A 2.5-year-old boy with noisy breathing and recurrent chest congestion for 9 months, presented inspiratory stridor and decreased air entry in the middle zone of the left hemithorax. Chest radiography showed a cavity with an air-fluid level in the left lung parenchyma and deviation of the trachea to right (Figure 1). Computed tomography of the chest and neck showed a well-defined air-containing cystic mass with high attenuation in the left lung, and a cystic lesion in the left side of the neck and superior mediastinum, compressing the trachea (Figure 2). Laboratory tests were normal. Both cysts were excised without damaging the lung parenchyma in case of intrapulmonary cyst, and without opening the esophageal mucosa in case of intralum-inal cervical esophageal cyst. The pathological diagnosis was intrapulmonary bronchogenic cyst and duplication cyst of the esophagus.
