A rare case of choroid plexus papilloma in the third ventricle is presented. A 19 year old male patient was admitted to our hospital for further examination of a head injury. On admission, he was asymptomatic. CT and MRI showed a homogeneous mass extending from the third ventricle to the right lateral ventricle. The right lateral ventricle was slightly enlarged. Craniograms showed calcification above the sella turcica. Cerebral angiograms disclosed a tumor stain fed by the right medial posterior choroidal artery in the third ventricle. Anterior transcallosal approach was chosen for the extirpation of the tumor. Histological study revealed choroid plexus papilloma. The postoperative course was uneventful.
