Intrinsic III ventricle craniopharyngioma.

A case of intrinsic III ventricle craniopharyngioma in an 11-year-old girl is presented. Only five cases in children have previously been reported in detail. The intraventricular location of a craniopharyngioma originates from ectopic remnants and causes intracranial hypertension without hormonal or neurological disorders. The tumor was safely removed by the transcallosal approach, and we confirmed that the floor of the III ventricle was intact.
