The most likely diagnosis in a new born who has radio- opaque shadow with an air -fluid level in the chest along in the chest along with hemi-veebra of the 6th thoracic veebra on plain x-ray is-
Bronchogenic cysts are considered as foregut malformations and like the intestinal duplications; they are thought to be derived from an anomalous division of the embryonic foregut. Bronchogenic cysts are rare congenital anomalies that result from abnormal budding or branching of tracheo-bronchial tree. The other broncho-pulmonary foregut malformations include tracheo-esophageal fistula, esophageal diveiculum, esophageal cyst and lung sequestration. Veebral abnormalities (hemi-veebrae) are often associated with bronchogenic cyst of mediastinal origin. Although bronchogenic cysts are usually fluid filled, occasionally a communication may develop following infection or intervention, resulting in air-filled cystic structure or an air-fluid level
