CTICasesSpontaneous Lobar Torsion
Imaging findings
Right upper lobe shifted to the inferior chest, confirmed by bronchus malposition on CT and narrowing of a branch of the right superior pulmonary vein on CTA, suggesting venous obstruction.
Key takeaways
Lobar torsion can occur spontaneously without prior surgical intervention. Imaging clues include abnormal bronchial orientation and twisting vessels, which may lead to venous or arterial infarction.
