title: June 1999--22 year old female with intraventricular mass.
abstract: A 22 year old female presented with a single seizure. CT scan and craniotomy demonstrated an intraventricular papillary tumor with histologic and immunohistochemical features indicative of a choroid plexus carcinoma. Even though the occurrence of this neoplasm is exceptional beyond childhood, pathologists should considered a malignant choroid plexus tumor when postulating the differential diagnosis of intraventricular papillary neoplasms in adults.
