В большинстве случаев гонадотропиномы являются «молчащими» и составляют более половины гормонально-неактивных аденом гипофиза. В статье представлено описание редкого клинического наблюдения: ЛГ/ФСГ-секретирующей макроаденомы гипофиза с развитием битемпоральной гемианопсии у 62-летнего мужчины. Пациенту была проведена трансназальная транссфеноидальная аденомэктомия, позволившая достичь ремиссии заболевания. Отличительной особенностью данного случая являлось наличие вторичного эритроцитоза, развившегося вследствие эндогенной гиперандрогении, что потребовало проведения процедур эксфузий крови с целью нормализации уровня гематокрита перед проведением оперативного вмешательства. Примечательно, что клинические признаки эритроцитоза у пациента были выявлены задолго до развития зрительных нарушений. Представленный клинический случай демонстрирует сложность ранней диагностики гормонально-активных гонадотропином.</p></abstract><trans-abstract xml:lang="en"><p>Functioning gonadotroph adenomas are rare pituitary tumors secreting one or two gonadotropins (follicle-stimulating hormone (FSH) and/or luteinizing hormone (LH)), which are hormonally active. In the majority of cases, gonadotroph tumors are endocrinologically “silent” and make up more than a half of non-functioning pituitary adenomas. In this article we describe a rare clinical case of LH/FSH-secreting pituitary macroadenoma with bitemporal hemianopsia in a 62-year-old man. The patient underwent transnasal transsphenoidal adenomectomy, leading to remission. The distinctive feature of this case is the presence of secondary erythrocytosis due to endogenous hyperandrogenism, which required several blood exfusions to normaliza the level of hematocrit before surgery. It is noteworthy that clinical signs of erythrocytosis were present long before visual impairment. This clinical case demonstrates difficulties in the early diagnosis of functioning gonadotroph adenomas.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аденома гипофиза</kwd><kwd>гонадотропинома</kwd><kwd>ЛГ</kwd><kwd>ФСГ</kwd><kwd>гиперандрогения</kwd><kwd>эритроцитоз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pituitary adenoma</kwd><kwd>gonadotroph tumor</kwd><kwd>LH</kwd><kwd>FSH</kwd><kwd>hyperndrogenism</kwd><kwd>erythrocytosis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ntali G, Capatina C, Grossman A, Karavitaki N.
