The chest X-ray showed an infiltrative shadow in the left lower lung field and chest CT revealed the consolidation along with ground-glass opacity in the both lung fields and pleural effusion (Fig. 1a and b).
The contrast CT one week after admission revealed deterioration of pleural-based infiltrative shadows and ground glass opacity (arrow) with poorly enhanced lung parenchyma (arrowhead). Multiple thromboses were detected in pulmonary arteries (circle). The increase of pleural effusion was seen in both lungs.

The contrast CT one week after admission showed the deterioration of infiltrative shadows and pleural effusions with thromboembolism in pulmonary arteries, suggesting pulmonary infarction (Fig. 2).
