Duplication cyst of the esophagus: A rare congenital cause for vomiting and respiratory distress

A duplication cyst of the esophagus is the 2ndmost common congenital anomaly of the gastrointestinal tract. Although these benign cystic masses can be picked up routinely on a chest X-ray, patients may experience symptoms such as stridor or dysphagia corresponding to lesions within the neck or mediastinum. We present a rare case of a duplication cyst of esophagus in a 2-week-old female baby, which was surgically excised. Our aim in this case report is to raise awareness of this congenital disorder; especially when differential diagnoses such as acute respiratory distress syndrome (ARDS), failure to thrive, asthma, pneumonia, neuromuscular disorders and suspected foreign body inhalation have been ruled out in the pediatric patient.
