<i>In utero</i> sonographic appearance of intestinal duplication cysts

Abstract

The antenatal appearance of gastrointestinal duplication cysts is described. Two cases are presented: a duplication cyst of the pylorus and a cyst of the terminal ileum. The embryogenesis and the clinical utility of prenatal diagnosis of these malformations of the alimentary tract are discussed. Antenatal detection of these cystic masses allowed close neonatal surveillance and timely surgical intervention prior to neonatal complications.
