a Chest computed tomography shows a large bulla in the right segment 8 (open diamond) and a smaller bulla in segment 6 (*) located in contact with the intermediate bronchial trunk (IBT). A schema represents the anatomical position of the IBT and the energized area of the bulla in the right segment 6. b Thoracoscopic review of the bulla cauterization. The giant bulla in the right segment 6 was cauterized using soft coagulation system. RLL right lower lobe
