Abstract
Pulmonary mucormycosis is a rare but highly lethal fungal infection, usually affecting immunocompromised patients. Pulmonary mucormycosis was also a critical problem that complicated the later part of the clinical course of COVID-19 in India. Early diagnosis of the disease, combined with aggressive treatment, is crucial for patient survival. Fibreoptic bronchoscopy is a useful procedure for diagnosis of pulmonary mucormycosis, but image-guided percutaneous biopsy efficiently samples lesions abutting the chest wall. Biopsy is more yielding than cultures and imaging guided biopsy is required for lesions that cannot be microbiologically confirmed by fibreoptic bronchoscopy. We present a case series of four patients of pulmonary mucormycosis in whom ultrasound guided biopsy clinched the diagnosis. All the four patients were poor surgical candidates and underwent medical management with antifungal agents, and had successful clinical recovery and radiological resolution. Our case series illustrates the utility of ultrasound guided percutaneous biopsy as a diagnostic tool for sampling cavitatory disease due to pulmonary mucormycosis, when fibreoptic bronchoscopy failed to yield a diagnosis and the beneficial role antifungal agents as salvage therapy in poor surgical candidates.

Abstract
We report the case of a 63-year-old woman who presented with abdominal distension and pain two months ago, which worsened after eating. An abdominal CT examination revealed uneven thickening of the gastric wall on the greater curvature side of the gastric body, with progressive obviously enhancement. She was then examined by an upper endoscopy, which showed mucosal swelling on the greater curvature side of the lower gastric body with exudation of necrotic materials. Biopsies of the lesion were taken and histological results revealed a large number of broad-based and non-septate hyphae, with positive expression of PAS (Periodic Acid-Schiff) and hexamine silver stains, The patient was treated with amphotericin B liposomal antifungal therapy and remained under surveillance for six months without evidence of disease progression by follow-up upper endoscopy.

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
PURPOSE To assess whether transcutaneous retrobulbar amphotericin B injections (TRAMB) reduce exenteration rate without increasing mortality in rhino-orbital-cerebral mucormycosis (ROCM). METHODS In this retrospective case-control study, 46 patients (51 eyes) with biopsy-proven ROCM were evaluated at 9 tertiary care institutions from 1998 to 2021. Patients were stratified by radiographic evidence of local orbital versus extensive involvement at presentation. Extensive involvement was defined by MRI or CT evidence of abnormal or loss of contrast enhancement of the orbital apex with or without cavernous sinus, bilateral orbital, or intracranial extension. Cases (+TRAMB) received TRAMB as adjunctive therapy while controls (-TRAMB) did not. Patient survival, globe survival, and vision/motility loss were compared between +TRAMB and -TRAMB groups. A generalized linear mixed effects model including demographic and clinical covariates was used to evaluate the impact of TRAMB on orbital exenteration and disease-specific mortality. RESULTS Among eyes with local orbital involvement, exenteration was significantly lower in the +TRAMB group (1/8) versus -TRAMB (8/14) (p = 0.04). No significant difference in mortality was observed between the ±TRAMB groups. Among eyes with extensive involvement, there was no significant difference in exenteration or mortality rates between the ±TRAMB groups. Across all eyes, the number of TRAMB injections correlated with a statistically significant decreased rate of exenteration (p = 0.048); there was no correlation with mortality. CONCLUSIONS Patients with ROCM with local orbital involvement treated with adjunctive TRAMB demonstrated a lower exenteration rate and no increased risk of mortality. For extensive involvement, adjunctive TRAMB does not improve or worsen these outcomes.

Abstract
We describe two cases of extensive indolent calvarial osteomyelitis after rhino-orbital-mucormycosis in diabetic patients previously diagnosed with COVID-19. Both patients presented with acute rhino-orbital symptoms about one month after being diagnosed with COVID-19. Treatment with intravenous liposomal Amphotericin B and prompt radical surgical debridement was instituted, but calvarial osteomyelitis ensued and persisted chronically despite maintenance of antifungal therapy and partial debridement of necrotic calvarial bone. The patients were discharged to continue antifungal therapy on a day-hospital regime. After more than 8 months of treatment, they remain with radiological signs of osteomyelitis but with no symptoms or intracranial extension of the infection. Calvarial indolent osteomyelitis secondary to mucormycosis is extremely rare, and little is known regarding its treatment. We believe it can be controlled with medical treatment and partial bony debridement although more studies are necessary to better define therapy.

