CT pulmonary angiography (CTPA) or chest CT scan before and after therapy in case 1. (A) CTPA demonstrating bilateral pleural effusions and bilateral multiple thrombi in the pulmonary arteries combined pulmonary infarction. (B) Fifteen days after therapy, bilateral thrombi in the pulmonary arteries and pulmonary infarctions significantly decreased. (C) CT scan of the chest showed resolved pulmonary embolism and pneumonia on about 4 months after therapy.

Based on these findings, acute PE was suspected and computed tomographic pulmonary angiography (CTPA) scan was done immediately, which showed bilateral multiple pulmonary artery thrombosis and pulmonary infarction (Fig. 1A). A follow-up CTPA scan, performed 15 days after the initial therapy, revealed the thrombi and pulmonary infarctions had significantly decreased (Fig. 1B). The patient was symptom-free and doing well at about four months of follow-up (Fig. 1C).

On the day of admission, CTPA scan was done and showed multiple filling defects in bilateral multiple pulmonary artery and inferior pulmonary artery (Fig. 2A). About three months after the home treatment, a CTPA scan showed the thrombi in pulmonary arteries resolved entirely (Fig. 2B).
