Infected esophageal duplication cyst simulating empyema.

Duplications of the esophagus are the second most common duplication of the gastrointestinal tract. The children with esophageal duplication cyst usually present with respiratory distress or as asymptomatic thoracic mass found on incidental chest x-ray. We report a case of infected esophageal duplication cyst initially confused with empyema in a two years old boy.
