A Case Report of Calcifide Gastric Leiomyoma Developed from the Upper Body in Accompany with Invagination into the Duodenal Bulbus

Abstract

Gastric leiomyoma is the most common submucosal tumor of the stomach. Recent progress in diangostic techniques allows better diagnosis of gastric leiomyoma, but it is very difficult to diagnose the tumor in the case of invagination into the duodenal bulbus. We encountered a rare case of calcified leiomyoma at the upper body of the stomach, invaginating into the duodenal bulbus. A 46-year-old woman was hospitalized with acute epigastralgia and vomiting, so called “ball valve syndrome” an upper gastrointestinal series and gastrofiberscopy revealed a submucosal tumor at the upper body of the stomach invaginating into the duodenal bulbus. Ultrasonography and computed tomography revealed a calcified spot in this tumor. Gastrectomy was performed. The histologic diagnosis was gastric leiomyoma.
