Abstract
ABSTRACT Spinal cord sarcoidosis (SCS) is an uncommon disease with estimated incidence of 0.4% in patients with systemic sarcoidosis. Spinal cord sarcoidosis typically manifests late in the disease course and significantly contributes to patient morbidity. Therefore, early SCS diagnosis and prompt initiation of therapy are crucial. Herein, we report the case of a 51-year-old man with symptomatic SCS managed by 18 F-FDG PET/MRI, allowing diagnosis and treatment efficacy evaluation of spine involvement. We believe that the increasing clinical availability of hybrid PET/MRI devices will offer new opportunities for optimal management of patients with uncommon severe sarcoidosis localizations, such as nervous system.

Abstract
Sarcoidosis is an autoimmune multisystemic granulomatous disease with an unknown etiology. Löfgren syndrome (LS), an infrequent initial presentation of acute sarcoidosis, is characterized by the classic triad of acute arthritis, erythema nodosum (EN), and bilateral hilar lymphadenopathy (BHL). The presence of this triad offers high diagnostic specificity for sarcoidosis, eliminating the need for a confirmatory biopsy. Typically, LS follows a predictable, self-limiting clinical course. However, atypical presentations require early suspicion and closer monitoring. This case report highlights an unusual clinical manifestation of LS, marked by an incomplete presentation with acute panniculitis and joint lesions in the absence of EN. Acute sarcoidosis should be considered among the differential diagnoses when these clinical manifestations are present, and chest radiography should be performed to rule out BHL. In atypical cases, the disease course becomes less predictable, as exemplified in our case, where recurrence of the disease may occur, necessitating consistent monitoring.

Abstract
A diverse spectrum of pathologically distinct, nonneoplastic, proliferative conditions of the kidneys and urinary tract demonstrate a expansile growth pattern similar to that of neoplasms. The renal pseudotumors include myriad causes of infections as well as rare noninfectious causes such as sarcoidosis, amyloidosis, and immunoglobulin G4-related disease (IgG4-RD). Rare entities such as cystitis cystica, endometriosis, nephrogenic adenoma, and pseudosarcomatous myofibroblastic proliferation and distinct types of prostatitis comprise tumefactive nontumorous disorders that affect specific segments of the urinary tract. The pseudotumors of the kidneys and urinary tract demonstrate characteristic histopathologic and epidemiologic features, as well as protean clinical manifestations, natural history, and imaging findings. Many patients present with genitourinary tract-specific symptoms or systemic disease. Some cases may be incidentally discovered at imaging. Some entities such as perinephric myxoid pseudotumors, IgG4-RD, fibroepithelial polyp, and nephrogenic adenoma display specific anatomic localization and disease distribution. Imaging features of multisystem disorders such as tuberculosis, sarcoidosis, and IgG4-RD provide supportive evidence that may allow precise diagnosis. Fungal pyelonephritis, xanthogranulomatous pyelonephritis, IgG4-RD, actinomycosis, and endometriosis show markedly low signal intensity on T2-weighted MR images. Although some pseudotumors exhibit characteristic imaging findings that permit correct diagnosis, laboratory correlation and histopathologic confirmation are required for definitive characterization in most cases. A high index of suspicion is a prerequisite for diagnosis. Accurate diagnosis is critical for instituting optimal management while preventing use of inappropriate therapies or interventions. Surveillance CT and MRI are frequently used for monitoring the response of pseudotumors to therapy. ©RSNA, 2023 Quiz questions for this article are available in the supplemental material.

Abstract
Cross-sectional imaging of the upper abdomen, especially if intravenous contrast has been administered, will most likely reveal any acute or chronic disease harbored in the spleen. Unless imaging is performed with the specific purpose of evaluating the spleen or characterizing a known splenic lesion, incidentally discovered splenic lesions pose a small challenge. Solitary benign splenic lesions include cysts, hemangiomas, sclerosing angiomatous nodular transformation (SANT), hamartomas, and abscesses, among others. Sarcoidosis and tuberculosis, although predominantly diffuse micronodular disease processes, may also present as a solitary splenic mass lesion. In addition, infarction and rupture, both traumatic and spontaneous, may take place in the spleen. This review aims to describe the imaging features of the most common benign focal splenic lesions, with emphasis on the imaging findings as these are encountered on routine cross-sectional imaging from a multicenter pool of cases that, coupled with clinical information, can allow a definite diagnosis.

