Mediastinal Cysts and Duplications in Infants and Children

Priscilla Chiu, Jacob C. Langer

Key Points

  • Cystic lesions in the mediastinum are uncommon in infants and children
  • Most cystic lesions in infants and children are benign
  • Symptoms from the cystic lesions arise from mass effect on adjacent structures or infectious and inflammatory complications
  • Complete surgical excision is required for any symptomatic mediastinal cyst unless there is a common wall to the airway or esophagus of a foregut cyst
  • Prenatal diagnosis of cystic lesions warrant consultation with a multi-disciplinary team, especially for cases involving fetal distress
