A Case of Radiation Fibrosis Appearing as Mass-Like Consolidation after SBRT with Elevation of Serum CEA

<table>Serial changes of serum CEA, KL-6, and SP-D. (1) At 12 months after SBRT, mass-like consolidation appeared in the irradiated area. (2) At 15 months, the mass-like consolidation enlarged at the dorsal side and serum CEA increased accompanied by KL-6 and SP-D. (3) At 16 months, serum CEA was slightly decreased. (4) At 31 months, minimal lung opacities suggesting pneumonia in the left lower lobe were observed on CT images, but no significant change was seen in the irradiated area.</table>