Abstract
Sarcoidosis is an inflammatory granulomatous disease of unknown etiology involving any organ or tissue along with any combination of active sites, even the most silent ones clinically. The unpredictable nature of the sites involved in sarcoidosis dictates the highly variable natural history of the disease and the necessity to cluster cases at diagnosis based on clinical and/or imaging common characteristics in an attempt to classify patients based on their more homogeneous phenotypes, possibly with similar clinical behavior, prognosis, outcome, and therefore with therapeutic requirements. In the course of the disease's history, this attempt relates to the availability of a means of detection of the sites involved, from the Karl Wurm and Guy Scadding's chest x-ray staging through the ACCESS, the WASOG Sarcoidosis Organ Assessment Instruments, and the GenPhenReSa study to the 18F-FDG PET/CT scan phenotyping and far beyond to new technologies and/or the current "omics." The hybrid molecular imaging of the 18F-FDG PET/CT scan, by unveiling the glucose metabolism of inflammatory cells, can identify high sensitivity inflammatory active granulomas, the hallmark of sarcoidosis-even in clinically and physiologically silent sites-and, as recently shown, is successful in identifying an unexpected ordered stratification into four phenotypes: (I) hilar-mediastinal nodal, (II) lungs and hilar-mediastinal nodal, (III) an extended nodal supraclavicular, thoracic, abdominal, inguinal, and (IV) all the above in addition to systemic organs and tissues, which is therefore the ideal phenotyping instrument. During the "omics era," studies could provide significant, distinct, and exclusive insights into sarcoidosis phenotypes linking clinical, laboratory, imaging, and histologic characteristics with molecular signatures. In this context, the personalization of treatment for sarcoidosis patients might have reached its goal.

Abstract
The relationship between chronic intestinal disease, including inflammatory bowel disease (IBD) and celiac disease (CelD), and pancreatic disorders has been little investigated. Although an increased risk of acute pancreatitis (AP), exocrine pancreatic insufficiency with or without chronic pancreatitis, and chronic asymptomatic pancreatic hyperenzymemia have been described in these patients, the pathogenetic link remains unclear. It may potentially involve drugs, altered microcirculation, gut permeability/motility with disruption of enteric-mediated hormone secretion, bacterial translocation, and activation of the gut-associated lymphoid tissue related to chronic inflammation. In addition, the risk of pancreatic cancer seems to be increased in both IBD and CelD patients with unknown pathogenesis. Finally, other systemic conditions (e.g., IgG4-related disease, sarcoidosis, vasculitides) might affect pancreatic gland and the intestinal tract with various clinical manifestations. This review includes the current understandings of this enigmatic association, reporting a clinical and pathophysiological overview about this topic.

Abstract
Sarcoidosis is a multisystemic granulomatous disease of unknown etiology. The diagnostic can be made by histological identification of non-caseous granuloma or by a combination of clinical criteria. Active inflammatory granuloma can lead to fibrotic damage. Although 50% of cases resolve spontaneously, systemic treatments are often necessary to decrease symptoms and avoid permanent organ dysfunction, notably in cardiac sarcoidosis. The course of the disease can be punctuated by exacerbations and relapses and the prognostic depends mainly on affected sites and patient management. FDG-PET/CT along with newer FDG-PET/MR have emerged as key imaging modalities in sarcoidosis, namely for certain diagnostic purposes, staging and biopsy guiding. By identifying with a high sensitivity inflammatory active granuloma, FDG hybrid imaging is a main prognostic tool and therapeutic ally in sarcoidosis. This review aims to highlight the actual critical roles of hybrid PET imaging in sarcoidosis and display a brief perspective for the future which appears to include other radiotracers and artificial intelligence applications.

