Abstract

Traumatic aneurysm is a rare complication of head trauma. Unfortunately, it is rarely recognized until their presence is heralded by delayed deterioration or intracranial hematoma, etc,. Early diagnosis and surgical treatment are most important for good outcome. We recently encountered a patient who developed a pericallosal aneurysm after major trauma. With a high index of suspicion about traumatic aneurysm, brain MRI and MRA were performed. Definitive diagnosis was made by transfemoral carotid angiography, revealing a aneurysm of the right proximal pericallosal artery. The aneurysm was explored through right interhemispheric approch. A $15{\times}15mm$ sized traumatic aneurysmal sac, located in proximal portion of right pericallosal artery was noted. It was dissected from the falx of cerebri and its neck was clipped. The postoperative course was uneventful. Traumatic intracranial aneurysm should be suspected in any patient who deteriorates after the trauma. Early recognition and prompt treatment are warranted in this setting. Definitive surgical treatment of all traumatic intracranial aneurysm is recommended.
