Splenic Cyst Mimicking Gastric Subepithelial Tumor Diagnosed by Endoscopic Ultrasonography

Recent research reveal that the diagnosis of gastric extraluminal compressions mimicking subepithelial tumor is increasing in numbers as esophagogastroduodenoscopy becomes widespread. Endoscopic ultrasonography is a very useful tool for differentiating extraluminal compressions from subepithelial tumors. Gastric extraluminal compressions are due to compression by either normal adjacent organs or pathologic conditions. Pathologic conditions are mainly benign, but some requires operation according to its size. We report a case of a 24-year-old female, who underwent esophagogastroduodenoscopy and was misdiagnosed with gastric subepithelial tumor. Endoscopic ultrasonographic findings showed anechoic cyst outside the gastric wall, which revealed to be a splenic cyst. (Korean J Helicobacter Up Gastrointest Res 2012;12:116-119)
