CTICasesPost-Pneumonectomy Syndrome
Imaging findings
CT chest in a patient post-right pneumonectomy shows extreme rightward mediastinal rotation/shift. The left main bronchus is severely compressed and flattened against the spine. Companion case shows normal post-pneumonectomy positioning.
Key takeaways
Post-pneumonectomy syndrome is a late complication where the mediastinum rotates (hinging on the descending aorta) into the empty space, causing mechanical compression of the contralateral main bronchus against the vertebral column.
