Medical literature describing intracranial aneurysms and their cause, effect, and treatment in adults is plentiful. However, aneurysms of the posterior fossa occurring in children are not common, and those specifically of the posterior inferior cerebellar artery in children are indeed a rarity.1,2 McDonald and Korb2 reviewed the literature of intracranial aneurysms prior to 1939, and of the 1,125 cases reviewed found 251 (22%) to be in the vertebrobasilar system. Eight of these 251 (0.7%) were of the posterior inferior cerebellar artery, and only one of the eight occurred in a child. This was a 6-year-old child reported by Haike and Lewy.3 Hermann and MacGregor4 and Newcomb and Munns5 published case reports of aneurysms in children neither of which occurred in the posterior fossa. Carmichael,6 in 1950, reviewed 267 intracranial aneurysms and found only one occurring in a child. Jane1 reported a large unruptured
