title: Aggressive choroid plexus papilloma.
abstract: A young woman, who was initially treated for an Arnold-Chiari malformation, was found 7 years later to have a posterior third ventricular tumor. A superior cerebellar approach allowed total resection of the mass, which was an aggressive choroid plexus papilloma. The patient was treated with whole cerebrospinal axis radiation. There is no clinical or computed tomographic evidence of recurrence after 4 years. The literature is reviewed and a discussion of aggressive choroid plexus papilloma (carcinoma) is presented.
