Проведен ретроспективный анализ компьютерных томограмм 36 больных с аденокарциномой головки поджелудочной железы и 24 больных с хроническим панкреатитом с преимущественным поражением головки поджелудочной железы, осложненных билиарной и/или дуоденальной обструкцией. Панкреатодуоденальная резекция выполнена 14 больным с раком железы и 9 — с хроническим панкреатитом. Декомпрессивные вмешательства выполнены 35 больным обеих групп.Результаты. При раке образование в нативную фазу в 97 % изоденсное, в артериальную фазу в 94 % становится гиподенсным, при хроническом панкреатите — 67 и 46 % соответственно. Кривая показателей плотности во всех фазах практически одинакова, но разница в градиенте плотности больше при раке (27 HU против 15 HU). При раке чаще определяется стриктура холедоха по типу «обрыва» (44 %) и инвазия артериальных сосудов (25 %). При хроническом панкреатите чаще определяются вирсунголитиаз (21 %), портальная гипертензия (42 %). Практически одинаково представлены такие признаки, как полостные образования, инфильтрация парапанкреатической клетчатки и регионарная лимфоаденопатия. В 6 случаях рака головки и 7 хронического панкреатита были выявлены одинаковые патологические изменения при интраоперационной ревизии: кистозные образования (2 и 4), участки инфицированного некроза и абсцессы в железе и клетчатке (3 и 2) и идентичная картина на cрезе макропрепарата (1 и 1).Заключение. Объективной причиной затруднения дифференциальной диагностики рака и хронического панкреатита с преимущественным поражением головки поджелудочной железы является перекрест КТ-признаков, обусловленный схожими патоморфологическими изменениями.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To identify the underlying causes of complications in distinguishing the origin of head masses through a comparative analysis of CT findings and clinical observations.Materials and methods. A retrospective analysis of radiological imaging for pancreatic cancer (36 cases) and chronic pancreatitis (24 cases) was conducted. Pancreaticoduodenectomy was performed in 23 cases (14 for cancer and 9 for chronic pancreatitis), while drainage interventions were carried out in 35 cases.Results. On pre-contrast images, pancreatic cancer appeared isodense in 97 % of cases, while in the arterial phase, it was hypodense in 94 %. For chronic pancreatitis, these percentages were 67 % and 46 %, respectively. The density curves of the pancreatic head and normal parenchyma were nearly identical across all phases, but the density gradient difference was more pronounced in pancreatic cancer (27 HU compared to 15 HU). Bile duct strictures with interruption were observed more frequently in cancer (44 %), along with arterial vessel invasion (25 %). CT signs indicative of chronic pancreatitis included wirsugolithiasis (21 %) and portal hypertension (42 %). Both diseases exhibited similar CT features, such as cystic lesions, peripancreatic tissue infiltration and peripancreatic lymphadenopathy. In six cases of pancreatic head cancer and seven of chronic pancreatitis, identical pathological changes were identified during intraoperative revision: pseudocysts (2 in cancer and 4 in chronic pancreatitis), infected necrosis and abscesses (3 and 2, respectively) and similar views of the head mass cut plane (1 each).Conclusion. The overlap in CT features due to similar pathomorphological changes presents an objective challenge in differentiating pancreatic head masses</p></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерная томография</kwd><kwd>поджелудочная железа</kwd><kwd>рак</kwd><kwd>панкреатит</kwd><kwd>диагноз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computed tomography</kwd><kwd>pancreatic cancer</kwd><kwd>mass-forming pancreatitis</kwd><kwd>diagnostics</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">Dutta AK, Chacko A.
