Severe pulmonary hemorrhage in the right lung
The right lung was markedly hemorrhagic, especially in the hilar region of the middle lobe. The hemorrhagic lesion was extended to both upper and lower lobes (Figure 3). In the last computed radiography (CR) images taken on day 17, four days before the death, hemorrhagic signs were not observed, indicating the hemorrhage occurred during the last three days. The right upper lobe was affected with emphysema, and the lower lobe, subpleural fibrosis. Blood filled most healthy alveoli, indicating the fatality (Figure 4a). The bronchi in the right lower lobe were mildly enlarged, in which coagulants were present (Figure 5ab).
