Amnesia due to spontaneous haemorrhage into a colloid cyst

Abstract

Anterograde amnesia is a recognised complication of colloid cyst excision, occurring usually as a result of forniceal injury. However, spontaneous amnesia due to intra-cyst haemorrhage prior to excision has not been reported previously. We report such a case in which amnesia completely resolved following endoscopic cyst excision.
