Kwak, Bae, Park, Lee, Jeon, Cho, Kang, Ryu, and Lee: Gastritis Cystica Polyposa with Gastroduodenal Intussuception: A Case Report

Abstract

Gastritis cystica polyposa is an uncommon benign lesion that normally occurs on the gastric side of a gastroenterostomy site but is rarely found in patients without a prior history of stomach surgery. We report a case of a 41-year-old woman with gastrodeuodenal intussusception due to gastritis cystica polyposa that developed in an unoperated stomach. CT revealed gastroduodenal intussusception and a cystic and solid mass with fat density in the second portion of the duodenum. Surgery and a pathologic examination confirmed gastritis cystica polyposa.

A 41-year-old woman with gastritis cystica polyposa.

A. Axial image of contrast enhanced abdomen CT shows gastroduodenal intussuception (arrow).
B. Heterogeneous enhancing mass (arrow) is in the second portion of duodenum. Note the non-enhancing low attenuation portion (arrowhead) located in the distal portion of intussusception suggesting omental fat and cystic components.
C. Endoscopic view of the stomach shows that the distal portion of gastric antrum is intussuscepted through pyloric canal.
D. Post-reduction view shows a lobulated, polypoid mass, which is fixed at the lesser curvature side of the stomach by a stalk.
E. Gross photography shows a polypoid mass with submucosal stroma and herniated yellowish omental fat.
F. Microscopically, polypoid mass is composed of variable-sized cysts located in submucosa and mucosa (H & E staining, ×40).
