case_images: A nodule in the upper posterior lobe of the contralateral lung, of 27 mm, was also identified (Figure 1).
case_images: PET at first staging.. Note: The images confirm the nodular lesions in both lungs as stage T3 N0 M1a.

case_images: Stage of disease was T3 N0 M1a (Stage IV) according to American Joint Committee on Cancer (AJCC) seventh edition (Figure 2).
case_images: PET at first restaging after chemotherapy.. Note: The disease is downstaged with persistence of primary tumor in right lung: the stage is yT2 N0 M0.

case_images: The disease was downstaged to yT2a N0 M0 (stage IB) due to disappearance of the two nodules (Figure 3).
case_images: CT/PET at second restaging after thoracic radiotherapy (66 Gy dose delivered).. Note: The findings of post-radiation pneumonitis and persistent disease are recorded.

case_images: The PET after 3 months of radiotherapy showed a metabolically active right pulmonary lesion with avid FDG uptake (SUV 14) (Figure 4).
case_images: PET at last restaging after eight cycles of nivolumab.. Note: No fluorodeoxyglucose uptake and cavity with fibrosis in right lung is present, confirming a complete remission of disease.
