Congenital esophageal duplication cyst: A rare cause of infantile stridor and a diagnostic challenge

Abstract

Duplication cyst of the cervical esophagus represents a rare congenital anomaly. The children with esophageal duplication cyst usually present with respiratory distress or as asymptomatic thoracic mass found on incidental chest X-ray. We here present a case of a 3-month-old male infant who presented with noisy breathing and progressive respiratory distress and with no other abnormality. After laryngoscopy, barium esophagography and MRI study, congenital esophageal duplication cyst was diagnosed. Transcervical excision of the cyst was done using a harmonic scalpel. Histopathological examination of the specimen confirmed the diagnosis. The patient remains asymptomatic after one year of follow up.
