The NPV results in our study suggest that unenhanced balanced SSFP MR angiography can be the first-choice imaging method to exclude RAS in patients at high risk of nephrogenic systemic fibrosis. However, when stenosis is found, other imaging modalities are necessary for better estimation.
An isolated dissection of the celiac artery is an extremely rare condition that requires a high level of suspicion to evoke the diagnosis. Once established, the natural course is unpredictable in view of the discrepancies in its management requiring a case-by-case analysis. In this paper, we report an unusual case of spontaneous abdominal pain that was diagnosed with celiac and splenic artery rupture secondary to physical stress. This paper underlines the necessity to maintain a high level of suspicion for arterial dissections and we also review the management plan in such cases.
Invasive aspergillosis is a life-threatening condition of the immunocompromised, with a low occurrence reported in the immunocompetent. Although usually made by invasive methods, its early diagnosis is the cornerstone of a better prognosis as it yields a timely management and thus a lower mortality risk. Mediastinal invasion by Aspergillus is, like any fungal mediastinitis, uncommon and usually results from a hematogeneous or a contiguous spread, a postoperative fungal infection, a complication of a descending necrotizing fasciitis, or from an esophageal perforation. We report a case of a diabetic patient with a previous history of hospitalization 2 months earlier for a COVID-19 infection, otherwise healthy, presenting with an unresolving dorsal pain. A malignancy was expected but further work-up showed in fine a posterior mediastinitis due to Aspergillus fumigatus. Thus, fungal etiologies are to be included as a differential while diagnosing a posterior mediastinitis even in a relatively immunocompetent patient and with no evident route of entry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
