Two months after surgery, the patient developed fever, high C-reactive protein levels, anemia, a persistent productive cough, and hemoptysis. Furthermore, he experienced a left-sided pneumothorax that was not treatable with pleural tubes alone (Fig 3), and was then referred to the university hospital. Upon arrival at the Department of Pulmonary Medicine, the patient was in a generally poor condition, and a chest CT scan demonstrated large, abscess-like structures in the right lung (Figs 4, 5). The erythrocyte sedimentation rate was 36 mm/h (normal range, 1-12 mm/h); C-reactive protein level, 80.5 mg/L (normal range, 0.0-4.0 mg/L); hemoglobin level, 9.3 g/100 mL (normal range, 13.4-17.0 g/100 mL); WBC count, 12.0 × 109/L (normal range, 3.5 × 109-10 × 109/L), D-dimer level > 4.0 mg/L (normal range, 0.0-0.4 mg/L); and platelet count, 503 × 109/L (normal range, 145 × 109-390 × 109/L). The patient’s body temperature was 38.6°C, and oxygen saturation was 98%.
