Lung torsion is a rare but life-threatening event, with a reported incidence of 0.089% - 0.4%. The first review article on this topic, published in 2016, cited middle lobar torsion after upper lobectomy as the most common scenario. We report a case of postoperative right middle lobar torsion in a 60-year-old man following elective right upper lobectomy for underlying lung adenocarcinoma. A diagnosis based on chest X-ray and bronchoscopy was made on postoperative Day 5. An emergent thoracoscopic detorsion surgery, which was performed immediately after diagnosis, failed to restore lung viability. The patient then underwent middle lobe resection from which he recovered uneventfully. He was discharged on the thirteenth day after re-operation.
