title: Ectopic gastric duplication cyst in an infant.
abstract: A case of an ectopic gastric duplication cyst that appeared to arise from the pancreas in a 10-week-old infant with a superficial mass in the left upper quadrant is reported. Preoperative ultrasound showed a cystic lesion with an inner echogenic layer (mucosa) and an outer anechoic rim (muscle). Technetium scan demonstrated that there was a gastric-type mucosa in the cyst. It is suggested that the ultrasound findings are specific for a gastric duplication cyst and that ultrasound and technetium scan alone will adequately characterize these lesions preoperatively.
