case_images: A computed tomography was followed, which showed exactly the same findings of ultrasonography (Fig. 1).

case_images: According to the small bowel series along with the previous radiologic findings, a lymphoma or gastrointestinal stromal tumor having marked aneurysmal dilatations was suspected (Fig. 2).
case_images: There is markedly dilated lumen in the mass in connection with the lumen of afferent loop (arrowhead) and efferent loop with normal ileal mucosa (arrow).

case_images: By dividing the mass longitudinally, we could see a necrotic tumor with nodules on the serosal surface of the diseased ileum having normal looking proximal and distal small intestinal loops attatched to it (Fig. 3).
