Right upper-lobe non-small cell lung cancer

(A) CT of a 76-year old male, former smoker with a 19 mm right upper-lobe non-small cell lung cancer. Due to an FEV1 of 0.65 L (23% predicted) and a DLCO of 5.6 (23% predicted), he was not offered surgery and underwent SBRT (5 fractions, 6000 cGy).
(B) CT one year post SBRT with postradiation changes but no evidence of recurrence.
