title: Mediastinal mass and radiolucent esophageal foreign body.
abstract: The diagnosis of radiolucent esophageal foreign bodies can be difficult, particularly in patients with predominant respiratory symptoms. The consequences of the impaction of a foreign body in the esophagus are serious, and esophageal stenosis, perforation, acquired tracheoesophageal fistulas are among the complications already reported. An unusual complication of a nondiagnosed radiolucent plastic coin that remained impacted for 11 months on the posterior esophageal wall of a 20-month-old child, who presented only with respiratory symptoms, is reported. The foreign body eroded through the esophageal wall, causing an intramural abscess that was initially interpreted as a mediastinal mass, and the patient was operated on with the diagnosis of a foregut duplication. Literature on this situation was reviewed, and the problems associated with the diagnosis and treatment of children with radiolucent esophageal foreign bodies are discussed.
