Spontaneous or iatrogenic? Postoperative pseudo aneurysm in craniopharyngioma: Case report

Caniopharyngiomas pose significant surgical challenge because of their location and close proximity to major neurovascular structures. Early and delayed vascular complications associated with Craniopharyngioma and its surgery have been documented. Various mechanisms have been postulated for the origin of aneurysms in Craniopharyngioma. Though the surgery and minor injuries to the vessel wall might predispose the aneurysm formation, exact mechanism and relation is lacking. We report a case of a psedoaneurysm of the distal ACA AT A2`-A3 junction in a case of cystic Craniopharyngioma who presented with rupture, 2 weeks after primary surgery. Insight into the probable causes of aneurysm formation and its subsequent rupture and management have been described.
