Thickening of the pituitary stalk: a finding suggestive of intrasellar tuberculoma? Case report.

We describe the case of a patient with an exclusively intrasellar mass, disclosed because of a left sixth nerve palsy and headaches. No other manifestation of disease, namely, endocrinological, was present. The lesion was approached transsphenoidally, and the pathological examination revealed a tuberculoma. Complete removal was achieved, and the patient started postoperative antituberculous therapy. In some circumstances, thickening of the infundibulum and the pituitary stalk could preoperatively suggest the diagnosis of hypophysial tuberculoma.
