Figure 10 Pneumocystis jirovecii infection. A 43-year-old man with human immunodeficiency virus infection who presented with shortness of breath and fever. A: Contrast-enhanced computed tomography of the chest in lung window at presentation showed extensive ground glass opacity in both lungs, with a more focal consolidative opacity in the left lung (arrow); B: Follow-up computed tomography 3 mo after treatment showed improvement in ground glass opacity, with residual interlobular septal thickening and the ground glass opacity causing crazy paving appearance (arrows).
