―症例―Balint症候群を呈したAmyloid angiopathyによる両側頭頂葉皮質下出血の1例

A Case of Multiple Cerebral Hemorrhage Related to Cerebral Amyloid Angiopathy

I．はじめに

　cerebral amyloid angiopathy（以下CAA）は老年者や遺伝性の若年性脳出血の原因として近年注目されている．しかし，その本態は不明な点が多い．

　われわれはBalint症候群を呈し，CAAが原因と考えられた脳内血腫の1例を経験したので若干の文献的考察を加え報告する．

A case of multiple cerebral hemorrhage in the bilateral parietal lobes related to cerebral amyloid angiopathy (CAA) is reported. A 66-year-old man was admitted to our hospital because of headache and vomiting on Feb. 21, 1983. He had no history of hypertension, diabetes mellitus, recent head injury, or dementia. Four clays prior to admission, he had behaved as if he were blind, but, had denied any blindness. On examination, he was confused and disoriented.
