A 39-years-old female patient, with a history of COVID-19 infection two months ago, complained of dizziness. Partial improvement was achieved on supportive treatment. MRI was requested because of persistent symptoms. No previous history of neurological diseases. The neurological examination was free. Multiple small cortical and to a lesser extent sub-cortical as well as deep white matter lesions are seen in the right frontoparietal lobes (yellow arrows) showing: T2 hyper-intense signal [A–C], FLAIR hyper-intense signal [D–F] without DWI restriction [G–I]. [J, K] Sagittal FLAIR weighted images are demonstrating the lesions. [L] Coronal chest CT (lung window) 2 months ago showed a right apical sub-pleural ground-glass patch of COVID-19 infection. Symptoms alleviated after a short course of steroid therapy with resolution of MRI lesions… both, the clinical context and cortical involvement, suggested the possibility of post-COVID vasculitis rather than demyelinating diseases