Abstract
Mucormycosis is an invasive fungal infection that usually affects patients with immunocompromised conditions. In the context of the COVID-19 pandemic and the following corticosteroid therapy, mucormycosis prevalence has increased. The situation may be more complicated with some underlying diseases such as diabetes mellitus. In addition, due to the vicinity of maxillary bone to the nasal cavity and paranasal sinuses, which are the main routes for the infection to spread, dentists, maxillofacial radiologists, and surgeons may be the first to encounter these patients. Post-COVID mucormycosis osteomyelitis is one of the complications of this infection Bone destruction and the erosion or breach of cortical boundaries of the maxilla and the bone structures in the vicinity of paranasal sinuses are the most critical radiographic findings of post-covid osteomyelitis. Herein, there are some cases of post-covid mucormycosis osteomyelitis involving the maxillary and other facial bones.

Abstract
BACKGROUND Identifying early predictors of severe Covid-19 associated mucormycosis (CAM) can help improve management and treatment outcomes. OBJECTIVES Primary: To identify clinical and radiological predictors of disease severity in CAM. Secondary: To describe patterns of central nervous system (CNS) involvement in CAM. METHODS A total of 71 patients with CAM were included in the study. Based on the anatomical extent of involvement on MRI, patients were divided into three groups: Sinus (paranasal sinuses), Orbit (orbital spread), and CNS (CNS spread). Clinical parameters and radiological patterns of involvement of sinuses and extra sinus spaces were studied between the three groups. Patterns of CNS involvement were also described. RESULTS A shorter time lag between COVID-19 infection and CAM, as well as high HbA1C levels, were found to be associated with severe disease. Involvement of the sphenoid, ethmoid and frontal sinuses, T1 hyperintense signal in the sphenoid, as well as bony involvement of the sphenoid sinus, were significantly associated with severe disease. Extra-sinus spread into pre/retroantral space, pterygopalatine fossa, and masticator spaces were also significantly associated with a severe disease course. The most common pattern of CNS spread was cavernous sinus involvement, followed by pachymeningeal spread and cranial nerve involvement. CONCLUSION Early identification of the above-described predictors in patients presenting with CAM can help detect those at risk for developing severe disease. A longer duration of amphotericin, combined with a more aggressive surgical approach in selected cases, may lead to better long-term outcomes.

Abstract
Mucormycosis of temporal bone is extremely rare. They are usually associated with host immunodeficiency, are difficult to diagnose, and many cases are fatal. We performed a literature review and found only 10 reported cases of temporal bone mucormycosis. We present a case of temporal bone mucormycosis involving the temporomandibular joint and infratemporal fossa in a 53-year-old woman with diabetes mellitus who presented with unbearable otalgia. Computed tomography and magnetic resonance imaging demonstrate inhomogeneous density mass in the parapharyngeal and retropharyngeal space accompanied with lytic bone destruction on the temporomandibular joint. After undergoing a biopsy of the left infratemporal fossa, the patient's pathology exhibited fungal hyphae consistent with mucormycosis. To our knowledge, this is the first report of temporal bone mucormycosis with extensive involvement of temporomandibular joint and its adjacent structures, which exhibited no otologic or rhinologic signs. A definitive diagnosis is made by biopsy.

Abstract
COVID-19-associated rhino-orbital cerebral mucormycosis (ROCM) has a rapidly evolving course with high morbidity and mortality. We describe imaging features of COVID-19-associated ROCM based on noncontrast computed tomography (NCCT). This retrospective single-center observational study included 50 patients with COVID-19 from January 1, 2021 to June 30, 2021 who subsequently developed ROCM confirmed by fungal culture studies. All patients underwent NCCT of the paranasal sinuses as the diagnostic workup. The involvement of the nasal cavity, paranasal sinuses, orbits, and intracranial cavity was identified and graded. The ethmoid sinuses were most commonly involved [right (n = 46 of 50) > left (n = 45 of 50)], followed by the maxillary, sphenoid, and frontal sinuses. Thinning and erosions of the hard palate were noted in 18% of patients (n = 9), whereas 34% (n = 17) showed dehiscence of the lamina papyracea. Retromaxillary fat stranding was noted in 68% of patients (n = 34). Severe ethmoid sinusitis was associated significantly with ipsilateral pterygopalatine fossa involvement. The extraocular muscles were involved in 64% of patients (n = 32), with 84% (n = 42) showing orbital fat stranding. Proptosis of the affected eye was seen in 66% of patients, optic nerve involvement in 52%, and irregularity of globe contour in 12% (n = 6). The cavernous sinuses were affected in 10% of patients (n = 5), with three of them having temporal infarcts. COVID-19-associated ROCM is an acute, invasive fungal disease characterized by multisinus involvement, often with orbital and intracranial extension. Bilateral involvement with rapid progression should alert one to underlying COVID-19 disease.

