(2) Multiple, patchy or large patches of consolidation in both lungs, with a little grid-like or honeycomb-shaped interlobular septal thickening, especially in the middle and lower lobes (Fig. 3: 26 cases, 31.3% in a total of 83 cases). It was more common in the elderly or severe condition patients. Fig. 3 Typical CT / X-ray imaging manifestation (case 3). A 65 years old male with fever for 4 days (38.7 ℃). Laboratory test: normal white blood cells (3.72 × 109/L), decreased lymphocytes (0.9 × 109/ L), decreased eosinophil count (0 × 109/L), increased C-reaction protein (53.0 mg/L), increased procalcitonin (0.10 ng/ml), reduced liver function, hypoproteinemia, and mild anemia. Imaging examination: a and b showed large consolidation in the right middle lobe, patchy consolidation in the posterior and basal segment of the right lower lobe, with air-bronchogram inside, c showed patchy consolidation in the outer and basal segment of the left lower lobe, and a small amount of effusion in the right chest
