A 13-year-old girl sufferring from a car accident presented with a symptom of oculomotor
nerve palsy. A CT scan revealed diffuse SAH in the suprasellar cistern, cisterna ambiens
and interpeduncular cistern. MRI showed contusion of the left cerebral peduncle and
a flowing void signal in front of the left cerebral peduncle. Cerebral angiography
revealed a bilobulated aneurysm on the P1-P2 junction of the left posterior cerebral
artery. Endovascular treatment was performed, with coil packing within the aneurysm
and occlusion of the parent vessel. There were no neurological deficits and no recurrence
of the aneurysm on follow-up studies. Endovascular embolization of traumatic posterior
cerebral artery aneurysm is a safe and effective therapeutic approach.
