consultation. Of 72 negative specimens, all were interpreted as negative on frozen section. Thus, frozen sections had a sensitivity of 88.5% (95% CI, 0.78-0.97), specificity of 100% (95% CI, 0.94-1), positive predictive value of 100% (95% CI, 0.92-1), and negative predictive value of 90.6% (95% CI, 0.82-0.97). CONCLUSIONS.— This study represents the largest series assessing the diagnostic accuracy of frozen section analysis in AIFRS. These findings are useful in frozen section-informed intraoperative decision making.

Abstract
A subset of diabetic COVID-19 patients treated with steroids, oxygen, and/or prolonged intensive care admission develop rhino-orbito-cerebral mucormycosis. Radiologists must have a high index of suspicion for early diagnosis, which prompts immediate institution of antifungal therapy that limits morbidity and mortality. Assessment of disease extent by imaging is crucial for planning surgical debridement. Complete debridement of necrotic tissue improves survival. Imaging features reflect the angioinvasive behaviour of fungal hyphae from the Mucoraceae family, which cause necrotising vasculitis and thrombosis resulting in extensive tissue infarction. Contrast-enhanced magnetic resonance imaging (MRI) is the imaging technique of choice. The classic “black turbinate” on contrast-enhanced imaging represents localised invasive fungal rhinosinusitis (IFRS). A striking radiological feature of disseminated craniofacial disease is non-enhancing devitalised and necrotic soft tissue at the orbits and central skull base. Sinonasal and extrasinonasal non-enhancing lesions in IFRS are secondary to coagulative necrosis induced by fungal elements. Multicompartmental and extrasinonasal tissue infarction is possible without overt bone involvement and caused by the propensity of fungal elements to disseminate from the nasal cavity via perineural and perivascular routes. Fungal vasculitis can result in internal carotid artery occlusion and cerebral infarction. Remnant non-enhancing lesions after surgical debridement portend a poor prognosis. Assessment for the non-enhancing MRI lesion is crucial, as it is a sole independent prognostic factor for IFRS-specific mortality. In this review, we describe common and uncommon imaging presentations of biopsy-proven rhino-orbito-cerebral mucormycosis in a cohort of nearly 40 COVID-19 patients.

Abstract
Coronavirus disease-associated mucormycosis (CAM) is an established clinical entity in India. In the past 4 months, there has been a sharp upsurge in the number of CAM cases in most parts of the country. Early diagnosis can be lifesaving. Magnetic resonance imaging (MRI) imaging remains the corner stone of management in patients with ROCM. This review discussed the utility of MRI imaging in ROCM with an emphasis on the ideal MRI protocol in a suspected case of ROCM, the pathways of spread of infection, the classic diagnostic features, MRI for staging of the disease, MRI for prognostication, MRI for follow up, and imaging features of common differentials in ROCM. The pit falls of MRI imaging and a comparison of CT and MRI imaging in ROCM are discussed. The clinical interpretation of areas of contrast uptake and those of necrosis and its relevance to treatment are discussed. This review aims to familiarize every member of the multidisciplinary team involved in managing these patients to be able to interpret the findings on MRI in ROCM.

Abstract
BACKGROUND The incidence of devastating opportunistic coinfections in patients with COVID-19 infection, their imaging features and their morbidity and mortality consequences need to be unraveled. METHODS This is a case series presenting the radiologic features and clinical presentation of acute invasive fungal rhino-orbital-cerebral sinusitis (AIFS) in eight hospitalized patients with confirmed COVID-19 infection. RESULTS Our patient cohort presented with symptoms of the invasive fungal disease within 12-35 days from their initial presentation with COVID-19 infection. The cross-sectional imaging features of AIFS associated with COVID-19 infection do not differ from those reported in the literature for AIFS associated with other risk factors, yet our patients had features of aggressive late-stage forms with high morbidity and mortality rate. CONCLUSION AIFS is a possible encounter in patients with COVID-19 patients and radiologists should be familiar with its imaging features.

