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.
