Intrasellar ependymoma: Clinical, imaging, pathological, and surgical findings

Ependymomas arising in the intrasellar compartment are extremely rare and most often are not included in the differential diagnosis of an intrasellar tumor mass. We review the literature to further advance awareness regarding unusual presentations of this type of tumor and present an illustrative case of an intrasellar cystic ependymoma that developed in an uncommon location. In our illustrative case, the patient had a 2 year history of hypopituitarism, but no headaches or visual disturbance. Preoperatively, the lesion was thought to be a pituitary macroadenoma.
