Prenatal ultrasonic diagnosis of congenital duplication of the stomach.
A case of gastric duplication cyst first visualized sonographically in the prenatal period is described. The prenatal identification of abnormality allowed prompt postdelivery diagnosis and surgical treatment. The characteristic location of this cyst is in the right upper quadrant of the fetal abdomen. The presence of peristalitic activity within the cyst can point to a gastrointestinal origin. A hypoechoic outer rim and hyperechoic inner rim also suggests the stomach as the etiologic origin of the cyst. With this entity, the presence of associated congenital anomalies should be sought. No known associated genetic chromosomal anomalies are reported.
