ABSTRACT
Background: Sinonasal mucormycosis is a quickly progressing and lethal fungal disease which showed an increased incidence in COVID-19 patients in the Indian population during the second wave of the pandemic. The objective of this study was to study the various sinus areas affected and the imaging findings of the disease. Method(s): The imaging records of patients with sinonasal mucormycosis during the second wave of the COVID-19 pandemic were reviewed and analysed for whom computed tomography (CT) and/or magnetic resonance imaging (MRI) images had been performed. Result(s): Of the 65 patients, 6.1% had single sinus involvement, and 93.9% had multiple sinus involvement, and out of latter, 91.8% had bilateral sinuses affected by the disease process. A total of 49.2% patients with sinus involvement had erosions of the sinus walls. A total of 35.4% patients had only sinonasal mucormycosis, 38.5% patients had rhino-orbital mucormycosis, 4.6% patients had rhino-cerebral mucormycosis and 16.9% patients had rhino-orbitocerebral mucormycosis. The pterygopalatine fossa was affected in 26.2% patients. A total of 9.2% patients had cavernous sinus thrombosis. A total of 12% of the cases had infarction in the cerebral hemispheres. Conclusion(s): In a setting of sinonasal mucormycosis, especially in the immuno-compromised and with those infected with COVID-19, cross-sectional imaging can assess the presence and extent of the disease and helps plan its medical and surgical management.Copyright © 2023, The Author(s).
ABSTRACT
Background. Postponed coronavirus infection (COVID-19), accompanied by an immunosuppressive state and associated with the risk of secondary diseases such as mucormycosis. Diabetes mellitus is an independent risk factor for both severe COVID-19 and mucormycosis. Aims - our aim was to experience the diagnosis and treatment of rhino-orbitocerebral mucormycosis in post-COVID-19 patients. Materials. A single-center, observational, non-randomized, cohort comparative study was conducted. We assessed the clinical features, risk factors, diagnosis and outcomes of mucormycosis among recovered COVID-19 patients with hospitalisation in the otorhinolaryngology department of the Samara State Medical University Clinics, Samara, from September-December 2021. CT examinations were performed on Revolution EVO CT scanner (GE, Russia) and MRI on Aera MR scanner 1.5 T (Siemens, Germany). Materials for microbiological and histopathological examination were taken from all examined patients intraoperatively. Results. The experience of diagnosing and treating rhinoorbitocerebral mucormycosis in patients after a new coronavirus infection was analyzed, the influence of the complex use of radiation diagnostic methods, histopathological and microbiological methods on the development and effectiveness of mucormycosis treatment was determined. Conclusions. The effectiveness of disease management directly depends on the early initiation of etiotropic treatment, while the role of complex radiological diagnostics, histopathological and microbiological methods is important for early confirmation of the fungal etiology of the disease.Copyright © 2022 Izdatel'stvo Meditsina.

ABSTRACT
PURPOSE: To report two cases of COVID-19 under treatment with a corticosteroid; in one case rhino-orbitocerebral mucormycosis and in another one rhino-orbital mucormycosis developed. CASE PRESENTATION: A 40-year old woman and a 54-year old man with severe COVID-19 underwent corticosteroid therapy for immune-related lung injuries. The first case presented with a bilateral visual loss and complete ophthalmoplegia of the right eye. The second case presented with vision loss, proptosis, orbital inflammation, and complete ophthalmoplegia on the left side. Histopathologic, nasal endoscopic examinations, and radiologic findings confirmed mucormycosis in both patients. The patients denied orbital exenteration and were managed with systemic amphotericin B and daily endoscopic sinus debridement and irrigation with diluted amphotericin B. Because of the intracranial space involvement, the first case died. The second case was successfully managed surgically and medically. CONCLUSION: Rhino-orbital/cerebral mucormycosis may be developed in COVID-19 patients under treatment with corticosteroid, and requires prompt diagnosis and management.
