A gastric bezoar causing a target lesion as revealed by ultrasound.

Abstract
A case of a bezoar of the stomach causing a "target lesion" of the gastrointestinal tract is presented. The observance of this mass as water passed through the stomach may, in the future, differentiate the mass from a true stomach-wall lesion as more of these patterns are recognized. Other lesions that may enter into the differential diagnosis are blood clots and pedunculated polyps.