Abstract
Pharynx/Larynx is an uncommon site of involvement of sarcoidosis. Isolated pharyngo-laryngeal sarcoidosis is extremely rare as most of the cases are part from multiorgan and systemic sarcoidosis. Pharyngo-laryngeal sarcoidosis is usually asymptomatic which could be attributed to its rare incidence as many cases pass unnoticed. Symptomatic cases usually present with hoarseness of voice. As the disease progress, the patient can present with progressive dysphagia to solid and liquid with globus sensation. We described an atypical involvement of almost the whole length of the pharynx with extension into the larynx in a 51-year-old woman who presented with progressive dysphagia. To the best of our knowledge, this is the first report to describe the imaging features of sarcoidosis involvement of the pharynx and larynx.

Abstract
PURPOSE To comprehensively summarize the characteristic radiological findings of laryngeal sarcoidosis. METHODS We reviewed patients with laryngeal sarcoidosis who underwent computed tomography (CT) and/or magnetic resonance imaging (MRI) and included 8 cases from 8 publications that were found through a systematic review and 6 cases from our institutions. Two board-certified radiologists reviewed and evaluated the radiological images. RESULTS Almost all cases exhibited supraglottic lesions 13/14 (92.9%) and most of them involved aryepiglottic folds (12/13, 92.3%), epiglottis (11/14, 78.6%), and arytenoid region (10/14, 71.4%). Most lesions were bilateral (12/14, 85.7%). All cases showed well-defined margins and a diffuse swelling appearance (14/14, 100%). Non-contrast CT revealed a low density (4/5, 80%). The contrast-enhanced CT showed a slight patchy enhancement predominantly at the margin of the lesion in most cases (12/13, 92.3%). In one case, T2-weighted images showed high signal intensity peripherally and low signal intensity centrally (1/1, 100%). Gadolinium-enhanced MRI showed moderate heterogeneous enhancement predominantly at the margin of the lesion (2/2, 100%). In one case, diffusion-weighted imaging showed intermediate signal intensity; the apparent diffusion coefficient value was 2.4 × 10-3 mm2/s. The larynx was the only region affected by sarcoidosis in 57.1% (8/14) of the cases. Involvement of the neck lymph nodes and distant organs was observed in 4/14 (28.6%) patients, respectively. CONCLUSION We summarized the CT and MRI findings of patients with laryngeal sarcoidosis. Knowledge of these characteristics is expected to facilitate prompt diagnosis and appropriate management.

Abstract
Abstract
Background
Focal lesions of the kidney comprise a spectrum of entities that can be broadly classified as malignant tumors, benign tumors, and non-neoplastic lesions. Malignant tumors include renal cell carcinoma subtypes, urothelial carcinoma, lymphoma, post-transplant lymphoproliferative disease, metastases to the kidney, and rare malignant lesions. Benign tumors include angiomyolipoma (fat-rich and fat-poor) and oncocytoma. Non-neoplastic lesions include infective, inflammatory, and vascular entities. Anatomical variants can also mimic focal masses.
Main body of the abstract
A range of imaging modalities are available to facilitate characterization; ultrasound (US), contrast-enhanced ultrasound (CEUS), computed tomography (CT), magnetic resonance (MR) imaging, and positron emission tomography (PET), each with their own strengths and limitations. Renal lesions are being detected with increasing frequency due to escalating imaging volumes. Accurate diagnosis is central to guiding clinical management and determining prognosis. Certain lesions require intervention, whereas others may be managed conservatively or deemed clinically insignificant. Challenging cases often benefit from a multimodality imaging approach combining the morphology, enhancement and metabolic features.
Short conclusion
Knowledge of the relevant clinical details and key imaging features is crucial for accurate characterization and differentiation of renal lesions.

Abstract
Incidental splenic focal findings are commonly encountered in clinical practice and frequently represent a diagnostic dilemma due to nonspecific imaging features. Most are benign, particularly in patients without a history of malignancy and without symptoms of fever, weight loss, or left upper quadrant or epigastric pain. Incidental malignant splenic processes are exceedingly rare. This article reviews imaging characteristics of incidental focal splenic findings, and proposes a practical approach for management of such findings, which can prevent unnecessary workup and its related drawbacks in clinical practice.

