MRI Findings of Intrinsic and Extrinsic Duodenal Abnormalities and Variations.

Dusunceli Atman E, Erden A, Ustuner E, Uzun C, Bektas M - Korean J Radiol (2015)

Bottom Line: This pictorial review aims to illustrate the magnetic resonance imaging (MRI) findings and presentation patterns of anatomical variations and various benign and malignant pathologies of the duodenum, including sphincter contraction, major papilla variation, prominent papilla, diverticulum, annular pancreas, duplication cysts, choledochocele, duodenal wall thickening secondary to acute pancreatitis, postbulbar stenosis, celiac disease, fistula, choledochoduodenostomy, external compression, polyps, Peutz-Jeghers syndrome, ampullary carcinoma and adenocarcinoma.MRI is a useful imaging tool for demonstrating duodenal pathology and its anatomic relationships with adjacent organs, which is critical for establishing correct diagnosis and planning appropriate treatment, especially for surgery.

Choledochoduodenal fistula.In this patient with jaundice, fistula tract between choledochus and duodenum (white arrow) is depicted on barium studies (A) and magnetic resonance cholangiopancreatography (MRCP) image (B). In barium study, filling of bile ducts with contrast medium through fistula is apparent (black arrows in A). Spontaneous bilioenteric fistulas most commonly occur secondary to gallstones and less often from peptic ulcer, malignancy and trauma. Barium studies are more informative and demonstrate fistula itself or reflux of contrast material into biliary system. MRI is valuable for depicting direct communication between biliary system and duodenum by means of MRCP, and it is also superior to other techniques in demonstrating primary pathology or underlying causes.

Mentions: Biliary tract fistulas are rare and may occur spontaneously or postoperatively. A long-term history of biliary stones, recurrent biliary tract infections, CBD stones, malignancy and previous biliary surgery are the most common causes of a choledochoduodenal fistula. In this situation, the biliary system is exposed to intestinal flora and fluid (33). It is reported that gallbladder cancer may develop secondary to the chemical irritation of this back flow via choledochoduodenal fistula (34). On plain films, air can be seen in the biliary tree (Fig. 15).
