Анализ биопсийного материала, полученного в ходе цистоскопии, выявил высокодифференцированную муцинозную аденокарциному урахуса. На основании установленного диагноза злокачественного новообразования первичного мочевого протока (урахуса) pT3N0M0 II ст. больной было показано хирургическое лечение. В июне 2023 г. проведена операция в объеме лапароскопической передней экзентерации таза с формированием кишечного резервуара по Bricker. При контрольном обследовании через 3 мес прогрессирования заболевания не выявлено. Асимптомность развития рака урахуса на ранних стадиях, особенности его расположения в полости малого таза и склонность к метастазированию, равно как и редкость самого новообразования, указывают на необходимость более ранней и точной верификации диагноза. Данный клинический случай демонстрирует характерные клинические и лучевые признаки аденокарциномы урахуса, которые могут помочь рентгенологам, онкологам и урологам в постановке диагноза и выборе правильной тактики лечения.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the clinical observation of a patient born in 1965, who was examined and treated at the Russian Scientific Center of Roentgenoradiology for tumor of anterior bladder wall detected in May 2023 according to the results of radiation diagnostic methods (ultrasound, computed tomography, magnetic resonance imaging). Analysis of biopsy material obtained during cystoscopy revealed a highly differentiated mucinous urachal adenocarcinoma. Based on the diagnosis of malignant neoplasm of primary urinary tract (urachus) pT3N0M0 stage II, the surgical treatment was proposed. In June 2023, the Bricker procedure was performed: laparoscopic anterior pelvic exenteration with formation of intestinal reservoir. Control examination 3 months after showed no progression of the disease. Asymptomatic development of urachal carcinoma in early stages, peculiarities of its location in pelvic cavity and propensity to metastasis, as well as the rarity of such neoplasm indicate the need for earlier and more accurate verification of the diagnosis. This clinical case demonstrates characteristic clinical and imaging features of urachal adenocarcinoma, which may help radiologists, oncologists, and urologists in making diagnosis and choosing correct treatment tactics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>урахус</kwd><kwd>рак урахуса</kwd><kwd>карцинома урахуса</kwd><kwd>аденокарцинома урахуса</kwd><kwd>лучевая диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>urachus</kwd><kwd>urachal cancer</kwd><kwd>urachal carcinoma</kwd><kwd>urachal adenocarcinoma</kwd><kwd>radiation diagnosis</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">Buddha S, Menias C.O, Katabathina VS.
