ABSTRACT |
Traumatic intracranial aneurysm is a rare complication of severe head injury. Compared with traumatic aneurysm involving the supraclinoid portion of the internal carotid, distal anterior cerebral, and middle cerebral artery, traumatic aneurysm located in the posterior fossa is extremely rare. The authors present a case of traumatic aneurysm involving the posterior inferior cerebellar artery after a severe closed head injury. The patient presented with intraventricular hemorrhage, but there was no evidence of skull fracture. Cerebral angiography revealed a large aneurysm located in the posterior inferior cerebellar artery; repeated angiography demonstrated an enlarged aneurysm following sudden clinical deterioration fifteen days after initial trauma. The PICA was embolized with a tungsten and platinum coil and far lateral suboccipital craniectomy was performed for decompression. Pathologic findings of the resected aneurysm were compatible with a pseudoaneurysm. |
