Cerebral amyloid angiopathy associated with massive intracerebral hemorrhage.

Characteristic computed tomographic, clinical and pathologic features are discussed in two patients with cerebral amyloid angiopathy (CAA) associated with massive intracerebral hemorrhage. Amyloid angiopathy should be considered in any elderly patient in whom intracerebral hemorrhage occurs at an atypical site. Cortical involvement, multiplicity of hemorrhages, bilaterality, and repeated episodes should further arouse diagnostic suspicion. Clinical management is confined to prevention of systemic hypertension.
