Abstract

The variable sonographic appearance of duplication cysts is presented. Eighteen sonograms from 14 patients, aged 1 day to 8 years, were reviewed over an 8 year period. Water and other aqueous contrast agents were used in six patients as part of the sonographic evaluation. All lesions were confirmed by surgery. All but two patients were symptomatic. Twenty-four cysts were detected, ranging in size from 1.7 to 15.5 cm. The duplication cysts revealed a spectrum of sonographic findings (cystic to solid appearing masses). The mass characteristics, including the "muscular rim sign," and internal debris or hemorrhage, were demonstrated. Multiple unsuspected cysts (3 of 14 or 20%) and complications such as perforation were readily seen with ultrasonography. 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 muscular 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.
