Craniopharyngioma intrinsic to the third ventricle

The case of a third ventricular craniopharyngioma in a 57-year-old woman is reported. This lesion is rare, having been previously identified in only eight adults. Intraventricular craniopharyngioma is also unusual in that it is not associated with tumoral calcification or cyst formation, as is frequently seen with the more common suprasellar craniopharyngioma. The role of computed tomography scanning in the diagnosis of this tumor is presented and discussed.
