Three cases of pituicytoma with a review of the literature and insight into a rare variant of ependymal pituicytoma.

Abstract

Pituicytomas are rare tumors of the pituitary gland arising along the distribution of the neurohypophysis in adults. Due to their rarity and varied radiological appearances, they are difficult to diagnose preoperatively. This is a small case series of 3 cases of pituicytoma, wherein, we highlight a rare case of ependymal pituicytoma in a 46-year-old man who presented with progressive loss of vision on both eyes. The patient presented with a suprasellar mass that on histopathological examinations was diagnosed as ependymal pituicytoma. Both histopathological and radiological diagnostic challenges are discussed of this rare case along with the other two cases of pituicytoma for comparison.
