Duplication cyst of oesophagus: a case report.

Duplication of the oesophagus is the second most common duplication of the gastrointestinal tract. Children with oesophageal duplication cyst usually present with dysphagia or as asymptomatic thoracic mass found o incidental chest x-ray. We report a case of oesophageal duplication cyst that presented with inspiratory stridor and dyspnoea in a 6 month old boy. Bronchoscopy revealed an external compression on the trachea. Duplication cyst arising from the oesophagus was suggested on CT and MRI. The cyst was surgically excised with resolution of symptoms.
