A 79-year-old female presented with subarachnoid hemorrhage due to rupture of a rare true posterior communicating artery(PCoA)aneurysm and with poor general condition. Endovascular therapy was performed in the chronic stage. Right carotid angiography just before embolization demonstrated unusual multiple aneurysms of the internal carotid artery(ICA)-PCoA complex. Superselective an-giography and aneurysmography using microcatheter revealed two separate aneurysms arising from the PCoA and the ICA-PCoA junction. Endosaccular embolization using Guglielmi detachable coils (GDCs)was successfully performed for both aneurysms and complete occlusions were achieved with the PCoA fully patent. Embolization with GDCs is a good alternative to surgical clipping for PCoA aneurysm after careful evaluation of superselective angiography.
