a. Noncontrast head CT image in a patient with sudden right-sided weakness and a recent fall, demonstrated large acute intraparenchymal hemorrhage in the left frontal lobe (arrow). Concurrent head and neck CTA was unremarkable without evidence of large vessel occlusion, AVM, aneurysm, or venous sinus thrombosis.

b, c. Subsequent MRI. GRE (3b) demonstrated a large area of susceptibility in the left frontal lobe consistent with hemorrhage in keeping with head CT findings (arrow). T2/FLAIR (3c) demonstrated vasogenic edema adjacent to the parenchymal bleed (arrow).

d. Axial stroke CTA demonstrated peripheral ground glass opacities in the partially imaged lung apices (arrows), compatible with COVID-19.
