A case is reported of a cystic craniopharyngioma involving the floor and walls of the third ventricle. Pronounced anterograde and retrograde amnesia were documented preoperatively by formal testing. Rapid improvement in both new learning capacity and remote memory occurred after percutaneous twist drill drainage of the cystic portion of the tumour. The relevance of these observations to the amn...

These tumors are located close to the visual apparatus, hypothalamus, pituitary stalk, 3rd ventricle, and vasculature from the circle of Willis. The proximity of the tumor and its adherence to these critical structures makes complete microsurgical removal without neurological deterioration difficult [2]. Craniopharyngioma is often associated with cystic components [3]. Although these tumors are...