Abstract
RATIONALE AND OBJECTIVES Rhino‑Orbital‑Cerebral Mucormycosis (ROCM) is a life-threatening opportunistic fungal infection, which mostly affects immunocompromised patients. There has been a notable rise in the incidence of ROCM during the COVID-19 outbreak. In this study we described imaging characteristics of ROCM in detail, from early sinonasal inflammation to late intracranial involvement. MATERIALS AND METHODS In this retrospective study, Computed Tomography (CT) scan and Magnetic Resonance Imaging (MRI) of 48 patients with proven ROCM in biopsy or culture were evaluated. All the patients had a history of COVID-19 infection within the previous three months. The imaging findings were described and the frequency of different parameters was reported. RESULTS Paranasal inflammation was detected in all the patients on imaging. The most common involved paranasal sinuses were ethmoid sinuses (97.9%). On diffusionweighted images, restricted diffusion was seen in the paranasal sinuses of 81.1% of the patients. In addition, sinus wall bone involvement was observed in 87.5% of the cases. The most common anatomical sites for extrasinus involvement were the retroantral soft tissue (89.6%) and orbital cavity (87.5%). Dacryocystitis in 50%, optic nerve inflammation in 43.2%, globe involvement in 18.9%, and trigeminal nerve involvement in 16% of the patients were detected. There was extension of inflammation through the cavernous sinuses and alongside the internal carotid arteries in 24% of the patients. CONCLUSION Characteristic imaging findings of ROCM not only play a vital role in the early diagnosis of this infection, but they also contribute to the assessment of the extension of inflammation, which is vitally important in surgical planning.

Abstract
OBJECTIVES To describe the extent and imaging findings of COVID-associated rhino-orbital-cerebral mucormycosis on magnetic resonance imaging and to evaluate the value of MRI severity score in grading the extent of involvement. METHODS Proven cases of ROCM with a history of concurrent or recently (<6 weeks) treated COVID-19 underwent MRI at the initial presentation. Findings were charted for each anatomical structure and the extent of involvement was scored for sinonasal, extra-sinus soft tissues, orbits, and brain. MR severity score was defined by summing up the individual scores of each compartment (sinonasal 20, orbital 20, soft tissue 10, and brain 10) and a total score out of 60 was assigned. RESULTS A total of 47 patients were included in our study with variable involvement of sinonasal compartment (n = 43), extra-sinus soft tissue (n = 25), orbits (n = 23), and brain (n = 17). In the sinonasal compartment, T2, DWI, and post-contrast T1 were the most useful sequences. A significantly higher mean sinonasal score was associated with mortality (p = 0.007). In the orbits, a combination of STIR (orbital fat and extraconal muscles), DWI (optic nerves), and post-contrast images (superior ophthalmic vein) were the most accurate sequences. A higher mean orbital score was associated with vision loss (p = 0.001). Patients with uncontrolled diabetes had greater extent of cranial involvement. CONCLUSION A combination of magnetic resonance sequences is required to correctly evaluate the involvement of individual structures and thus to assign the correct MR scoring. The proposed MR severity score can effectively and objectively evaluate the severity of COVID-associated ROCM.

Abstract
The patient was a man in his 70s. During the treatment for acute myeloid leukemia, abdominal pain and bloody stools appeared. A diagnosis of small intestinal ileus was made by computed tomography scan. Treatment with an ileus tube did not improve his condition, and enteroscopy revealed the presence of ileal ulcers. Based on histological examination, small intestinal mucormycosis was suspected, and thus, antifungal drugs were administered. However, the patient developed perforated peritonitis and underwent small intestine resection. He was finally diagnosed with small intestinal mucormycosis with the help of the resected specimen. The gastrointestinal form of mucormycosis rarely occurs, and small intestinal lesions are very rare. Enteroscopy was helpful in its diagnosis and treatment.

