Extradural hematoma due to rupture of post-traumatic pseudoaneurysm of the middle meningeal artery is a very rare clinical entity. Only fourteen such cases have been reported in the literature. A 52-year-old, right-handed Mexican male was admitted with motor aphasia and right-sided signs but no history of unconsciousness. He had been struck by an automobile almost 24 hours earlier. His neurological signs appeared shortly thereafter. A left temporoparietal linear fracture of the skull was recognized as well as a fracture of the right knee. Angiography revealed a lenticular parietal avascular area with depression of the middle cerebral artery and a shift of the anterior cerebral artery. An aneurysm was observed on the left middle meningeal artery below the skull fracture. At craniotomy a large extradural hematoma was evacuated and the aneurysm removed. The patient had a complete recovery.
外伤性脑膜中动脉假性动脉瘤破裂所致硬膜外血肿是一种非常罕见的临床病症。文献中仅报道过14例此类病例。一名52岁、惯用右手的墨西哥男性因运动性失语和右侧体征入院，但无昏迷史。他在近24小时前被汽车撞击。此后不久出现神经体征。头颅X线片显示左侧颞顶部颅骨线性骨折以及右膝骨折。血管造影显示一个豆状顶叶无血管区，大脑中动脉压低，大脑前动脉移位。在颅骨骨折下方的左侧脑膜中动脉上观察到一个动脉瘤。开颅手术时清除了一大块硬膜外血肿并切除了动脉瘤。患者完全康复。
