Abstract: | An intracranial saccular aneurysm is not commonly diagnosed in a patient with head injury. We present a patient with a history of minor head trauma and a CT scan of the brain revealing minimal subarachnoid hemorrhage 17 days prior to admission, complaining of severe headache, dysarthria and focal right limb seizures 3 hours prior to admission. A traumatic aneurysm was suspected based on clinical history and radiological findings including hematoma in the falx region on a CT scan of the brain and an aneurysm of the pericallosal artery on magnetic resonance angiography and four-vessel cerebral angiography. However, at craniotomy, an intracranial non-traumatic saccular aneurysm at the bifurcation of the pericallosal artery was found. The patient recovered fully after successful clipping the aneurysm. |
