Illustration of the localisation procedure in patient 5. A A computed tomography image showing a nodule (yellow arrow) in the right upper lobe. B Three-dimensional computed tomography lung reconstruction showing that the nodule is located in the upper lobe of the right lung, far from the pleura, but that the projection position of the nodule on the lung surface is approximately the middle of the upper and lower boundaries. Three-dimensional computed tomography bronchography and angiography suggest that the nodules are located at the apical segment of the right upper lobe but close to the posterior segment. C Localisation is based on the distance between the nodule and the upper and lower boundaries and a burn mark made with an electrotome. D The resected specimen after apical segmentectomy shows adequate surgical margins (arrow). The final histology confirmed this lesion to be minimally invasive adenocarcinoma
