Extensive acute pulmonary thromboembolism with thromboemboli present within the distal right and left main pulmonary arteries, bilateral ascending lobar and descending interlobar arteries with extension to involve the segmental branches. There is a combination of occlusive and non-occlusive thromboemboli. There is pulmonary arterial hypertension with right ventricular strain, however, no IVC or intrahepatic reflux. The main pulmonary arterial trunk is unaffected with normal opacification of the right heart.
The lung fields are clear with no groundglass opacities, no pulmonary infarcts and no effusions.
CTPA is otherwise unremarkable.
