title: Ultrasound demonstration of lesions of the gastrointestinal tract.
abstract: An ultrasonographic pattern of mass lesions with strong central echoes appears to be specific for lesions of the luminal GI tract. Three lesions from different portions of the GI tract showing this appearance are presented. Although ultrasound is not the technique of choice in the diagnosis of lesions of the luminal gastrointestinal tract, it is sometimes preferable to perform ultrasound prior to barium studies, and hence it is important to recognize this characteristic appearance.
