Неспецифичность симптомов и их проявление только в поздний период развития заболевания приводят к тому, что при первичной диагностике у пациентов выявляются III–IV стадии рака. Гастроинтестинальная стромальная опухоль (ГИСО) – подслизистая опухоль желудочно-кишечного тракта, являющаяся производной от интерстициальных клеток Кахаля. Уникальность представленного клинического случая в том, что ГИСО двенадцатиперстной кишки встречается крайне редко и оказалась случайной находкой при диагностике аденокарциномы поджелудочной железы. Диагностированный на компьютерной томографии с контрастированием синхронный рак (аденокарцинома головки поджелудочной железы и ГИСО двенадцатиперстной кишки) был подтвержден патогистологически после операции Уиппла. Продемонстрированы возможности диагностики синхронного рака при помощи компьютерной томографии с внутривенным контрастным усилением.</p></abstract><trans-abstract xml:lang="en"><p>Pancreatic adenocarcinoma is the most pervasive form of cancer with high mortality rates. Being obscure at the early stages, non-specific symptoms and their onset only in the late stages of the disease lead to detection of the III–IV stages cancer on initial diagnistics. Gastrointestinal stromal tumor (GIST) is an intramucosal tumor of gastrointestinal tract, which is a derivate of interstitial cells of Cajal. The unicity of the presented clinical case is the rareness of GIST, which was an incidental finding during diagnostics of pancreatic adenocarcinoma. Diagnosed by intravenous contrast computed tomography, synchronous pancreatic and duodenal double cancer was confirmed histologically after Whipple surgery. The opportunities of intravenous contrast computed tomography in diagnostics of synchronous cancer were demonstrated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аденокарцинома поджелудочной железы</kwd><kwd>гастроинтестинальная стромальная опухоль</kwd><kwd>компьютерная томография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pancreatic adenocarcinoma</kwd><kwd>gastrointestinal stromal tumor</kwd><kwd>computed tomography</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">Agaimy A, Wuensch PH.
