Acute inflammation occurring in gastric aberrant pancreas followed up by endoscopic ultrasonography

Figure 1 Esophagogastroduodenoscopic and endoscopic ultrasonographic images of submucosal lesion at the first examination. A: Esophagogastroduodenoscopy. Submucosal lesion was visible in the antrum of the stomach; B: Endoscopic ultrasonography. Lesion (arrow heads) located in the third layer (submucosa) with a diameter of 20 mm, slightly hypoechoic internal echo, and anechoic lumen, regarded as the duct.

Figure 2 Esophagogastroduodenoscopy after inflammation. Esophagogastroduodenoscopy (EGD) revealed a more swollen submucosal lesion compared with the previous EGD.

Figure 3 Endoscopic ultrasonographic image after inflammation. On endoscopic ultrasonography (EUS), the lesion was more swollen, with a diameter of 35 mm. The internal echo-pattern was more hypoechoic than in the previous EUS (arrow heads).

Figure 4 Pathological findings of submucosal lesion. Pathologic examination showed ductal epithelial cells and acinar cells.
