Primary adenocarcinoma from a gastric heterotopic pancreas: A case report

Figure 4 Endosonographic features of an abdominal solid cystic mass in a 58-year-old woman. A: A multilobulated solid cystic mass (7.0 cm × 4.8 cm) was identified; B: The mass extended to the duodenal bulb-descending junction, causing luminal stenosis. The duodenal wall showed tumor infiltration (irregular hypoechoic thickening of up to 1 cm). The cyst wall exhibited hypoechoic unevenness, suggesting mural involvement; C: The lesion had ill-defined borders with the fourth layer of the gastric wall (as indicated by green arrow).
