    Abstract:
    A rare case of sellar chordoma occurring in a 67-year-old woman who survived for more than 10 years is presented. Clinical signs and symptoms masqueraded as a non-functioning pituitary adenoma with visual disturbance and hypopituitarism. Initial computed tomography (CT) showed an intrasellar mixed dense mass with suprasellar extension, accompanied by non-homogeneous contrast enhancement. Partial removal of the mass was accomplished via right fronto-temporal craniotomy. Histological examination revealed a typical chordoma with no malignancy. After postoperative irradiation, the patient was discharged with clinical improvement. Serial CT and magnetic resonance imaging 8 years after treatment disclosed a regrowth of the intrasellar lesion, which extended to the sphenoid sinus and clivus, accompanied by non-homogeneous contrast enhancement. The patient underwent subtotal removal of the recurrent tumor through a sublabial transsphenoidal approach. Histological examination confirmed the previous diagnosis. Immunohistochemical study demonstrated positive cytoplasmic expression of vimentin, epithelial membrane antigen, keratin and S-100 protein, in contrast with a lack of appearance of carcinoembryonic antigen. After reoperation, she completely recovered and has survived for more than 10 years with good quality of life.
