Left upper lobe and lingula torsion after transplantation of single lung with complete major and minor fissures: A case report

•Presence of complete major and minor fissures can increase the risk of torsion.•CT and/or CTA are useful modalities to detect lung torsion.•Lack of contrast in pulmonary vessels, high-grade narrowing of bronchus, abnormal location of segment are imaging findings.•Anatomical defects in transplanted lungs plus significant manipulation during surgery can increase the risk of torsion.
