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
