Traumatic basilar-cavernous fistula associated with aneurysm of basilar artery.

A 19-year-old boy's left temporal region was struck by a screwdriver, he immedietly lost consciousness for several minutes, when he came back he had a serious headache and obvious left ptosis. CT scanning showed an intracranial air accumulation and obvious traumatic subarachnoid hemorrhage (SAH), 2 weeks later magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) showed a traumatic aneurysm in basilar artery. Digital subtraction angiography (DSA) was performed 4 weeks later, revealing a basilar-cavernous fistula and a saccular aneurysm of the basilar artery in his head. After the patient was treated with endovascular embolization therapies twice and with mechanical detachable spiral (MDS) for 5 months the patient was cured finally.
