Özet: Introduction: Amidst this SARS-COV2 pandemic, epidemic outbreak of Mucor-mycosis is being noted in various parts of the World especially in India of which commonest being rhino-orbito-cerebral mucor-mycosis. Suspected mucor-mycosis requires urgent intervention, because of often rapidly progressive and destructive nature of the infection. The purpose of our study is to describe the radiological feature observed in the COVID-associated mucormycosis.Aim: To obseve the benefits of CT Scan Vs MRI in management of Mucormycosis.Methods: We prospectively observed the plain CT and Gadolinium contrast enhanced MRI of Paranasal sinuses, orbit and brain for 20 patients with clinical suspicion of rhino-orbital-cerebral mucormycosis.Results: In MRI, all the patients had Hypointense lesion in T1W Fig, but the signal intensity characteristics of T2W I variable with most common being hypo-intensity (50%) followed by hetero-intense (30%) and hyper-intense (30%). In Post-contrast enhancement pattern, 15% of patient had non-enhancement, while 30% had heterogenous and peripheral enhancement each and 25% had homogenous enhancement. The most common paranasal sinus to get involved is maxillary sinus (90%) and least common being frontal sinus (30%). Orbit (65%) was the commonest extra-sinus site to get involved. In 10% and 5% of patient cavernous sinus thrombosis and internal carotid artery thrombosis was noted respectively. 30% of patient had cerebral parenchyma involvement. For 30% of patient osseous involvement was noted in CT scan.Conclusion: Rhino-orbital-cerebral mucor-mycosis is an acute and fatal infection with higher mortality rate due to its rapidly spreading nature. To decrease the mortality rate, early diagnosis and intervention is needed. MRI prevails over CT scan in all the aspects (perineural, base of skull, intracranial and intra-orbital changes detection) except for osseous involvement for which CT scan is needed.
