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.

Duodenal wall thickening secondary to acute pancreatitis.In patient with acute pancreatitis, on axial (A) and coronal (B) fat-suppressed T2-weighted MR images, mural thickening and edema in second portion of duodenum are depicted (white arrow in A, black arrow in B). Pancreatitis is most common inflammatory process that affects duodenum. Inflammation of pancreas and release of exocrine enzymes may lead to mild to severe duodenal edema and gastric outlet obstruction. Moreover, in severe pancreatitis, intramural hematoma may also develop.

Figure 12: Duodenal wall thickening secondary to acute pancreatitis.In patient with acute pancreatitis, on axial (A) and coronal (B) fat-suppressed T2-weighted MR images, mural thickening and edema in second portion of duodenum are depicted (white arrow in A, black arrow in B). Pancreatitis is most common inflammatory process that affects duodenum. Inflammation of pancreas and release of exocrine enzymes may lead to mild to severe duodenal edema and gastric outlet obstruction. Moreover, in severe pancreatitis, intramural hematoma may also develop.

Mentions: Because the duodenum shows anatomic continuity with the pancreas, it is affected by the pathologies of the pancreas. Pancreatitis is the most frequently seen inflammatory process that affects the duodenum (710). Acute inflammation of the pancreas and excretion of exocrine enzymes may cause mild-severe duodenal edema, duodenal wall thickening and gastric outlet obstruction (Fig. 12) (710).
