A diffuse thickening of the gastric wall (between the arrows), without a discretely marginated mass or ulceration can be seen on OCEUS (a) and it enhanced with a layered pattern (arrows in a) during the arterial phase using CEUS (b); poorly differentiated adenocarcinoma was confirmed on histopathological examination with H&E staining (x100) (c).
