Chronic airspace disease: Review of the causes and key computed tomography findings

Figure 17 Pulmonary hemorrhage. A 48-year-old woman with antiphospholipid antibody syndrome presented with shortness of breath. A: Computed tomography showed patchy, predominantly ground glass opacities in both lungs, with areas of subpleural sparing (arrows) that were confirmed to be due to alveolar hemorrhage; B: At 6 mo later, the patient presented with worsening dyspnea and hemoptysis and computed tomography demonstrated significant interval worsening of ground glass opacities with new involvement of a majority of the lung parenchyma.
