Abstract:
Objective To evaluate the role of CT in the diagnosis of the primary carcinoma of the duodenum.Methods CT findings of 15 patients with primary carcinoma of the duodenum(12 adenocarcinoma,3 carcinoid)underwent surgical treatment or biopsy were reviewed.Results 9/12 of adenocarcinomas were shown as local soft tissues masses;6/12 of adenocarcinomas manifested as ductal wall irregular or circular thickening;3/12 of adenocarcinomas were shown as local soft tissues masses accompanied with deformation and constriction of duodenum.Cholangiectasis,metastasis of retroperitoneal lymph nodes and liver were also founded.CT cannot difference adenocarcinoma with carcinoid.After enhancement,the masses were manifested as mild or intermediate enhancement in the early stage and they did not show obviously enhancement in the delay or portal stage.Conclusion CT play an important role in both the localization and qualitative diagnosis of the primary carcinoma of duodenum,but it is difficult to difference adenocarcinoma with carcinoid.
