CTICasesDynamic Expiratory Air Trapping post-Lung Transplant
Imaging findings
Dynamic expiratory CT in a patient post-unilateral lung transplant for constrictive bronchiolitis shows a normal functioning left donor lung and a hyperexpanded, non-perfused right native lung showing severe air trapping and lack of ventilation.
Key takeaways
Unilateral lung transplantation for obstructive diseases leaves the diseased native lung in place. Expiratory CT is useful for demonstrating severe air trapping, shift of the mediastinum towards the donor lung, and lack of native lung ventilation.
