Giant intrasphenoidal aneurysms of the ICA are extremely rare and potentially disastrous because of the risk of fatal epistaxis. Even more unusual is the fissuring of the aneurysm, which may be the forerunner of rupture. Indeed, the risk of rebleeding is high, approximately 20% to 50% in the first 2 weeks.1 The present case was successfully treated, although recent, repeated epistaxis looked like an unpromising outcome.
