A–C Transverse axial computed tomography and corresponding pathological basis: A The punctate consolidation in part-solid nodule at the left upper lobe corresponds to tertiary lymphoid structure with a germinal center (red box); B The stripe consolidation in part-solid nodule at the left upper lobe corresponds to fibrotic scar formation without inner tumor cell or invasion observed (red box); C The irregular consolidation in part-solid nodule at the right upper lobe corresponds to invasion with inner acinar structure and lymphocyte clusters observed (red box)
