Imaging findings
A patient exhibited classic signs of chronic pulmonary thromboembolism, including a substantial burden of occlusive organized thrombus within the left lower lobe pulmonary arteries. Lung windows demonstrated mosaic oligemia, narrowed vessels, evidence of prior pulmonary infarcts, and a cavitary lesion, likely a cavitated infarct.
Key takeaways
Chronic pulmonary thromboembolism (CTEPH) is characterized by chronic, organized thrombus within the pulmonary arteries, leading to pulmonary hypertension, mosaic oligemia, and variable findings such as infarcts or cavitary lesions. Pulmonary endarterectomy is a surgical option for carefully selected patients, aiming to remove the organized material and restore pulmonary blood flow.
