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.
一名63岁女性在进行脑血管造影以评估右额凸部和岩骨脑膜瘤4天后，因颅内肿瘤内及肿瘤周围出血伴脑疝形成而出现左侧偏瘫。脑血管造影操作可能导致了肿瘤水肿和颅内出血，因为入院时的计算机断层扫描显示右额凸部脑膜瘤与出血前相比密度略低。已知注射造影剂会引起涉及微循环衰竭和与脑肿瘤相关的血脑屏障功能障碍的并发症。因此，造影剂可能在脑血管造影后对脑膜瘤产生了影响。
