bronchogenic cyst

abnormality of primitive foregut (ventral segment = tracheobronchial tree; dorsal segment = esophagus)

  • lined with columnar respiratory epithelium
  • CT: water density (50%); higher density (50%); may have air/fluid level

  • mediastinal brochogenic cyst (86%)
    • associated with spinal abnormalities
    • M:F = 1:1
    • stridor, dysphagia; usually assymptomatic
    • may communicate with tracheal lumen
    • location: posterior mediastinum (50%), pericarinal (35%), superior mediastinum (14%); usually on right

  • intrapulmonary bronchogenic cyst (14%)
    • M>F; LL:UL = 2:1 (usually medial third)
    • infection (75%), dyspnea, hemoptysis
    • 36% will eventually contain air
