Recurrent ectopic craniopharyngioma

Abstract

A 66-year-old woman developed an asymptomatic mass in the right frontal lobe 5 years after undergoing a right frontal craniotomy and removal of a craniopharyngioma. The mass progressively enlarged over the next 3 years, during which time it became multiloculated and partially cystic. Repeat craniotomy was performed 8 years after the original operation, at which time the mass was found to be an ectopic craniopharyngioma. The lesion probably resulted from seeding of tumour cells along the surgical tract at the time of the initial surgery.