Abstract
We report the case of a 40-year-old man presenting at the emergency department with ankle and feet edema due to acute sarcoidosis (Lofgren syndrome). The diagnosis was suggested based on an ultrasound examination showing bilateral asymmetrical tenosynovitis of the flexor tendons with hypervascular subcutaneous cellulitis without any significant ankle and foot joint effusion or synovitis. This case report highlights the crucial role of ultrasound imaging as the first-line diagnostic tool in the investigation of a non-specific clinical condition, when performed by a knowledgeable sonographer with attention to detail. Radiologists performing ultrasound should be aware of the presenting ultrasound pattern of acute soft tissue sarcoidosis, and should include this entity in the differential diagnosis of patients with distal lower extremity swelling, tenosynovitis and hypervascular subcutaneous cellulitis, in order to narrow down the differential diagnosis and facilitate the clinical workup of the patient.

Abstract
There are a variety of less common diffuse liver diseases that can be asymptomatic or cause severe liver dysfunction. For the majority of them, the association of clinical, laboratory, and imaging findings are needed to narrow the differential diagnosis. In this article, we will review and describe the rarer diffuse liver diseases including drug-related liver disease, inflammatory and infectious diseases, and deposition disorders such as amyloidosis, glycogen storage disease, Wilson's disease, and alpha-1 antitrypsin deficiency. Abdominal radiologists should be familiar with the imaging features of different types of diffuse liver diseases to help the multidisciplinary team involved in the treatment of these patients. The data related to some of these conditions are scarce and sometimes experimental, but we want to demonstrate to the reader the value of imaging techniques in their analysis and introduce the potential of new imaging methods.

Abstract
Sarcoidosis is a granulomatous disorder of unknown etiology characterized by noncaseating granulomas virtually in every organ and tissue. This finding represents the most important diagnostic clue to reach a correct definition of sarcoidosis, although the biopsy is invasive and has several risk procedures. Several efforts are made to suspect the diagnosis of sarcoidosis by combining noninvasive elements, in particular from imaging, though these findings are often nonspecific and reflect the wide multifactorial pathogenesis. Every effort should be made to obtain a detailed radiological picture that, if associated with a suggestive clinical picture, could avoid the need of biopsy in some specific cases. In this narrative review, we aim to describe main computed tomography (CT) features of pulmonary and abdominal sarcoidosis, by reporting strengths and limits of this technique, in particular for the identification of extrapulmonary, isolated disease.

Abstract
Background Case reports describe incident sarcoidosis in persons with HIV (PWH). The association between HIV and risk of sarcoidosis, and differences in presentation in PWH, have not been systematically assessed. Methods Subjects were selected from the Veterans Aging Cohort Study (VACS), a longitudinal cohort study including veterans with HIV and matched uninfected veterans. This was a prospective observational analysis in which we evaluated both the incidence (via incidence rate ratio) and presentation and treatment (by comparison of rates of organ involvement and use of medications) of sarcoidosis in PWH compared with HIV-negative controls. We also assessed risk factors (via Cox regression) associated with the development of sarcoidosis including CD4 count and viral load trajectory. Results Of 1614 patients evaluated via chart review, 875 (54%) had prevalent sarcoidosis and 325 (20%) had confirmed incident sarcoidosis. Incident sarcoidosis occurred in 59 PWH and 266 uninfected. The incidence of sarcoidosis was lower in PWH than uninfected (incidence rate ratio [IRR], 0.61; 95% CI, 0.46-0.81) and especially low in patients with unsuppressed viremia (IRR, 0.04; 95% CI, 0.02-0.08) compared with uninfected). At diagnosis of sarcoidosis, the median CD4 count among PWH was 409 cells/mm3; 77% had HIV-1 RNA <500 copies/mL. No significant differences were observed between PWH and uninfected in terms of organ involvement, disease severity, or use of oral glucocorticoids. Conclusions HIV, particularly with persistent viremia, was associated with decreased risk of incident sarcoidosis; severity and treatment were similar between PWH and uninfected.

