脳血管撮影中に造影剤のExtravasationを認めた巨大脳動脈瘤の1例

Extravasation of Contrast Medium Demonstrated during Cerebral Angiography in the Giant Aneurysm: Case report

I．はじめに

　脳動脈瘤患者の脳血管撮影中に造影剤のextravasationを認めた報告は数多い^{3,4,10，13）}．最近では脳血管撮影だけでなく，CTscanにてextravasahonを碓認した報告も散見される^5）．筆者らは最近，脳血管撮影中に再破裂を来たし，脳血管撮影とこれにひき続いて施行したCT scanの両者において造影剤のeMravasationを認めた巨大脳動脈瘤の興味深い1例を経験したので報告する．

The authors report a case of giant aneurysm in which extravasation of contrast medium was demonstrated during cerebral angiography and confirmed by com-puted tomography.

A 33-year-old man suddenly lost consciousness and vomited frequently. Three hours later, he was admitted to our hospital in semicomatose state with left hemiplegia. Within two hours after admission, plain CT scan, enhanced CT scan, left carotid angio-graphy and post-angiographic CT scan were perform-ed. CT scan showed marked subarachnoid hemor-rhage, left temporal intracerebral hematoma and oval mass which was remarkably enhanced in the left Sylvian fissure.
