Case 2:63-year-old woman A,B) An aneurysm of the basilar artery apex can be seen originating from the sac of the superior cerebellar arteries and the right posterior cerebral artery. C) Placement of a Neuroform2 stent with proximal end in the basilar artery and the distal end in the right posterior cerebral artery. D,E) partial embolization of the aneurysm with 6 coils for a total of 115 cm. The proximal portion of the lesion was not embolized to avoid occluding the origin of the superior cerebellar arteries. The posterior cerebral artery maintains stent patency. F) MR angiography follow-up after six months shows the aneurysm partially thrombosed and the origin of right posterior cerebral artery.
