(A-D) High-resolution computed tomography (HRCT) reveals four ground glass opacity (GGO) lesions of patient 1 (a 3.2×1.5 cm lesion located at the apical segment of the right upper lobe, a 1.3×1.0 cm lesion located at the posterior segment of the right upper lobe, a 1.0×0.8 cm lesion located at the apical segment of the left upper lobe, and a 0.8×0.8 cm lesion located at the posterior basal segment of the left lower lobe); (E,F) HRCT reveals two tumor-like lesions of patient 2 (a 3.0×2.5 cm mass located at the posterior segment of the right upper lobe and a 1.6×0.9 cm GGO lesion located at the superior segment of the left lower lobe); (G) surgical image of instrumentation during right upper lobectomy.
