Ovarian hyperthecosis is the most common cause of hyperandrogenism in women during postmenopausal age. However, its diagnosis is frequently challenging, since several causes must be ruled out, involving both adrenal glands and ovaries. Herein we describe the case of a 62 years old woman addressed to our Unit after the casual detection of an adrenal mass, compatible with an adenoma. Biochemical evaluation revealed gonadotropins in menopausal range, high testosterone and androstenedione, while the patient had been complaining of androgenetic alopecia and hirsutism for some years. Ultrasound imaging revealed only a small increase in ovarian volume, in relationship to the patient’s age. A GnRHa test was performed, demonstrating gonadotropins suppression and testosterone normalization, thus confirming the suspect of ovarian hyperthecosis. The administration of these agonists, together with the slow progression of symptoms over years, play a fundamental role into excluding an androgen-secreting neoplasia, also limiting the use of ovarian veins catheterization as second line test. Besides, they represent a valid therapeutical option, especially when surgery is contraindicated (or cannot be performed).
