Imaging findings for both of the lung metastases. Computed tomography showed a 5-mm-sized frosted glass shadow in the right lung apex (a), and a 5-mm-sized node from the left superior mediastinum to the ventral pleura in the left lung (b) 42 months after first resection. Forty-six months after first resection, the right lesion changed to a nodule and expanded to 10 mm (c), the left lesion disappeared (d). Both the right (e) and left lesions (f) indicated growth again 50 months after first resection. The size of both tumors, the right (g: white arrow) and left lesion (h: white arrow) had increased to 20 mm right before resection 54 months after first resection
