A Case of Follicle-stimulating Hormone-secreting Pituitary Adenoma Accompanied by Painful Thyroiditis.

A Case of Follicle-stimulating Hormone-secreting Pituitary Adenoma Accompanied by Painful Thyroiditis. Intern Med. 2019 Oct 15;: Authors: Ichijo M, Tsuchiya K, Kasai T, Inoshita N, Yoshimoto H, Yamada S, Kitamura K Abstract A 30-year-old woman with multiple ovarian cysts presented with high serum estradiol levels. She had a pituitary adenoma, but the follicle-stimulating hormone (FSH) concentration was within the normal range. The patient complained of neck pain and palpitations during the disease course, and laboratory results revealed thyrotoxicosis and a systemic inflammatory response with negative findings for anti-thyroid stimulating hormone (TSH) receptor antibody and positive findings for anti-thyroglobulin and anti-thyroid peroxidase antibodies. Prednisolone improved the symptoms and the thyroid function and was discontinued after two months. A histological examination of the pituitary tumor confirmed it to be FSH-producing pituitary adenoma, with subsequent normalization of the serum estradiol concentration.
