Figure 1. Chest CT scans and pathological result. A: only a right lower lobe inflammatory focus can be found. The chest CT scan was performed at the same time the eight cancer-driven mutations were detected (May 2017); B: the enlarged lymph nodes under the aortic arch can be seen, and a shadow of soft tissue around the aortic arch of the left lower lobe probably reflects a malignant lesion (January 2018); C, D: morphological results reflect the possibility of small cell lung cancer. Scale bar: 400 µm (C); and 200 µm (D)
