Imaging findings
Post-right upper lobectomy, the right middle lobe failed to expand. CT showed an incomplete torsion with subtle twisting and narrowing of the right middle lobe pulmonary artery, while the pulmonary vein remained patent. The lobe was volume expanded and boggy, rather than atelectatic.
Key takeaways
Lung torsion post-lobectomy is a rare but serious complication. Imaging findings can include failure of the remaining lobe to expand, twisting of pulmonary vessels, and a volume-expanded, boggy appearance of the affected lobe rather than atelectasis. Prompt recognition and surgical detorsion can salvage the lung.
