Transsphenoidal resection has been well accepted as the most suitable treatment for TSH-secreting pituitary adenomas. However, due to its rare incidence, appropriate clinical practice for the postsurgical management remains to be accumulated. We report here a case of a 53-year-old male patient diagnosed to have a Thyroid-Stimulating Hormone (TSH)-secreting pituitary adenoma. The tumor was successfully removed by transsphenoidal resection, and the histological examination elucidated a pituitary adenoma with TSH positive staining. The serum level of TSH restored to normal after 3 months and eMRI detection demonstrated no sign of recurrence 12 months after the surgery. Serum levels of T3, T4, FT3, FT4 and TSH were all normal during a 42-month follow-up. While notably, 8 days after the surgery, the patient underwent severe hyponatremia (lowest to 113 mmol/l Na+) with lethargy, and the serum level of Na+ was recovered to 134 mmol/l on day 11 after emergent treatment of hypertonic saline and high salt food. This case reveals the risk of postoperative hyponatremia for thyrotrophinoma patients even with a successful resection of the tumor, which emphasized the significance of combination treatments, including 1-2 weeks prolonged hospitalization, to avoid the severe threats to patients’ lives after transsphenoidal resection.
