Abstract
- The traumatic intracranial aneurysm within the posterior cranial fossa is extremely rare. The case of a 18-year-old boy who developed an saccular aneurysm lately in the posterior fossa after a blunt head injury is reported. Repeated follow-up angiography demonstrated an saccular aneurysm at the junction of vertebral artery and posterior inferior cerebellar artery. Early brain MRI disclosed neither aneurysm nor mass. Late brain MRI revealed a partially thrombosed saccular aneurysm at the cerebello pontine angle. Follow-up MRI and angiography is recommended if traumatic aneurysm is suspected.