Abstract
Objective The purpose of this study is to identify perioperative independent prognostic factors that are available to the consulting team to aid in determining prognosis in patients with acute invasive fungal sinusitis. Study Design Retrospective chart review of patients with biopsy-proven acute invasive fungal sinusitis from 2015 to 2018. Setting Academic tertiary care center. Methods Twenty-one patients were included from our single-center retrospective review. Kaplan-Meier graphs were created, and the Breslow test used to compare the curves to obtain P values. A univariate Cox regression analysis was performed on the data that were significant at 3 months from diagnosis. Results Twenty-one patients were included, and 17 (76%) had an underlying hematologic malignancy. Overall survival was 71% and 52% at 1 and 3 months, respectively, and 94% of patients with hematologic malignancy had an absolute neutrophil count ≤1 at diagnosis. Absolute neutrophil count values and fungal species were not associated with a difference in prognosis. Factors associated with decreased survival included current smoking and the absence of a rhinologist on the treatment team at the initial or subsequent debridement (hazard ratio, 3.03). Laboratory values such as beta-D-glucan and galactomannan were assessed in addition to disease extension at diagnosis. Conclusion This study presents a retrospective review of a single institution’s experience with acute invasive fungal sinusitis. Subspecialty level of care likely improves overall survival in these patients, whereas current smoking may imply a worse prognosis.

Abstract
The incidence of invasive mold disease (IMD) has significantly increased over the last decades, and IMD of the central nervous system (CNS) is a particularly severe form of this infection. Solid data on the incidence of CNS IMD in the pediatric setting are lacking, in which Aspergillus spp. is the most prevalent pathogen, followed by mucorales. CNS IMD is difficult to diagnose, and although imaging tools such as magnetic resonance imaging have considerably improved, these techniques are still unspecific. As microscopy and culture have a low sensitivity, non-culture-based assays such as the detection of fungal antigens (e.g., galactomannan or beta-D-glucan) or the detection of fungal nucleic acids by molecular assays need to be validated in children with suspected CNS IMD. New and potent antifungal compounds helped to improve outcome of CNS IMD, but not all agents are approved for children and a pediatric dosage has not been established. Therefore, studies have to rapidly evaluate dosage, safety and efficacy of antifungal compounds in the pediatric setting. This review will summarize the current knowledge on diagnostic tools and on the management of CNS IMD with a focus on pediatric patients.

Abstract
BACKGROUND AND PURPOSE Children with severe immunocompromise due to cancer therapy or hematopoietic cell transplant are at risk both for potentially lethal invasive fungal rhinosinusitis (IFRS), and for complications associated with gold-standard biopsy diagnosis. We investigated whether early imaging could reliably identify or exclude IFRS in this population, thereby reducing unnecessary biopsy. METHODS We reviewed clinical/laboratory data and cross-sectional imaging from 31 pediatric patients evaluated for suspicion of IFRS, 19 without (age 11.8 ± 5.4 years) and 12 with proven IFRS (age 11.9 ± 4.6 years). Imaging examinations were graded for mucosal thickening (Lund score), for fungal-specific signs (FSS) of bone destruction, extra-sinus inflammation, and nasal mucosal ulceration. Loss of contrast enhancement (LoCE) was assessed separately where possible. Clinical and imaging findings were compared with parametric or nonparametric tests as appropriate. Diagnostic accuracy was assessed by receiver operating characteristic (ROC) analysis. Positive (+LR) and negative likelihood ratios (-LR) and probabilities were calculated. RESULTS Ten of 12 patients with IFRS and one of 19 without IFRS had at least one FSS on early imaging (83% sensitive, 95% specific, +LR = 15.83, -LR = 0.18; P < .001). Absolute neutrophil count (ANC) ≤ 200/mm3 was 100% sensitive and 58% specific for IFRS (+LR = 2.38, -LR = 0; P = .001). Facial pain was the only discriminating symptom of IFRS (P < .001). In a symptomatic child with ANC ≤ 200/m3 , the presence of at least one FSS indicated high (79%) probability of IFRS; absence of FSS suggested low (<4%) probability. CONCLUSION In symptomatic, severely immunocompromised children, the presence or absence of fungal-specific imaging findings may effectively rule in or rule out early IFRS, potentially sparing some patients the risks associated with biopsy.

