Abstract

An esophageal duplication cyst (EDC) is a congenital anomaly of the foregut. EDCs are often asymptomatic, so they are found incidentally on chest radiographs. In symptomatic patients, EDCs present with cough, dyspnea, vomiting, dysphagia, and chest pain. Potential complications of EDCs include perforation, obstruction, bleeding, and infection. The rarity of this condition may hinder timely diagnosis, which may lead to life-threatening complications. This article describes a case of esophagitis and mediastinitis developed in a 12-month-old infant with an EDC. We emphasize that although rare, EDCs should be considered in the differential diagnosis of non-specific respiratory signs such as cough, dyspnea, and stridor.
