Figure 8a. Apical RILD due to supraclavicular radiation therapy in a 42-year-old woman with adenocarcinoma of the right breast (same patient as in Fig 5). (a) CT scan obtained 4 months after completion of radiation therapy shows ground-glass attenuation and nodular areas of increased attenuation in the right upper lobe, findings indicative of radiation pneumonitis. (b) CT scan obtained 16 months after completion of radiation therapy shows organization of the apical radiation pneumonitis into fibrosis.
