An 84-years-old female patient was proved for COVID-19 infection after one week of cough and mild fever. She presented to the emergency unit with a suddenly disturbed level of consciousness. [A] Chest CT examination (lung window) revealed small right basal sub-pleural ground-glass patches of COVID-19 infection (red square). [B, C] Urgent non-contrast brain CT revealed bilateral high frontoparietal cortical and sub-cortical heterogeneous mixed hypo and hyper-dense areas (green and red arrows) … The initial diagnosis was bilateral hemorrhagic infarctions. An initial non-contrast MRI examination was performed. They express heterogeneous hypointense signals in T1-WI [D] and mixed iso and hyperintense signals in T2-WI [E] and FLAIR-WI [F] (yellow arrows). Positive diffusion restriction was noted with cortical bright DWI signal [G] and low ADC value in ADC mapping [G] (blue arrows). Hemorrhagic transformation was evidenced by positive SWI signal blooming [H] (violet square) … Hyper-acute hemorrhagic transformation was diagnosed
