Gender M, male; F, female; LUL, left upper lobe; RLL, right lower lobe; RUL, right upper lobe; RML, right middle lobe; CT, computed tomography; EBUS, endobronchial ultrasound; Sq, squamous cell carcinoma; Ad, adenocarcinoma; 4D-ENB, four-dimensional tracking electromagnetic navigation bronchoscopy. ^aIn all patients, EBUS findings were concordant between the conventional bronchoscopy and the 4D-ENB phases; ^bThe nodule diminished in size during two years of CT follow-up.
