The following case concerns a young female patient with spontaneous subarachnoid hemorrhage (SAH) due to a ruptured aneurysm originating at a non-fused, fenestrated proximal segment of the basilar artery. The aneurysm was treated with endovascular coil embolization which resulted in complete exclusion, and the patient showed a complete clinical recovery. A second aneurysm originating from the left internal carotid artery (ICA) was diagnosed during the follow-up and was treated in a separate session using a flow diverter stent. Three additional cases of ruptured aneurysms of non-fused basilar arteries are presented at the end of the discussion. Basilar artery fenestration with associated aneurysm formation is the main topic of this chapter.
