[An unexpected sella turcica tumor].

isual disturbances and hypopituitarism are not exclusive ymptoms of pituitary macroadenomas. Other tumors clinially behaving as macroadenomas may occur in the sellar rea. The most common of such tumors include cranioharyngioma, Rathke pouch cyst, and meningioma.1 The ase of a female patient in whom a pituitary macroadenoma as initially suspected but who was finally diagnosed with nother sellar tumor is reported below. This was a 49-year-old female patient born in the Philipines with a history of hypertriglyceridemia treated with emfibrozil 900mg/day and high blood pressure treated ith indapamide 2.5mg/day. She was referred to our linic by her primary care physician for an impaired thyoid function in two consecutive laboratory tests showing ecrease free tetraiodothyronine (T4) levels and normal hyroid-stimulating hormone (TSH) levels (first laboraory tests: TSH 3.26 IU/mL and free T4 0.50 ng/mL; econd laboratory tests: TSH 2.74 IU/mL and free T4 .60 ng/mL; normal ranges were 0.465--4.68 IU/mL for SH and 0.78--2.19 ng/dL for free T4 respectively). Patient eported a self-limited episode of galactorrhea and mastoynia 8 years before. She had been examined in her country, ut had no medical reports, and stated that no cause had een found. In the past 2 years, the patient had experinced very severe asthenia, facial edema, and amenorrhea. he was also being monitored at the ophthalmology departent for decreased visual acuity. A computed campimetry erformed revealed bitermporal hemianopsia, and the ophhalmologist had therefore requested magnetic resonance maging (MRI) which had not been performed yet. Facial dema, particularly of the eyelids, was conspicuous. The hyroid gland could be palpated, but no nodules were felt. here were no other remarkable findings in the physical xamination or galactorrhea. A pituitary macroadenomawas uspected, and repeat measurements of pituitary basal horones and assessment of MRI were therefore decided. MRI
