Figure 10. Bleomycin-induced organizing pneumonia in a 44-year-old woman with Hodgkin lymphoma who presented with a nonproductive cough, dyspnea, and decreased DLCO. High-resolution CT scan shows ground-glass attenuation and scattered areas of focal consolidation peripherally. Note the intralobular lines superimposed on the ground-glass attenuation. The diagnosis of organizing pneumonia was confirmed with transthoracic biopsy; there was improvement in the symptoms and radiologic findings after discontinuation of the bleomycin therapy and initiation of corticosteroid therapy.
