Lobar hemorrhage in cerebral amyloid angiopathy

Acute superficial lobar hemorrhage in the left frontal lobe seen on computed tomography scan in a patient with cerebral amyloid angiopathy (A). Flair magnetic resonance image performed one week later shows the high signal intensity of subacute hemorrhage with surrounding edema extending into the subcortical white matter (B). Hemorrhage (now low signal intensity consistent with hemosiderin) and edema are mostly resolved on a three-month follow-up study (C).
