case_images: A contrast-enhanced computed tomography (CECT) of the abdomen revealed dilated stomach with a hypodense lesion posteromedial to the second part of the duodenum (Fig. 1; arrow). Careful examination revealed an extrinsic bulge at the area of the narrowing (Fig. 1) and scope was negotiable across this narrowing.

case_images: Subsequently, endoscopic ultrasound (EUS) was performed with a radial echoendoscope and it revealed a 1.2 cm cystic lesion (Fig. 2) in the second part of the duodenum, at the site of narrowing. Careful examination revealed that muscularis propria of the duodenal wall was seen intact around this lesion (Fig. 2; arrow), suggesting an intramural location.