Abstract
Rhino-orbito-cerebral mucormycosis (ROCM) has regained significance following its resurgence in the second wave of the COVID-19 pandemic in India. Rapid and progressive intracranial spread occurs either by direct extension across the neural foraminae, cribriform plate/ethmoid, walls of sinuses, or angioinvasion. Having known to have a high mortality rate, especially with intracranial extension of disease, it becomes imperative to familiarise oneself with its imaging features. MRI is the imaging modality of choice. This pictorial essay aims to depict and detail the various intracranial complications of mucormycosis and to serve as a broad checklist of structures and pathologies that must be looked for in a known or suspected case of ROCM.

Abstract
Mucormycosis is relatively uncommon, fulminant, progressive, life threatening fungal disease which is most often seen in debilitating patients with immunocompromised condition. Mucormycosis cases are seen in patients with the use of systemic steroids in the treatment of severely affected COVID-19 cases and also in the patients with uncontrolled diabetes which causes immunosuppression are being reported with mucormycosis. The main symptoms of this disease include pain on the temporal and the orbital region of the affected side which could be throbbing or lancinating type, mobility of the teeth, jaw pain and often swelling is present which could be extraoral and intraoral both or sometimes only intraorally. The diagnostic approach in such cases is done with the help of clinical diagnosis, histopathology and with advanced imaging like cone beam computed tomography, magnetic resonance imaging and computed tomography. We here used cone beam computed tomography imaging that revealed haziness in the sinuses and breach in cortical bone of the affected area which confirmed the diagnosis of mucormycosis. Early treatment planning like administration of antifungal drugs and surgical debridement will be life saving in such a deadly disease.

Abstract
We herein describe a patient with pulmonary mucormycosis and acute myelogenous leukemia. Computed tomography showed a widened pulmonary artery, a bronchopleural fistula, and the Westermark sign. Despite worsening hemoptysis, the operation was delayed for 6 months. The operation was very complicated and difficult. A thorough preoperative examination, adequate preoperative preparation, appropriate surgical timing, and rich clinical and surgical experience were the keys to successful surgery in this case.

Abstract
The patient was a male in his 60s, who had undergone bone marrow transplantation because of lymphoblastic leukemia. He suffered from chest pain two weeks after the transplantation. A chest computed tomography(CT) showed reversed halo sign( RHS) in the right upper lobe of the lung. A bronchoscopic lung biopsy revealed mycelia, and the patient was diagnosed with pulmonary mucormycosis. Although antifungal drugs were administered, no significant improvements were observed. A right upper lobectomy of the lung was successfully performed, and no postoperative complications occurred. Pathological examination found nodular lesions with extensive necrotic foci inside, and inflammatory granulation tissue and mucormycosis with hyphae (+) were found through Grocott staining. RHS in leukemia patients with neutropenia is specific to pulmonary mucormycosis. Pulmonary mucormycosis is a life-threatening disease, and urgent treatment intervention including surgical treatment is advisable.

Abstract
A case is presented of mucormycosis in a patient with acute myeloblastic leukemia following liver transplantation for Wilson's disease. A 58-year-old female was admitted to the Department of Haematology with deterioration of her general condition, loss of appetite, tiredness and difficulty with mental contact for a few days. Blood and urine cultures for bacteria and fungus, galactomannan antigen were negative. Whole body computed tomography demonstrated bilateral hilar lymphadenopathy with necrotic lesions: splenomegaly with a hypodensive lesion 13 × 20 × 19 mm and lower pulmonary infiltrates suggested fungal etiology. Magnetic resonance imaging of the brain showed thickened meninges. Finally, mucormycosis was diagnosed. Treatment with amphotericin B lipid complex was started, resulting in an partial improvement of the general condition and decreased level of inflammatory markers. However, the patient's condition continued to deteriorate, with sepsis etiology Escherichia coli, and despite the intensive managements she eventually died.

Abstract
Mucormycosis is a rare opportunistic fungal infection, often life-threatening. We report an unusual case of rhinocerebral mucormycosis in an immunocompetent patient. A 23-year-old male presented with headache, speech disturbance and hearing difficulty for 4 weeks. Magnetic resonance imaging (MRI) revealed right cerebellar abscess and enhancing soft tissue in the nasal cavity, extending to cranial and infratemporal fossae. Computed tomography (CT) revealed the widening of foramen rotundum and sclerosis involving the sphenoid and ethmoid sinuses. MR Spectroscopy revealed multiple peaks between 3.6 and 3.8 parts per million (ppm) which could represent trehalose. Nasal mucosa scrapings confirmed mucormycosis. Suspicion of a fungal infection needs to be considered even in the absence of immunocompromised status.

