Acute and subacute lobar hemorrhage

Noncontrast head CT shows acute right parietal ICH (A). T2* susceptibility-weighted sequence on MRI performed one day later shows an acute ICH in the right frontal and parietal hemisphere (B) as well as a subacute hemorrhage in the left occipital lobe (thick arrow) and chronic ICH in right inferior parietal lobule (C; arrow). In addition, multiple microbleeds at cerebral corticomedullary junctions (B, C) are consistent with cerebral amyloid angiopathy.
