Figure 4 Eosinophilic granulomatosis with polyangiitis. A 53-year-old female with history of asthma presented with shortness of breath. A: Computed tomography of the chest at baseline shows poorly defined, randomly distributed areas of airspace ground glass opacity (arrows); B: Follow-up computed tomography after 4 mo demonstrated persistent but improved areas of ground glass opacity in a slightly different distribution than in the baseline image (arrows).