Abstract
Background Invasive mucormycosis (IM) is an emerging life-threatening fungal infection. It is difficult to obtain a definite diagnosis and to initiate timely intervention. Mucorales-specific T cells occur during the course of IM and are involved in the clearance of the infection. We have evaluated the feasibility of detecting Mucorales-specific T cells in hematological patients at risk for IM, and have correlated the detection of such cells with the clinical conditions of the patients. Methods and Findings By using an enzyme linked immunospot assay, the presence of Mucorales-specific T cells in peripheral blood (PB) samples has been investigated at three time points during high-dose chemotherapy for hematologic malignancies. Mucorales-specific T cells producing interferon-γ, interleukin-10 and interleukin-4 were analysed in order to detect a correlation between the immune response and the clinical picture. Twenty-one (10.3%) of 204 patients, accounting for 32 (5.3%) of 598 PB samples, tested positive for Mucorales-specific T cells. Two groups could be identified. Group 1, including 15 patients without signs or symptoms of invasive fungal diseases (IFD), showed a predominance of Mucorales-specific T cells producing interferon-gamma. Group 2 included 6 patients with a clinical picture consistent with invasive fungal disease (IFD): 2 cases of proven IM and 4 cases of possible IFD. The proven patients had significantly higher number of Mucorales-specific T cells producing interleukin-10 and interleukin-4 and higher rates of positive samples by using derived diagnostic cut-offs when compared with the 15 patients without IFD. Conclusions Mucorales-specific T cells can be detected and monitored in patients with hematologic malignancies at risk for IM. Mucorales-specific T cells polarized to the production of T helper type 2 cytokines are associated with proven IM and may be evaluated as a surrogate diagnostic marker for IM.

Abstract
A fungus ball is an extramucosal fungal proliferation that completely fills one or more paranasal sinuses and usually occurs as a unilateral infection. It is mainly caused by Aspergillus spp in an immunocompetent host, but some cases of paranasal fungal balls reportedly have been caused by Mucor spp. A Mucor fungus ball is usually found in the maxillary sinus and/or the sphenoid sinus and may be black in color. Patients with mucormycosis, or a Mucor fungal ball infection, usually present with facial pain or headache. On computed tomography, there are no pathognomonic findings that are conclusive for a diagnosis of mucormycosis. In this article we report a case of mucormycosis in a 56-year-old woman and provide a comprehensive review of the literature on the "Mucor fungus ball." To the best of our knowledge, 5 case reports (8 patients) have been published in which the fungus ball was thought to be caused by Mucor spp.

Abstract
The case of a 9-year-old boy is presented in this article who developed a rare fungal infection of central nervous system. The histopathologic examination has revealed mucormycosis. The diagnosis wasn't confirmed microbiologically as the culture and PCR were negativ. After the iv administered Amphotericin B lipid complex the MR images of the brain have improved. The mucormycosis classically develops in immunodeficient patients and presents an acute, fulminant, mostly lethal infection. This case is very unusual, because the chronic, isolated CNS mucormycosis has slowly developed in immuncompetent patient and only one symptom was the long existing headache. The aim of this paper is reporting the case history and to find out the possible way of infection.

Abstract
Diabetes mellitus is an important risk factor for infections caused by fungi. Candidiasis is the most frequent fungal infection in diabetic patients, followed by aspergillosis, cryptococcosis, and mucormycosis. Fungal infection is a serious cause of morbidity and mortality in immunocompromised hosts. Diagnostic imaging plays an important role in the early diagnosis and treatment for these infections, especially for the pulmonary infection. Although imaging findings of pulmonary fungal infection are various, ground-glass opacity surrounding nodules or masses called "CT halo sign" is a relatively characteristic finding. In this review, we discuss the imaging finding of fungal infection particularly focusing on the pulmonary lesions.

Abstract
Pulmonary mucormycosis is a rare, frequently fatal, fungal infection. It is usually seen in the presence of various immunocompromised states, such as diabetes mellitus, haematological malignancy or renal transplantation. In the absence of underlying predisposing conditions, presentation with infiltrates, consolidation, cavitation and mass lesion have been reported. We describe a 50-year-old man who presented with cough and chest pain for six months. Chest radiograph and computed tomography showed bilateral multiple pulmonary nodules. Surgical lung biopsy revealed angioinvasive mucormycosis. He had complete recovery with amphotericin therapy.

