Patient Data

Age: 38 years
Gender: Male

A hypoattenuated nonenhancing intraluminal thrombus measuring 6.1x1.7cm in the right pulmonary artery extending from the bifurcation of the pulmonary trunk to the lower lobar segmental branches. The thrombus is resulting in subtotal ( > 80-85% ) luminal obstruction.

A soft tissue attenuation nodular lesion with cavitation is noted in the subpleural region of superior basal segment of right lower lobe lobe representing pulmonary infarct with secondary infection.

The diameter of main pulmonary trunk exceeds the diameter of aortic arch.

Imaging features are suggestive of chronic pulmonary artery thromboembolism with pulmonary infarct and possible pulmonary artery hypertension.

Case Discussion

Pulmonary thromboembolism is potentially life threatening however curable condition. Early diagnosis and treatment improves the outcome. Cross sectional imaging is mainstay of diagnosis.
