title: Ultrasonography and computed tomography of gastric wall lesions.
abstract: The ultrasonographic features of gastric wall lesions were studied in 40 patients and correlated with the CT findings in 14. Features diagnostic of tumor included (a) an infiltrative lesion causing thickening of the gastric wall, which can be localized or diffuse and smooth or irregular; (b) a globular mass, nodular or irregular, poorly or irregularly echogenic or containing a necrotic cavity; and (c) a combination of both, resulting in a rather complicated configuration. Gastritis and gastric ulcers also cause thickening of the gastric wall, but to a lesser extent.
