Imaging findings
Post-operative CT after left upper lobe wedge resection and left lower lobe superior segmentectomy in a patient with recurrent adenocarcinoma demonstrates swirling of the bronchovascular bundles at the hilum of the left lower lobe with adjacent consolidation and staple lines from prior resection, raising concern for post-operative lobar torsion.
Key takeaways
Lobar torsion is a rare but life-threatening complication of thoracic surgery in which a residual lobe rotates on its bronchovascular pedicle, causing ischemia. CT demonstrates a swirling pattern of the bronchovascular bundles at the lobar hilum (the whirl sign), consolidation of the torsed lobe, and proximity to the surgical staple line. Prompt recognition and surgical detorsion are essential.
