大脳縦裂部急性硬膜下血腫の3例

Three Cases of Acute Interhemispheric Subdural Hematoma

I．はじめに

　外傷性硬膜下血腫は，大部分，大脳半球穹窿部に起こり，大脳縦裂部の報告は非常に稀である．当科で経験した急性硬膜下血腫は1977年7月より1986年4月までに48例であり，大脳縦裂部血腫は3例（6％）であった．今回われわれはこの3例の外傷性大脳縦裂部急性硬膜下血腫について，若干の文献的考察を加えて報告する．

Traumatic acute subdural hematomas over the con-vexity of the cerebral hemispheres are often encoun-tered, but acute interhemispheric subdural hematomas are rare. Fourty-eight cases of acute subdural hemato-mas was admitted to our hospital between 1977 and 1986, and three cases of them (6%) were located in the interhemispheric subdural space. In this paper, these three cases are reported with 20 documented cases.

Case 1 : an 81-year-old female was admitted to our hospital because of headache, nausea and vomitting. She hit her occiput a week ago.
