A case of thyrotropin (TSH)-secreting tumor complicated by periodic paralysis.

چکیده
A 27-year-old man had symptoms of hyperthyroidism and periodic paralysis. While hyperthyroid, his serum thyrotropin (TSH) level was inappropriately elevated at 6.4 microU/ml. The serum alpha subunit level was also elevated. MR imaging revealed a pituitary tumor and transsphenoidal adenomectomy was performed. Immunocytochemistry with an antibody directed against the beta-subunit of TSH revealed a TSH-secreting tumor. This is the first case of hyperthyroidism due to a TSH-secreting pituitary tumor complicated by periodic paralysis. This association indicates that thyrotoxicosis may induce paralysis in susceptible persons by a mechanism which is not autoimmune.

Thyrotoxic Periodic Paralysis (TPP) is a rare manifestation of hyperthyroidism characterized by muscle weakness and hypokalemia. Thyroid-Stimulating Hormone (TSH)-secreting pituitary adenoma is a rare cause of hyperthyroidism. Even more rare is the occurrence of TPP as the first manifestation of a TSH-secreting pituitary adenoma. We report a 31-year-old Asian male patient suffering from TPP cau...

متن کاملA Case of Thyrotropin-Secreting Pituitary Adenoma (TSH-oma)
Thyrotropin-secreting pituitary adenomas (TSHomas) are rare tumors and represent about 1-2% of all pituitary adenomas (prevalence is about one case per million) and cause secondary or central hyperthyroidism. The number of reported cases of TSH-omas tripled in the last decade. The increased number of reported cases resulted principally from the introduction of ultrasensitive immunometric assay ...
