Figure 2. Enlarged cardiac silhouette with prominent pulmonary
trunk and pulmonary arteries proximally.
A chest CT was done to find out what was causing the high blood pressure
in the pulmonary arteries. The scan showed volume loss in the right
hemithorax. The CT scan also showed a patent ductus arteriosus and an
abnormal origin of the right pulmonary artery from the right ascending
aorta, which has compressed the right main bronchus Figure 3. A
spirometry analysis was avoided due to ongoing hemoptysis and infection.
