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.

Prominent papilla.On coronal fast imaging employing steady-state acquisition MR image, nodular structure (arrow) is detected at level of major papilla (hypertrophic papilla). Normally, papilla is scarcely distinguished from surrounding duodenal mucosal folds, but as seen in this image, normal papillas may be seen as oval protruding structures of 5-10 mm. MRI and magnetic resonance cholangiopancreatography are important in hypertrophic papilla diagnosis and in detecting underlying pathology.

Figure 3: Prominent papilla.On coronal fast imaging employing steady-state acquisition MR image, nodular structure (arrow) is detected at level of major papilla (hypertrophic papilla). Normally, papilla is scarcely distinguished from surrounding duodenal mucosal folds, but as seen in this image, normal papillas may be seen as oval protruding structures of 5-10 mm. MRI and magnetic resonance cholangiopancreatography are important in hypertrophic papilla diagnosis and in detecting underlying pathology.

Mentions: The major duodenal papilla is the oval protrusion in the medial part of the descending segment of the duodenum. Although the papilla has a variable diameter, it is generally approximately 5-10 mm. The normal bulging of the papilla into the duodenum lumen is smaller than 1 cm (3). Normally, the papilla is scarcely differentiated from the duodenal mucosal folds around it (45). Although hypertrophic papilla can rarely occur as a normal variant, it may also develop in connection with inflammatory (acute cholangitis, acute pancreatitis, biliary calculus, periampullary diverticulum, infection-infestation, etc.) or neoplastic processes (intraductal papillary mucinous tumor, ampullary adenoma and tumor, periampullary cancer, etc.) (Fig. 3) (45).
