Coil Embolization of Posterior Inferior Cerebellar Artery Isolated Aneurysms

I read with great interest the article by Tikkakoski et al (1) describing their treatment of an isolated dissecting aneurysm of the left posterior inferior cerebellar artery with Guglielni de-tachable coils (GDCs). I would like to draw the authors ’ atten-tion to two additional articles relating to this subject. One article published in the Journal of Neurosurgery was a case report of an isolated posterior inferior cerebellar artery treated with standard platinum microembolization coils. The lateral medullary syndrome was fortunately avoided in this patient (2). Another case that we previously reported was a pseudoaneu-rysm of the posterior inferior cerebellar artery, caused by a head and neck tumor biopsy, which was treated by proximal occlusion of the posterior inferior cerebellar artery using stan-dard platinum microembolization coils (3). I hope these two additional articles will show that in some situations, isolated aneurysms involving the posterior inferior cerebellar artery need not be occluded with GDCs, but can be treated with more conventional coil devices. However, the authors have achieved an excellent result with GDCs
