Pituicytoma

A rare glial tumor originating from pituicytes, the specialized glial cells of the neurohypophysis, characterized by a sellar or suprasellar mass manifesting with clinical signs secondary to mass effect. Typical manifestations are visual disturbances, headaches, and hypopituitarism. Pituicytomas are low-grade tumors, and prognosis is good after total resection.
