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.

Postbulbar stenosis.In this patient with gastrojejunostomy, postbulbar ulcer stenosis is shown on magnetic resonance cholangiopancreatography image. In addition, major papilla appears to be retracted cranially to bulbus, producing hook-shaped configuration. Intra- and extrahepatic biliary ducts appear mildly dilated. B = duodenal bulbus

Figure 13: Postbulbar stenosis.In this patient with gastrojejunostomy, postbulbar ulcer stenosis is shown on magnetic resonance cholangiopancreatography image. In addition, major papilla appears to be retracted cranially to bulbus, producing hook-shaped configuration. Intra- and extrahepatic biliary ducts appear mildly dilated. B = duodenal bulbus

Mentions: Peptic ulcer disease is the most common cause of benign duodenal stenosis. Duodenal ulcer may cause ectopic drainage of the CBD producing a hook-shaped configuration at its distal end (3132). In addition, benign conditions such as duodenal Crohn's disease and chronic pancreatitis, non-steroidal anti-inflammatory drugs, trauma, hyperplasia of Brunner's gland, corrosive agents, and malignant pathologies (duodenum, pancreas, gallbladder, ampulla) or metastases can cause duodenal stenosis or obstruction (Fig. 13) (31).
