title: Choroid plexus papilloma of the fourth ventricle.
abstract: A 14 year old girl presented with a 6 months' history of headache with vomiting, ataxia and cerebellar signs. CT and MRI revealed obstructive hydrocephalus secondary to a large fourth ventricular mass which enhanced markedly on contrast administration. Histopathology of the resected mass revealed papillary structures lined by cuboidal cells confirming choroid plexus papilloma.
