Abstract

Hematomas caused by ruptured traumatic pseudoaneurysms of the middle meningeal artery (MMA) usually present with extradural hematomas, whereas intradural intraparenchymal hematomas are extremely rare. We report a case of traumatic pseudoaneurysm of the MMA giving rise to an intracerebral hematoma after head trauma. A 70-year-old man suffered a massive intracerebral temporoparietal hemorrhage after a head injury. CT angiogram of the brain revealed a large hematoma in the right middle cranial fossa extending to the right sylvian fissure. Cerebral angiogram also revealed a pseudoaneurysm of the MMA, which was successfully treated surgically. Although traumatic MMA pseudoaneurysm producing intracerebral hematoma (ICH) is rare, it should be considered as a possible cause of intracerebral hematoma.

摘要

由脑膜中动脉(MMA)外伤性假性动脉瘤破裂引起的血肿通常表现为硬膜外血肿,而硬膜内脑实质内血肿极为罕见。我们报告一例MMA外伤性假性动脉瘤在头部外伤后导致脑内血肿的病例。一名70岁男性在头部受伤后发生大量颞顶叶脑内出血。脑部CT血管造影显示右侧中颅窝有一个大血肿,延伸至右侧外侧裂。脑血管造影也显示MMA假性动脉瘤,经手术成功治疗。尽管外伤性MMA假性动脉瘤导致脑内血肿(ICH)很罕见,但应将其视为脑内血肿的可能原因之一。
