Ultrasonographic features of gastrointestinal duplications

Ultrasonography can easily detect multiple unsuspected cysts and complications such as perforation. Serial sonograms demonstrated the changing morphology of two cysts. Other unsuspected intra-abdominal and pelvic pathologic conditions, including pyloric stenosis and ovarian cysts were identified. Identification of the mascular rim sign is the most reliable indication of a duplication cyst. Multiple masses as well as possible accompanying anomalies in the abdomen and pelvis are readily evaluated with sonography. Lesions are easily followed with serial studies if there is no surgical intervention.
