Abstract
A 62-year-old man presented with upper abdominal discomfort underwent upper gastrointestinal endoscopy. Gastroscopy and endoscopic ultrasonography revealed a submucosal tumor (SMT) with homogenous echogenicity originated from extragastric organs. An abdominal contrast-enhanced computed tomography (CT) showed that the well-marginated ovoid mass, approximately 6 cm in diameter, enhanced homogenously to a similar degree as splenic parenchyma. 99mTechnetium sulfur colloid scintigraphy revealed the splenic nature of the mass. A diagnosis of accessory spleen mimicking gastric SMT was made. Subsequent follow-up was uneventful without performing splenectomy.
