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
