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).
