ABSTRACT
Thyrotropin (TSH)-secreting pituitary adenoma is a very rare disease. In one-quarter of patients suffering from this disease, the pituitary tumor secretes other anterior pituitary hormones. Herein, we report a case of pituitary adenoma with simultaneous secretion of TSH and growth hormone (GH). A 34-year-old female visitied local hospital complaining of sweating, intermittent palpitation, and weight loss of 8 kg within 1 year. The patient had undergone trans-sphenoidal surgery 3 years prior for resolution of a TSH and GH co-secreting pituitary adenoma. She had been administered somatostatin analogue prior to visiting our hospital. The patient's GH levels were suppressed to below 1 ng/mL on the 75 g oral glucose tolerance test, and her basal insulin-like growth factor-I (IGF-I) level was within normal range. Thyroid function tests demonstrated increased levels of both free thyroxine and TSH. Sella-MRI revealed pituitary adenoma at the floor of the pituitary fossa, approximately 2 cm in height. Therefore, she was diagnosed with residual TSH-secreting pituitary adenoma. The patient again underwent trans-sphenoidal surgery and entered complete remission, based on hormone levels and MRI findings.
