[Craniopharyngioma in the third ventricle].

A rare case of craniopharyngioma wholly located within the third ventricle is reported. A 55-year-old female was admitted to our hospital with the complaints of headache and fever of unknown origin. Neurological findings were normal. Computed tomography (CT) scan showed homogeneously enhanced mass lesion within the third ventricle. Axial and coronal CT scans disclosed an intact suprasellar cistern. The tumor was completely removed using an interhemispheric trans-lamina terminalis approach. Histological diagnosis was squamous cell type of craniopharyngioma. Post-operative diabetes insipidus was well controlled, and irradiation of 50 Gy was performed. Craniopharyngioma located entirely in the third ventricle was reviewed, and etiology, clinical feature and treatment were discussed.
