Abstract

|
Gastric adenomyoma is a rare benign subepithelial tumor, characteristically composed of mucosal structures and a prominent smooth muscle stroma. Because of rarity and the nonspecific computed tomography (CT) features, it is difficult to diagnose gastric adenomyoma before operation. In our case, gastric adenomyoma showed a well-circumscribed cystic subepithelial mass with uneven wall thickness on a CT scan, similar to the findings of former reports. The radiologic differential diagnosis can be narrowed down to several diseases, including duplication cysts, gastritis cystica profunda, brunner's gland hyperplasia and solid tumors with cystic degeneration. Also, adenomyoma could be included in the differential diagnosis of gastric cystic subepithelial masses, especially in the distal part of the stomach.
