Purpose: The aim of this study was to evaluate thyroid volume in women with prolactinoma and investigate the relationship between anabolic hormones [insulin, insulin like growth factor (IGF-1), estrogen] and thyroid volume in the patients. Material-method: Sixty-three euthyroid women with prolactinoma and 60 healthy euthyroid women were included. Serum prolactin (PRL), thyroid-stimulating hormone (TSH), thyroxine (free T4), free tri-iodothyronine (free T3), insulin resistance (IR) which was estimated by the homeostasis model assessment, thyroidal microsome (anti-TPO), antithyroglobulin antibodies (TgAb), estradiol (E2), and insulin like growth factor (IGF-1) were evaluated, and thyroid volume was calculated by B-mode doppler USG. Results: The mean thyroid volume was significantly higher in women with prolactinoma (82.5 ± 15.1 mL) than in healthy women (76 ± 15.1 mL)(P = 0.014), but no correlation was found between thyroid volume and serum PRL levels (P = 0.967). There were also no differences between thyroid volume, anabolic hormones (E2, IGF-1), and insulin resistance in women with prolactinoma (P = 0.776, P = 0.786, P = 0.647, respectively). Conclusions: Our study did not show an association between anabolic hormones and increased thyroid volume in women with prolactinoma. © 2015 Elsevier Masson SAS.
