RP in a 64-year-old man with squamous cell cancer. (A, B) Axial pretreatment CT images show a nodule (arrow in A) in the right upper lobe and ground-glass abnormality (arrowheads) in the subpleural area, suggesting ILA. (C) Axial CT image after radiation therapy shows ground-glass abnormality and consolidation (arrows) in the right lung, beyond the irradiated field. The patient required steroid therapy for RP.