Abstract
Immunoglobulin G4-related disease (IgG4-RD) is a systemic fibroinflammatory disease characterized by focal or diffuse organ infiltration of IgG4-bearing plasma cells. The diagnosis of IgG4-RD is based on a combination of clinical, serologic, radiologic, and histopathologic findings. IgG4-RD has been reported to affect almost all organ systems. The kidney is the most frequently involved of the genitourinary organs. The most common renal manifestation of IgG4-RD is IgG4-RD tubulointerstitial nephritis, followed by membranous glomerulonephropathy and, less frequently, obstructive nephropathy involving the renal pelvis, ureter, or retroperitoneum. Renal parenchymal lesions may appear as multiple nodular lesions, diffuse patchy infiltrative lesions, or a single nodular lesion. Multiple small nodular cortical lesions are the most common imaging findings of IgG4-RD involving the kidney. Renal pelvic, sinus, or perinephric lesions can also occur. IgG4-RD involvement of other genitourinary organs including the ureter, bladder, urethra, and male and female reproductive organs is rare compared with kidney involvement but may show variable imaging findings such as a localized mass within or surrounding the involved organ or diffuse enlargement of the involved organ. Imaging findings of IgG4-RD involving the genitourinary system are nonspecific but should be differentiated from inflammatory and neoplastic lesions that mimic IgG4-RD. The online slide presentation from the RSNA Annual Meeting is available for this article. ©RSNA, 2020.

Abstract
CASE PRESENTATION The patient is a 37-year-old hospital employee and current smoker with a 10 pack-year smoking history, who presented with dyspnea, chest pain, and weight loss. She was in her usual state of health until 4 months prior to admission when she developed intermittent left-sided chest pain, cough productive of scant yellow sputum, fevers, and anorexia. Initial chest radiograph was normal and her outpatient physician prescribed azithromycin, which she took without improvement. One month prior to admission, a follow-up chest radiograph revealed a left-sided upper lobe consolidation; she received a course of levofloxacin without improvement. At follow-up, given her occupation, 13.6-kg unintentional weight loss, and persistent pulmonary symptoms and infiltrate despite treatment for pneumonia, her provider referred her for admission with particular concern for exclusion of active TB. As a hospital employee with clinical exposure, she underwent annual TB screening, which was always negative. She had no known exposure to patients with TB. Her most recent travel was to the Midwestern United States, without significant outdoors exposure. Review of systems was positive for wheezing, anorexia, and arthralgias of both knees and the left ankle and wrist. There was no hemoptysis, leg swelling, visual changes, palpitations, or muscle weakness.

Abstract
Sarcoidosis is an idiopathic, chronic, multisystem, granulomatous, inflammatory disease involving almost all organs. Sarcoidosis can occur with an atypical presentation of hepatosplenic involvement, like in the case of our patient. In this case report, we present a rare case of extrapulmonary sarcoidosis with isolated involvement of the liver and spleen in a 39-year-old Caucasian female. There is a possibility of this isolated involvement of an organ in the complete absence of pulmonary disease, which makes the diagnosis of sarcoidosis very difficult as it is usually not suspected. Ultrasound and CT are important in ruling out other differential diagnoses, but a definitive diagnosis is possible only on histological examination, differentiating sarcoid lesions from tuberculosis, primary biliary cirrhosis, metastasis, malignancy, and other granulomatous infections or diseases. Hence, the most credible criterion for diagnosis remains histology. After diagnosis, regular follow-up for systemic manifestations is recommended. Asymptomatic patients with hepatosplenic sarcoidosis have a good prognosis without any medical intervention, while patients with abnormal labs or symptoms must commence treatment.

Abstract
Idiopathic chilblain is a relatively common yet poorly recognized acrosyndrome. This literature review aims to better understand and draw attention to this disorder. Chilblain is a localized inflammation of the skin that occurs on exposure to cold but non-freezing wet weather. It usually resolves spontaneously. The etiology is uncertain, but vasospasm seems to play a role in this abnormal reaction to cold. Diagnosis is most often based on clinical presentation, but a skin biopsy can be useful in dubious cases. In histology, dermal edema and an inflammatory infiltrate are usually present. A distribution of the infiltrate particularly around the eccrine gland is typical. Systemic symptoms and underlying autoimmune disease should be screened. Avoiding cold and keeping extremities warm is the first recommendation for management, as well as smoking cessation. Calcium channel blockers (in particular nifedipine) seems to be the treatment that has been most evaluated in chilblains. However, their effectiveness is not confirmed by all studies. Topical betamethasone is often used but its effect has not been confirmed by randomized clinical trials. Other treatments, such as pentoxifylline, hydrochloroquine and topical nitroglycerin have shown positive effects only in a reduced number of patients. Acupuncture seems to bring a benefit.

