Независимо от разрешающей способности магнитно-резонансной томографии (МРТ) и применения контрастирования до 20% АКТГ-секретирующих аденом гипофиза выявляются только в ходе хирургического вмешательства. </p><p>Цель исследования — оценить связь количества и диаметра кровеносных сосудов в АКТГ-секретирующих аденомах гипофиза с возможностью их визуализации при МРТ.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проведена ретроспективная оценка образцов ткани АКТГ-секретирующих аденом гипофиза у 39 пациентов с болезнью Иценко—Кушинга; у 17 пациентов аденома не была обнаружена при МРТ, а у 22 больных размер аденомы был менее 25 мм. МРТ проводилась на аппарате Siemens Magnetom Harmony 1.0T с гадолиниевым контрастированием. Образцы опухолей исследовали иммуногистохимически с антителами к антигенам СD34 и D2-40; рассчитывали плотность микрососудов и диаметр наибольшего и наименьшего сосуда.</p></sec><sec><title>Результаты</title><p>Результаты. Плотность кровеносной сети в аденомах, выявленных и не выявленных при МРТ [123 (77; 136) и 112 (110,0; 126,5)] сосудов на единицу площади, соответственно), а также количество щелевидных сосудов [32 (5; 50) и 25 (5; 50)] на единицу площади, соответственно) статистически значимо не различались (p&gt;0,05). Не выявлено статистически значимых различий и в диаметре этих сосудов: диаметр наибольшего сосуда в невыявленных при МРТ аденомах — 53 мкм (32,5; 63,5), в выявленных — 33 мкм (30,0; 51,5), средний диаметр кровеносных сосудов — 15 мкм (14,5; 26,0) и 13 мкм (12; 14) соответственно.</p></sec><sec><title>Заключение</title><p>Заключение. Диаметр и количество кровеносных сосудов в аденомах у пациентов с Болезнью Иценко-Кушинга не влияют на возможность обнаружения опухоли с помощью МРТ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Regardless of improvements in MRI, up to 20% of ACTH-secreting pituitary tumors are only identified at surgical exploration. </p></sec><sec><title>Aim</title><p>Aim. Тo estimate whether there is any difference in blood vessels and the subsequent ability to uptake contrast agent in visualized microadenoma as compared to non-visualized on MRI ACTH-secreting pituitary tumors.</p></sec><sec><title>Material and methods</title><p>Material and methods. Retrospective evaluation of ACTH-positive pituitary tumors from patients with Cushing’s disease (n=39) with either non-visualized pituitary tumor on MRI (n=17) or pituitary tumor less then 25 mm (n=22). MRI was performed using Siemens Magnetom Harmony 1.0T with gadolinium. Selected tumors were stained with anty-СD34 antibody (clone QBEnd/10, RTU, Leica) and anty-D2-40 antibody (clone D2-40, RTU, Dako). We evaluated the microvessels density and measured the diameter of larger and smaller vessel.</p></sec><sec><title>Results</title><p>Results. The microvessels density were not different in subject with visualized [123 (77; 136)] and non-visualized [112 (110,0; 126,5)] pituitary adenomas as well as number of slit-shaped vessels [32 (5; 50) in visualized vs 25 (5; 50) in non-visualized pituitary adenoma]. The diameter of these vessels also did not differ: the diameter of the largest vessels in patients without visualization 53 µm (32,5; 63,5) vs 33 µm (30,0; 51,5) the average diameter of the blood vessels 15 µm (14,5—26,0) against 13 µm (12; 14).</p></sec><sec><title>Conclusions</title><p>Conclusions. The diameter and microvessels density in ACTH-producing pituitary adenoma does not affect the visualization of adenoma on MRI in patients with Cushing ‘s disease.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>АКТГ-зависимый гиперкортицизм</kwd><kwd>кортикотропинома</kwd><kwd>эндогенный гиперкортицизм</kwd><kwd>Болезнь Иценко-Кушинга</kwd><kwd>ангиогенез в аденомах гипофиза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ACTH-dependent hypercorticism</kwd><kwd>corticotropinoma</kwd><kwd>endogenous hypercortisolism</kwd><kwd>Cushing's disease</kwd><kwd>angiogenesis in pituitary adenomas</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Российский Научный Фонд №15-15-30032</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Мельниченко Г.А., Дедов И.И., Белая Ж.Е., и др.
