Abstrakt: A 51-year-old woman visited our hospital with the chief complaint of tarry stools. Contrast-enhanced abdominal computed tomography revealed leakage of contrast medium into the lumen of the small intestine. Subsequently, a double-balloon endoscopy was performed, which revealed a submucosal mass-like lesion in the jejunum. Although hemostasis was attempted with clips, complete hemostasis was difficult to achieve, and angiographic embolization was performed. Nevertheless, the anemia progressed, and a small bowel resection was performed. Histopathological examination led to a diagnosis of a ruptured submucosal aneurysm of the small intestine. Endoscopic hemostasis is often difficult to achieve for submucosal aneurysms in the intestine. The submucosal tumor-like finding observed on endoscopy in submucosal aneurysms is termed an "SMT-like sign" and is considered an important finding to diagnose aneurysms.