Abstract
Hypercalcemia is a potentially life-threatening electrolyte imbalance that is commonly caused by hyperparathyroidism, supplement or medication use, and/or malignancy. Splenomegaly is commonly a non-specific finding, but in the setting of hypercalcemia, may provide diagnostic insight into the underlying pathology and warrant further evaluation. A 70-year-old man presented from his outpatient provider with serum calcium > 15 mg/dL with complaints of one-month fatigue, weakness, poor oral intake, 10 lbs. unintentional weight loss, and periodic confusion noted by his wife. He received an extensive inpatient workup which was non-diagnostic. Splenomegaly was observed on radiographic imaging and reported as "nonspecific". Following discharge, denosumab was required to manage the hypercalcemia. Eventually, a diagnosis of primary splenic lymphoma was made months later. Laparoscopic splenectomy was planned but was advanced to an open laparotomy intraoperatively due to the rapid growth of the neoplasm. Early and close investigation of the spleen is warranted when splenomegaly presents in the setting of hypercalcemia and, as in this case, may prevent significant therapeutic burden.

Abstract
Since it has been recognized that sarcoidosis (SA) is not an exclusive disorder of the lungs but can also affect other organs such as the liver and spleen, efforts have been made to define specific imaging criteria for the diagnosis of the single organ involvement, and the concept has been reinforced that the exclusion of alternative causes is important to achieve the correct diagnosis. Ultrasound (US) is a useful tool to evaluate patients with suspected abdominal SA, such as of the liver, spleen, kidney, pancreas and other organs, showing findings such as organomegaly, focal lesions and lymphadenopathy. While the diagnosis of abdominal SA is more predictable in the case of involvement of other organs (e.g., lungs), the problem is more complex in the case of isolated abdominal SA. The recent use of contrast-enhanced ultrasound and endoscopic ultrasound elastography has provided additional information about the enhancement patterns and tissue rigidity in abdominal SA. Here we critically review the role of US in abdominal SA, reporting typical findings and limitations of current evidence and by discussing future perspectives of study.

Abstract
Sarcoidosis is a multisystemic inflammatory disease of unknown origin characterized by the formation of noncaseating granulomas and accumulation of inflammatory cells. Sarcoidosis most commonly affects the lungs and lymphoid system. However, the liver can also be involved in 50%-65% of cases. On magnetic resonance imaging, sarcoidosis lesions usually present as hypointense lesions on all sequences. However, we present a rare case of nodular liver sarcoidosis presenting with T2 hyperintense lesions. In addition, while most cases of hepatic nodular sarcoidosis present with multiple small hepatic nodules, liver masses of our case are larger than usual. Moreover, this case suggested that when intact vascular structures penetrating liver nodular lesions are observed as in the current case, liver sarcoidosis can be included in a list of differential diagnosis.

Abstract
Involvement of the central nervous system in sarcoidosis is rare; neurosarcoidosis, although unusual, can present as leptomeningitis. The diagnosis is usually difficult because of the vague and broad symptomatology; therefore, a prompt diagnosis should be made, and adequate treatment should be administered to reduce morbidity and mortality.

Mol Med Rep 2017; 15:3350-3354. [PMID: 28339019 DOI: 10.3892/mmr.2017.6380] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2016] [Accepted: 02/23/2017] [Indexed: 11/05/2022] Open
Abstract
Basalt and volcanic ash are natural constituents of the ground surrounding volcanic areas such as Mount Etna. The dust may be daily inhaled by the general population as well as by several types of workers, such as construction workers. In this experiment, we analyzed the potential mutagenic and cytotoxic effects of the materials used in construction industry, excavated from Mt. Etna. Ground basalt (A), volcanic ash (B), mixed basalt and cement (C) and cement (D) were studied with Ames test, for mutagenic assessment and with MMT assay for cytotoxic evaluation. The Ames test revealed that cement (sample D), showed a higher and significant mutagenicity than the samples A, B and C. MTT assay showed that samples C and D had a slightly more negative impact on cell viability than A and B. In conclusion, no particular risks seem to exist for construction industry workers, while the exploitation of cement and cement mixed with basalt seems to be a risk for workers, given the high percentage of silica and iron.
