  • Look Inside

Traumatic cerebral aneurysms occupy less than 1%in all cerebral aneurysms and the onset usually occurs two to three weeks after the head injury.

The authors present a case revealing an aneurysm-like shadow at the supraclinoid portion of the internal carotid artery immediately after the head injury.

A 45-year-old man was admitted in a semi-comatose state, with bleeding from the nose and the ear. He presented anisocoria, with the left pupil larger, and absence of light reflex of the pupil.

Roentgenographic examinations revealed fractures of the skull, the left radius, and the pelvis.
