| Abstract: | Gray scale ultrasound examination of two patients with abdominal space-occupying lesions demonstrated characteristic ring shadows on longitudinal scans. In one case a multiple concentric ring shadow resulted from an ileocolic intussusception, and in the other a  bull's eye image was due to an infiltrating carcinoma of the pyloric antrum.A study of these patients confirms the suspicion [1] that there is a characteristic ultrasonic appearance of intussusception in bowel loops. |
