Spectrum of MR imaging findings of sinonasal mucormycosis in post COVID-19 patients.

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.Advances in knowledge:Radiological findings of mucormycosis in post COVID-19 patients show varied patterns of disease involvement and spectrum of imaging features. One should not solely rely on CT imaging to detect the extent of disease. MRI helps in early and accurate detection of invasion into adjacent structures and so helpful in early intervention.
