Объектами исследования являются кошки с гастроэнтерологическими нарушениями с подозрением на алиментарную лимфому разного возраста и пола. Диагноз ставился на основании клинического обследования по общепринятым методикам, лабораторного исследования крови, ультразвукового исследования, патоморфологического исследования стенок кишечника и лимфатических узлов, цитологического исследования материала лимфатических узлов, полученного методом ТИАБ (Тонкоигольная аспирационная биопсия). Авторы проводили забор материала для цитологического исследования методом черезкожной аспирационной тонкоигольной биопсии под ультразвуковым контролем на аппарате Mindray Z6 Vet. При анализе результатов ультразвукового исследования у кошек с диагнозом алиментарная лимфома в 12 % случаев наблюдалась гепатомегалия, 1 – асцит, 3 – гидроторакс, 3 – увеличение средостенных лимфоузлов, 7 – спленомегалия, 16 – нарушение дифференциации слоев кишечника, 16 – нарушение дифференциации слоев кишечника, 29 – увеличение мезентериальных лимфоузлов и 29 % – утолщение стенок кишечника. При цитологическом исследовании обнаружены округлые, крупные, отдельно расположенные клетки, популяция мономорфная. При гистологическом исследовании в стенке кишечника, прилегающей жировой ткани сальника и ткани лимфатического узла присутствует высококлеточное инвазивное образование, построенное из диффузных пластов округлых лимфоидных неопластических клеток со скудной фиброзной стромой. Наиболее характерными ультразвукововыми находками являются утолщение стенок кишечника, увеличение мезентериальных лимфоузлов.</p></abstract><trans-abstract xml:lang="en"><p>The study aimed to determine the characteristic changes in alimentary lymphoma in cats during ultrasonography, pathoanatomic and cytological examination of biopsy material. The survey objects are cats with gastroenterological disorders with suspected alimentary lymphoma of different ages and genders. The diagnosis was made based on a clinical examination according to generally accepted methods, laboratory blood examination, ultrasound examination, pathomorphological examination of the intestinal walls and lymph nodes, and cytological examination of the lymph node material obtained by the TIAB method. The authors carried out the material sampling for cytological examination using percutaneous fine needle aspiration (FNA) biopsy under ultrasound control on the Mindray Z6 Vet apparatus. In addition, the authors conducted pathological and cytological studies in the Vet Union laboratory. When analyzing ultrasound examination in cats diagnosed with alimentary lymphoma, hepatomegaly, 1% ascites, 3% hydrothorax, 3 % increase in mediastinal lymph nodes, 7% splenomegaly, 16% violation of differentiation of intestinal layers, 16% violation of differentiation of intestinal layers, 29% increase in mesenteric lymph nodes, 29 % thickening of intestinal walls were observed in 12% of cases. Cytological examination revealed rounded, large, separately located cells. The population is monomorphic. During a histological study in the intestinal wall, adjacent fatty tissue of the omentum, and lymph node tissue, there is a highly cellular invasive formation constructed from diffuse layers of rounded lymphoid neoplastic cells with a scanty fibrous stroma. The most characteristic ultrasound findings are the thickening of the intestinal walls and an increase in mesenteric lymph nodes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алиментарная лимфома</kwd><kwd>кошки</kwd><kwd>биопсия</kwd><kwd>мезентериальные лимфоузлы</kwd><kwd>стенка кишечника</kwd></kwd-group><kwd-group xml:lang="en"><kwd>alimentary lymphoma</kwd><kwd>cats</kwd><kwd>biopsy</kwd><kwd>mesenteric lymph nodes</kwd><kwd>intestinal wall</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">World Health Organisation Classification of Lymphoid Tumours in Veterinary and Human Medicine: a Comparative Evaluation of Gastrointestinal Lymphomas in 61 Cats / B.
