CTICasesLobar torsion secondary to pneumonia
Imaging findings
CT scan shows rotation of the left upper lobe consolidation anteriorly and inferiorly, with narrowing of the left upper lobe bronchus and pulmonary vessels, in a patient with complete pleural fissures.
Key takeaways
Lobar torsion can complicate acute pneumonia or pleural effusion. The increased weight of the consolidated lobe combined with a complete pleural fissure allows the lobe to rotate on its pedicle, which requires urgent surgical detorsion or resection if ischemic.
