Pathological findings
Autopsy was performed 8 hours 20 min after his death. The height 177 cm and weight 92 kg indicated obesity (BMI 29.4). Operation scar for lung cancer was present in the left lateral side of his chest, as well as multiple insulin-injection scars in his abdomen.
Pulmonary pathology
Macroscopically, both lungs were hardened, weighed 800 g (right upper, middle, and lower lobes) and 260 g (left lower lobe)(Figure 2a). The right lung was markedly hemorrhagic, especially in the middle lobe. The upper lobe of the left lung was missing, due to lobectomy for lung cancer. The cut surfaces of post-mortem lungs were compared with the last CT image taken on day 8 (Figure 2b)(Supplement figures 1-3)
