This 52-year-old gentleman with uncontrolled diabetes and COVID-19 presented with insidious-onset, progressively worsening bifrontal and retro-orbital headache with loss of vision in both eyes. MRI revealed features of ischemic stroke in the right ACA and posterior watershed territories (a-T2W, b-DWI, c-ADC), complete non-enhancement in right and partial non-enhancement of left cavernous sinus suggestive of thrombosis (d-T1W axial post-contrast, yellow arrows), and non-enhancing mucosa lining the nasal cavity and maxillary sinuses, extension of disease into the orbits (yellow arrow, right orbit) with a bifrontal abscess (red arrow) (e-T1W coronal post-contrast) suggestive of aggressive invasive infection.

Surgical exploration and histopathological correlation revealed rhinocerebral Mucormycosis with brain abscess
