Sonography of polypoid gastric lesions by the fluid-filled stomach method

The fluid-filled stomach allows visualization of the gastric wall on real-time ultrasonic examination. In four cases with small focal gastric wall lesions (two cases with hyperplastic polyps, one with pseudopolypoid lesions, and one with polypoid infiltration of the gastric mucosa by malignant lymphoma), typical ultrasonic pictures were demonstrated. The polypoid lesions were located on the anterior and posterior gastric walls and at the gastric fundus, respectively. All who use the gastric sonic window for imaging the pancreas or the left upper abdomen should be aware that focal gastric lesions are also observable.