Abstract
The lacrimal drainage system (LDS) pathology is frequently encountered in the ophthalmology setting but is rarely discussed in the radiology literature. This is even truer for adult LDS lesions despite increase utilization of computed tomography and magnetic resonance in imaging for diagnosis of LDS pathology. The purpose of this image rich review is to highlight common adult LDS pathologies and introduce the radiologist to rare disease entities affecting this pathology rich anatomical region with emphasis on imaging findings, clinical presentation, and differential generation.

Abstract
Our purpose was to classify acute invasive fungal rhinosinusitis (AIFR) caused by Mucor versus Aspergillus species by evaluating computed tomography radiological findings. Two blinded readers retrospectively graded radiological abnormalities of the craniofacial region observed on craniofacial CT examinations obtained during initial evaluation of 38 patients with eventually pathology-proven AIFR (13:25, Mucor:Aspergillus). Binomial logistic regression was used to analyze correlation between variables and type of fungi. Score-based models were implemented for analyzing differences in laterality of findings, including the 'unilateral presence' and 'bilateral mean' models. Binary logistic regression was used, with Score as the only predictor and Group (Mucor vs Aspergillus) as the only outcome. Specificity, sensitivity, positive predictive value, negative predictive value and accuracy were determined for the evaluated models. Given the low predictive value of any single evaluated anatomical site, a 'bilateral mean' score-based model including the nasal cavity, maxillary sinuses, ethmoid air cells, sphenoid sinus and frontal sinuses yielded the highest prediction accuracy, with Mucor induced AIFR correlating with higher prevalence of bilateral findings. The odds ratio for the model while integrating the above anatomical sites was 12.3 (p < 0.001). PPV, NPV, sensitivity, specificity and accuracy were 0.85, 0.82, 0.92, 0.69 and 0.84 respectively. The abnormal radiological findings on craniofacial CT scans of Mucor and Aspergillus induced AIFR could be differentiated based on laterality, with Mucor induced AIFR associated with higher prevalence of bilateral findings.

Abstract
Head and neck imaging is an intimidating subject for many radiologists because of the complex anatomy and potentially serious consequences of delayed or improper diagnosis of the diverse abnormalities involving this region. The purpose of this article is to help radiologists to understand the intricate anatomy of the head and neck and to review the imaging appearances of a variety of nontraumatic head and neck conditions that bring patients to the emergency department, including acute infectious and inflammatory diseases and acute complications of head and neck neoplasms. These conditions are presented in five sections on the basis of their primary location of involvement: the oral cavity and pharynx, neck, sinonasal tract, orbits, and ears. Important anatomic landmarks are reviewed briefly in each related section.Online supplemental material is available for this article.©RSNA, 2019.

Abstract
BACKGROUND Acute invasive fungal sinusitis (AIFS) is a potentially life-threatening diagnosis in immunocompromised patients. Identifying patients who could benefit from evaluation and intervention can be challenging for referring providers and otolaryngologists alike. We aimed to develop and validate an accessible diagnostic tool to estimate the probability of AIFS. METHODS Retrospective chart review from 1999 to 2017 identified all patients evaluated for possible AIFS at a tertiary care center. AIFS was diagnosed by pathologic confirmation of fungal tissue angioinvasion. Stepwise selection and univariate logistic regression were used to screen risk factors for a multivariable predictive model. Model performance was assessed using Tukey's goodness-of-fit test and the area under the receiver operator characteristic curve (AUC). Model coefficients were internally validated using bootstrapping with 1000 iterations. RESULTS A total of 283 patients (244 negative controls, 39 with AIFS) were included. Risk factors in our final diagnostic model included: fever ≥38°C (log-odds ratio [LOR] 1.72; 95% CI, 0.53 to 2.90), unilateral facial swelling, pain, or erythema (LOR 2.84; 95% CI, 1.46 to 4.23), involvement of the orbit or pterygopalatine fossa on imaging (LOR 3.02; 95% CI, 1.78 to 4.26), and mucosal necrosis seen on endoscopy (LOR 5.52; 95% CI, 3.81 to 7.24), with p < 0.01 for all factors. The model had adequate goodness of fit (p > 0.05) and discrimination (AUC = 0.96). CONCLUSION We present an internally validated diagnostic tool to stratify the risk for AIFS. The estimated risk may help determine which patients can be observed with serial nasal endoscopy, which ones could be biopsied, and which ones would benefit from immediate surgical intervention.
