Abstract
A 45-year-old female, who had undergone emergency drainage of a cyst, complained of
severe dyspnea. Chest computed tomography scans showed a large mass, compressing the
right pulmonary artery, superior vena cava, and tracheal bifurcation. Subtotal resection
of the cyst wall was carried out due to dense adhesion to adjacent structures. Immediately
after surgery, her symptoms resolved completely. Mediastinal bronchogenic cysts in
the subcarinal space can cause severe respiratory distress from airway and vascular
compression.
Key words
Thoracic surgery - respiratory distress - subcarinal - bronchogenic cyst
