Cryptogenic organizing pneumonia (COP) pattern of radiation pneumonitis (grade 2) in a 63-year-old male with non-small cell lung carcinoma, treated with chest radiotherapy using 3-dimensional conformal radiotherapy (3DCRT). Axial chest computed tomography (CT) at the time of symptomatic radiation pneumonitis demonstrated multifocal patchy ground glass and reticular opacities in the left lung (arrows), representing a radiographic COP pattern. The patient presented with shortness of breath and wheeze which responded to steroid therapy.
