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.

Choledochocele.On coronal T2-weighted (A) and magnetic resonance cholangiopancreatography (B) images, cystic dilatation of distal end of choledochus is noted at level of major papilla (arrow). Cystic dilatation of intraduodenal segment of choledochus is called choledochocele, which is consistent with type-III choledochal cysts according to Todani classification.

Figure 10: Choledochocele.On coronal T2-weighted (A) and magnetic resonance cholangiopancreatography (B) images, cystic dilatation of distal end of choledochus is noted at level of major papilla (arrow). Cystic dilatation of intraduodenal segment of choledochus is called choledochocele, which is consistent with type-III choledochal cysts according to Todani classification.

Mentions: Choledochocele, which is the cystic dilatation of the intraduodenal segment of the choledochus, is concordant with type-III choledochal cysts according to Todani classification. It constitutes 4% of all choledochal cysts (Fig. 10) (23). Choledochocele is often encountered in elderly males. It generally presents with acute pancreatitis. Moreover, gallstones, cholangitis, cholecystitis are also seen. As choledochoceles protrude into the duodenum lumen, they may cause duodenal obstruction symptoms, hemorrhage and perforation. There exists a risk of pancreatic divisum and malignity, although the risk is low (232425).
