Synonyms
- Foregut/midgut/hindgut malformation or duplication, enteric cyst, enterocyst, enterocystoma, enterogenous cyst, dorsal enteric cyst, alimentary tract duplication (ATD)
Definitions
- GI duplication cysts have 3 defining characteristics
- Well-developed coat of smooth muscle
- Epithelial lining representing some part of GI tract
- Attachment to (± communication with) GI tract
- Isolated cysts: No longer attached (extremely rare)
- Neurenteric cysts often have associated vertebral & intraspinal anomalies
- Most frequent with esophageal duplications
- GI duplication cysts have 3 defining characteristics
