On CT scans, acute hemorrhage presents as areas of ground-glass attenuation (Cortese et al. 2008) and sometimes consolidations (Fig 9.19b). A “crazy paving” pattern may be seen (Fig. 9.11) (Rossi et al. 2003). The disease evolves rapidly to resolution, at which time small nodules, uniform in size, can be visualized. These represent partial accumulations of hemosiderin and macrophages with hemosiderin.

Despite the fact that the radiographic changes are similar to those of pulmonary edema or an opportunistic infection, pulmonary hemorrhage should be suspected when airspace disease with a rapid evolution is observed, associated with hemoptysis and a low hematocrit value (Table 9.2).
