Endosonographic Features of Histologically Proven Gastric Ectopic Pancreas

Figure 2

Ectopic pancreas originates from the second and third sonographic layers of the gastric wall. (a) A subepithelial tumor with intact but uneven surface was identified in the antrum. (b) Endoscopic ultrasonographic image obtained with a 12 MHz catheter probe. The tumor exhibits heterogeneous, mixed echoic echogenicity and indistinct margins, involving the second and third sonographic layers of the gastric wall (arrow).
