“…Чувствительность КТ в диагностике аденом составляет 50% [34], однако она возрастает до 67% при адекватном расширении просвета кишки [35], что является одним из ключевых аспектов в диагностике аденом ДПК при КТ. При КТ и МРТ с контрастным усилением аденома -округлое, хорошо отграниченное образование с листовидными контурами (frond-like), умеренно накапливающее КП, без признаков инвазии и отдаленного метастазирования [3,34,36]. Аденомы пролабируют в просвет кишки и практически не бывают причиной обструкции [37].…”

Aim: To present the computed tomography and magnetic resonance imaging assessments of benign and malignant duodenal tumors, pancreatic head adenocarcinoma invading the duodenum, and duodenal dystrophy.Methods: We searched for scientific papers and clinical guidelines in the information and analytical databases PubMed and Google Scholar from the 2013–2021 period using the following search terms: duodenal neoplasms, adenocarcinoma, duodenum, duodenal neuroendocrine tumors, duodenal adenoma, gastrointestinal stromal tumor, cholangiocarcinoma, radiology, magnetic resonance imaging, computed tomography, pancreatic head cancer. Then, we examined the reference lists of all the identified studies to collate the papers that would meet the eligibility criteria.Results: We analyzed 1494 articles, 22 of which were included in our review. From the papers published within 1992–2021, 35 articles from the reference lists were additionally included. Based on the search results, several domains of articles were clustered; the articles from those domains were reviewed and evaluated that involved the abovementioned diagnostic features.Conclusion: The early diagnosis and selection of appropriate management methods remain extremely relevant for the treatment of duodenal tumors, and hence, require careful attention from diagnosticians and clinicians.

ObjectivesTo evaluate the magnetic resonance imaging (MRI) features of bile duct adenoma.MethodsThe data of 28 patients [with 32 pathologically confirmed bile duct adenomas, including 15 with malignant change (malignant group) and 17 without malignant change (benign adenoma group)] were retrospectively reviewed. Abdominal MRI was performed for all patients; in addition, dynamic enhanced MRI was performed for 18 lesions. The MRI features, including lesion location, maximum size, morphology, signal characteristics, enhancement type, and appearance of the bile duct, were assessed by two abdominal radiologists. Apparent diffusion coefficient (ADC) values were measured and compared.ResultsOf the 32 bile duct adenomas, 22 (68.75%) involved the common bile duct (CBD). While 14/32 (43.75%) lesions presented as focal eccentric-type masses, 9/32 (28.13%) presented as plaque-like masses, 4/32 (12.50%) as bile duct casting masses, and 5/32 (15.62%) as infiltrative masses. A frond-like superficial appearance was seen in 8/32 (25%) lesions. Infiltrative masses were significantly more common in the malignant group than in the benign adenoma group (P = 0.015). While 23/32 (71.88%) lesions were isointense on T1-weighted imaging (T1WI), 24/32 (75%) were hyperintense on T2-weighted imaging (T2WI). Bile duct dilatation was present upstream of the lesion in all cases. Bile duct dilatation at the lesion was seen in 24/32 (75%) cases and downstream of the lesion in 6/32 (18.75%) cases. Of the 18 lesions that underwent dynamic enhanced MRI, 14 (77.78%) showed moderate enhancement and 13 (72.22%) showed persistent enhancement. On diffusion-weighted imaging (DWI), 27/32 (84.37%) lesions showed hyperintensity. Mean ADC value was comparable between the malignant group and the benign adenoma group (P = 0.156).ConclusionsBile duct adenoma primarily presents as intraductal growth in the CBD, usually with bile duct dilatation at the lesion site or upstream to it. Most lesions are isointense on T1WI, are hyperintense on T2WI and DWI, and show moderate enhancement. A superficial frond-like appearance of the lesion and bile duct dilatation at the lesion or downstream to it might be characteristics of bile duct adenoma. An infiltrative appearance might indicate malignant transformation.
