Imaging findings
Following bilateral lung transplantation, radiographs showed subtle abnormalities of the pulmonary vessels in the hilum. CT revealed unusual vessels in the left upper lung and features of a pulmonary infarct. The left pulmonary artery was normal in caliber but then abruptly narrowed and twisted, as was the corresponding bronchus. These findings were highly suggestive of lung torsion.
Key takeaways
Lung torsion is a serious complication following lung transplantation, potentially due to rotational misplacement of the lung during surgery, especially in patients with pre-existing fibrosis/low lung volumes. Imaging findings include abnormal vessel and bronchial courses, narrowing of these structures, and potential pulmonary infarct.
