Abstract
We report here a rare case of a gastric inflammatory fibroid polyp, which caused ball valve syndrome. An 85-year-old man who was followed up for a gastric submucosal tumor at our outpatient clinic was admitted to our hospital due to epigastric pain and vomiting. An emergency endoscopy, upper gastrointestinal series and abdominal computed tomography showed that the gastric submucosal tumor had prolapsed into the duodenum, and the symptoms were considered to have been induced by ball valve syndrome. Local surgical resection of the stomach was chosen to treat the ball valve syndrome. A surgical specimen revealed an inflammatory fibroid polyp in the stomach.
