Foregut Duplication Cysts in a Patient With Congenital Diaphragmatic Hernia: A Case Report

Esophageal duplication cysts are a rare form of foregut developmental abnormality with heterogeneous manifestations due to their variable location and size. Congenital diaphragmatic hernia is a congenital defect resulting from incomplete diaphragm formation, with a wide spectrum of severity. It is typically diagnosed antenatally and managed surgically in the neonatal period. We present a case report of a newborn with a rare co-occurrence of congenital diaphragmatic hernia and multiple esophageal duplication cysts.
