Abstract
-
Traumatic intracranial aneurysm rarely occurs after a head injury. The authors report a case of a 51-year-old man in whom subarachnoid hemorrhage was developed as a result of delayed traumatic aneurysmal rupture of the distal portion of the middle cerebral artery following a minor, closed-head injury. The unruptured aneurysm had been evident on the magnetic resonance image taken two days prior to onset of the subarachnoid hemorrhage. The clinical presentation and possible underlying mechanism are discussed with a review of pertinent literature.