Abstract
OBJECTIVES Show the contribution of imaging to the diagnosis and follow-up of serious mucormycosis in immunodepressed patients. MATERIALS AND METHODS Retrospective analysis of the 5-year radiological data in serious forms of mucormycosis occurring in patients with bone marrow allografts who are in refractory chronic graft-versus-host disease after bone marrow transplantation from 2002 to 2005. The positive diagnosis was bacteriologically and pathologically positive in all cases. RESULTS This study involved three patients with isolated pulmonary involvement and two cases of disseminated mucormycosis. Areas of pulmonary condensations were found in all cases, one of whom had a low-attenuation zone and parenchymal nodules. The kidney, liver, and spleen lesions were clearly limited, hypoechogenic, hypodense, and homogenous with no peripheral contrast material uptake. There was thyroid involvement in the form of hypoechogenic nodules. Rapid growth of the lesions was observed on follow-up CT (n=3) and despite surgical treatment (n=2) and intensive medical management, all cases ended in death. CONCLUSION Mucormycosis is an integral part of the differential diagnosis of infectious syndromes in immunodepressed patients during the period after bone marrow transplantation. Imaging can assist in the diagnosis but pathological confirmation remains indispensable.

Abstract
Mucormycosis is a rare acute opportunistic infection caused by a saprophytic fungus, which belongs to the order Mucorales. This report describes intraoral mucormycosis in 2 children with acute leukemia who were undergoing chemotherapy and had febrile neutropenia. A 7-year-old boy with acute myeloid leukemia and a 9-year-old boy with acute lymphoblastic leukemia were referred to the Department of Pediatric Dentistry at Cukurova University for their intraoral soft tissue lesions, which were diagnosed as mucormycosis by histologic examination. While, for the first case, the lesion was debrided under general anesthesia and medical antifungal therapy was performed, only medical management was done, without any debridement, for the second case. Early recognition of mucormycosis is necessary to limit the spread of infection, which can lead to high morbidity and mortality. Therefore, health practitioners should be familiar with the signs and symptoms of the disease.

Abstract
We report a case of pulmonary multinodular mucormycosis in a Type 1 diabetic patient with diabetic ketoacidosis. He had a history of 20-pack-year tobacco use. The initial chest roentgenogram and thorax tomography (after the treatment of diabetic ketoacidosis) revealed multiple nodular lesions with cavitation in the upper lobes of pulmonary parenchyma. Resection of three nodular lesion demonstrated cheesy necrotic mass in the cavitating lesions. The diagnosis of pulmonary multinodular mucormycosis was made depending on the histopathologic examination yielding nonseptated right angle branching-shaped hyphae typical of mucormycosis. The patient was started on liposomal amphotericin B and discharged at the sixth week of therapy with a scheduled therapy of amphotericin B. When he came back after 33 months, he was metabolically unregulated under the insulin therapy. He confessed that he had been smoking heroin besides tobacco for the last 5 years. A new thorax computerized tomography showed that pulmonary nodules were slightly regressed but not resolved.

Abstract
Mucormycosis is a rare, saprophytic, invasive, and fulminant fungal disease. It occurs in immunocompromised patients such as those with diabetes mellitus or blood dyscrasia, or in patients under immunosuppressive therapy. A 17-year-old female patient with diabetic ketoacidosis presented with a black-colored lesion in the auricle and external ear canal. Physical examination showed necrosis of the auricle, external ear canal, and neighboring skin. She also had facial paralysis. Debridement of the necrotic tissues was performed and the samples were submitted for microbiologic and histopathologic examination, which showed nonseptate hyphae. Postoperatively, systemic amphotericin B was empirically administered. The patient died on the seventh day.

Abstract
Disseminated mucormycosis is a rare, mostly fatal infectious complication in immunocompromised haematological patients. The purpose of our study was to describe the multiorgan manifestations of disseminated mucormycosis documented at CT and MRI in four patients and correlate these with the pathological findings and patient outcome. Irrespective of the site of infection, infarction or haemorrhage are the constant features of invasive mycosis. Identification of one or both of these two major imaging findings in immunocompromised patients should be regarded as an indicator of possible infection by angiotropic fungi, including the genre Mucorales.

