title: [Pseudoaneurysm of the cortical artery associated with chronic subdural hematoma--a consideration on traumatic middle cerebral artery aneurysm].
abstract: A 62-year-old man was admitted to our hospital, since chronic subdural hematoma was showed after he complained of mild headache and nausea. Two years ago he had head trauma at the left parietal region after drinking. On admission there was no paresis and mild choked disc is detected. Computed tomography with contrast enhancement showed abnormal enhancement and left chronic subdural hematoma. Cerebral angiography showed an aneurysm of the angular artery. Operation was done and the aneurysm was trapped. Aneurysmal wall was histologically a pseudoaneurysm. Post-operative result was good. We considered the relationship between the cortical pseudoaneurysm and chronic subdural hematoma. We reviewed the traumatic middle cerebral artery aneurysm in the literature, 56 cases.
