A 46-year-old female patient presenting after 2 weeks of COVID-19 infection with AIFS, histopathological proven to be mucormycosis. A, B axial T2W MRIs revealed loss of the signal void in the cavernous segment of the left ICA denoting thrombosis. C coronal T2WI, D coronal contrast enhanced T1W MRI showed left superior ophthalmic vein thrombosis (orange arrow), enhancing left intra-orbital soft tissue infiltration (white arrow), mucosal thickening of left maxillary sinus and left inferior nasal turbinectomy. E, F axial non-contrast enhanced T1W MRIs with fat suppression showed thrombosis of the petrous and cavernous segments of the left ICA. G, H axial contrast enhanced T1W MRIs with fat suppression showed heterogenous enhancement of the left ICA thrombosis. I DW MRI, J ADC map revealed mild restricted diffusion at the left ICA thrombosis
