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.
起源于鞍内间隙的室管膜瘤极为罕见，在鞍内肿瘤块的鉴别诊断中通常不被考虑。我们回顾文献以进一步提高对这类肿瘤不寻常表现的认识，并呈现一例发生在不常见部位的鞍内囊性室管膜瘤的说明性病例。在我们的说明性病例中，患者有2年垂体功能减退病史，但无头痛或视觉障碍。术前，该病变被认为是垂体大腺瘤。
