Проведено клиническое исследование 75 больных с гистологически подтвержденным диагнозом аденомы гипофиза. Средний возраст 51,3±14,8 лет, медиана составила 52 (37/65) года. Предоперационно постановка диагноза основывалась на клинико-лабораторных данных, результатах нейровизуализационных методов исследования. В исследовании осуществлен анализ нейровизуализационных предикторов консистенции аденомы в дооперационном периоде, с последующим подтверждением интраоперационно. Интраоперационная интерпретация плотности опухоли основывалась на классификации M. J. Rutkowski (2020).</p></sec><sec><title>Результаты</title><p>Результаты. Для всех исследуемых пациентов был применен транссфеноидальный доступ с эндоскопической ассистенцией. Радикальное удаление выполнено в 89,3 % случаев (N=67), субтотальное удаление – у 10,7 % (N= 8). У всех субтотально оперированных пациентов через 3–6 месяцев при контроле МРТ наблюдался продолженный рост опухоли, что у ряда пациентов потребовало в дальнейшем выполнения повторного транссфеноидального удаления процедива (у 9,4 %), а в 1,3 % – транскраниального удаления (через латеральный супраорбитальный доступ). Корреляции с гистологическими подтипами опухоли и уровнем Ki-67 не отмечено. При анализе интраоперационно преимущественно встречалась мягкая консистенция аденомы гипофиза (74,7 %), средняя и плотная консистенция – реже (10,7 и 13,3 % соответственно). Т1-изотенсивный сигнал может являться предиктором интраоперационно более мягкой плотности аденомы гипофиза (r=0,383; p=0,02). Гиперинтенсивность Т2-сигнала только в сочетании с повышенными значениями маркеров гипокоагуляции (ПТВ и МНО) может свидетельствовать о мягкой плотности аденомы гипофиза (p&lt;0,04).</p></sec><sec><title>Выводы</title><p>Выводы. Прогнозирование консистенции опухоли на предоперационном этапе является важным фактором в планировании хирургической тактики, но не единственным. Прогноз плотной структуры опухоли в сочетании с оценкой ее инвазивности – латероселлярного роста в кавернозный синус (Knosp 3–4), супраселлярным распространением в структуры гипоталамуса, желудочковую систему (Hardy 3–4), могут предоперационно свидетельствовать о высокой вероятности продолженного роста, целесообразности транскраниального удаления опухоли, сроках контрольных дообследований, необходимости радиохирургического лечения.</p></sec></abstract><trans-abstract xml:lang="en"><p>The objective was to identify preoperative neuroimaging parameters that predict the consistency of pituitary adenoma intraoperatively and determine further treatment tactics.</p><sec><title>Material and methods</title><p>Material and methods. A clinical study of 75 patients with a histologically confirmed diagnosis of pituitary adenoma was conducted. The average age was 51.3±14.8 years, the median was 52 (37/65) years. Preoperative diagnosis was based on clinical and laboratory data, the results of neuroimaging research methods. The study analyzed neuroimaging predictors of adenoma consistency in the preoperative period, with subsequent confirmation intraoperatively. Intraoperative interpretation of tumor density was based on the classification of Rutkowski M.J. (2020).</p></sec><sec><title>Results</title><p>Results. Transsphenoidal access with endoscopic assistance was used for all the studied patients. Radical removal was performed in 89.3 % of cases (N=67), subtotal removal in 10.7 % (N= 8). In all subtotally operated patients, after 3–6 months, continued tumor growth was observed in MRI monitoring, which in a number of patients required repeated transsphenoidal removal of the sac (in 9.4 %), and in 1.3 % – transcranial removal (through lateral supraorbital access). There was no correlation with histological subtypes of the tumor and the level of ki-67. During the intraoperative analysis, the soft consistency of pituitary adenoma was predominantly found (74.7 %), medium and dense consistency was less common (10.7 and 13.3 %, respectively). T1-isotensive signal may be a predictor of intraoperatively milder pituitary adenoma density (r=0.383; p=0.02). Hyperintensivity of the T2 signal only in combination with elevated values of hypocoagulation markers (PTT and INR) may indicate a soft density of pituitary adenoma (p&lt;0.04).</p></sec><sec><title>Conclusions</title><p>Conclusions. Predicting tumor consistency at the preoperative stage is an important factor in planning surgical tactics, but not the only one. The prognosis of a dense tumor structure combined with an assessment of its invasiveness – laterosellar growth into the cavernous sinus (Knosp 3–4), suprasellar spread into the structures of the hypothalamus, ventricular system (Hardy 3–4), may preoperatively indicate a high probability of continued growth, the expediency of transcranial removal of the tumor, the timing of follow-up examinations, the need for radiosurgical treatment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аденомы гипофиза</kwd><kwd>консистенция аденомы</kwd><kwd>предоперационная оценка</kwd><kwd>МР-оценка</kwd><kwd>транссфеноидальная хирургия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pituitary adenomas</kwd><kwd>adenoma consistency</kwd><kwd>preoperative assessment</kwd><kwd>MR assessment</kwd><kwd>transsphenoidal surgery</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">Ostrom Q.
