title: [Hypertensive putaminal hemorrhage with extensive subarachnoid hemorrhage presenting extravasation of contrast material during angiography: case report].
abstract: The authors describe a case of hypertensive putaminal hemorrhage with extensive subarachnoid hemorrhage. On admission, the patient aged 71 presented right-sided motor weakness. CT scan on admission revealed left putaminal hemorrhage with extension into the ipsilateral thalamus and lateral ventricle as well as into the subarachnoid space of the suprasellar, ambient, interhemispheric and contralateral sylvian cisterns. To exclude vascular lesions, left carotid angiography was performed just after admission. The lateral view was unremarkable, but the anterior-posterior view demonstrated extravasation of contrast material from the left lateral lenticulostriate artery. The angiographic sylvian point was shifted to the lateral side. No abnormal vessels were revealed. CT scan after angiography showed exacerbation of both intracerebral and subarachnoid hemorrhages, but the consciousness level was unchanged. CT-guided stereotactic aspiration of the hematoma was performed 4 days after the onset, but failed to remove much hemtoma. The patient died of aspiration pneumonia 9 days after onset. The authors emphasize that extensive subarachnoid hemorrhage in cases with hypertensive putaminal hemorrhage may be an important finding which indicates high risk of rebleeding.