Abstract
PURPOSE To report on the successful treatment of periorbital zygomycosis (mucormycosis) with posaconazole, a broad-spectrum oral antifungal available for compassionate use. DESIGN Interventional case report. METHODS Review of a medical record. RESULTS A 22-year-old male undergoing induction chemotherapy for acute lymphoblastic leukemia presented with periorbital cellulitis attributable to Rhizopus. The patient was initially treated with liposomal amphotericin B, surgical debridement, and reversal of immune compromise. The patient was switched to posaconazole because of amphotericin side effects and lack of improvement. He took posaconazole for five months while undergoing additional cycles of chemotherapy. Despite recurrent profound neutropenia, the periorbital infection resolved, he tolerated reconstructive procedures, and he did not develop orbital invasion. His Rhizopus isolate was highly susceptible to posaconazole in vitro. CONCLUSIONS Drug toxicities can limit the use of amphotericin in some patients with zygomycosis. Posaconazole shows promise as an alternative antifungal agent in the treatment of periorbital zygomycosis.

Abstract
Mucormycosis is a rare opportunistic infection, usually associated with immunocompromised states. Several conditions such as hematologic malignancy (leukemia, lymphoma, myeloma), solid organ transplantation, diabetes mellitus, corticosteroid therapy, or chemotherapy predispose patients to infection. The aim of this study was to present a single case of mucor infection after 900 consecutive liver transplantations. Rhinomaxillary mucormycosis must be suspected in a transplant recipient showing fever, maxillary swelling, and edema. This condition can be successfully treated with early diagnosis and a combination of aggressive surgery and antifungal therapy.

Abstract
PURPOSE The purpose of this study was to evaluate the sensitivity of percutaneous computed tomography (CT)-guided lung biopsy in the early diagnosis of fungal pulmonary infections. MATERIALS AND METHODS Between 1997 and 2003, 18 haematologically immunodeficient patients with suspected filamentous fungi infection and negative bronchoalveolar lavage (BAL) underwent percutaneous pulmonary biopsy to diagnose the nature of the infection. In all cases, infection developed during the post-chemotherapy bone marrow aplasia period. RESULTS Thirteen out of 18 patients had histologic findings positive for fungal infection: 8 Aspergillus and 5 Mucor. In 3 cases, biopsy was not specific, and in one case, the tissue sample was inadequate for a diagnosis; however, clinical course and response to drugs were compatible with fungal infection. In one patient, biopsy was positive for bronchoalveolar carcinoma. The sensitivity of percutaneous CT-guided biopsy was 80% and its positive predictive value was 100%. We only had one pneumothorax as a complication. CONCLUSIONS Percutaneous CT-guided lung biopsy is an easy, safe and reliable procedure to obtain diagnostic material. Histological discrimination between Aspergillus and Mucor is important in order to plan the correct therapeutic protocols, as Mucor is usually resistant to azoles.

Abstract
PURPOSE Rhinocerebal mucormycosis is a rare life threatening fungal infection observed in immunocompromised patients. We report six cases of patients with rhinocerebral mucormycosis confirmed histologically. Our study confirms the necessity of early diagnosis when clinical and CT findings are suggestive. MATERIALS AND METHODS This is a retrospective study including 6 diabetic patients (3 women and 3 men) aged from 28 and 63 years. Five patients had ethmoiditis evolving for a few days (3 to 5 days), and one patient was in an ketoacidotic coma and had a severe infectious syndrome with purulent rhinorrhea evolving for 4 days. All of our patients underwent computed tomography (CT) scan of the paranasal sinuses. MRI was performed in two patients with neurological findings. RESULTS Unilateral ethmoido-maxillary sinusitis was noted in 5 cases. Only one case of pansinusitis was found. All patients presented orbital involvement. Cerebral involvement was noted in 4 cases (cerebral venous thrombosis: 2 cases; abscess: 2 cases; cerebral ischemia: 2 cases). The diagnosis of mucormycosis was based on endonasal biopsy. When available, MRI allowed a more precise evaluation of the orbital and cerebral extension. CONCLUSION Mucormycosis is an opportunist mycosis due to mucoralis fungus. It is very invasive with a highly aggressive potential in diabetic or immunocompromised patients. Imaging study particularly CT scan, plays an important role in diagnosis especially to evaluate cerebral extension.
