title: Intracranial hemorrhage associated with convexity meningioma after cerebral angiography--case report.
abstract: A 63-year-old female developed left hemiparesis caused by intracranial intratumoral and peritumoral hemorrhage with cerebral herniation 4 days after cerebral angiography to evaluate right convexity and petrosal meningiomas. The cerebral angiography procedure may have caused the tumoral edema and intracranial hemorrhage because computed tomography on admission revealed the right convexity meningioma as slightly low density compared to before the hemorrhage. Administration of contrast medium is known to cause complications involving microcirculatory collapse and blood-brain barrier dysfunction associated with brain tumors. Therefore, the contrast medium may have affected the meningioma after cerebral angiography.
