Lung mass compressing pulmonary veins causes pulmonary vein thrombosis and widespread systemic arterial embolization.
Case Report (n=1)
No
Demonstrates that diffuse arterial embolization to multiple organs can be a catastrophic consequence of pulmonary vein thrombosis secondary to lung malignancy.
Highlights potential for catastrophic embolization from lung mass-induced PVT; case report leaves open prevalence and management.
Pulmonary vein thromboses (PVT) is a complication of lung malignancy and can be complicated by arterial embolic phenomenon. Patient is a 69-year-old female with a history of coronary artery disease and recent pneumonia seen on chest x-ray who presented with progressive headache, left arm numbness and abdominal pain. She was found to have numerous bilateral strokes, bilateral renal infarction and splenic infarction. CT Chest showed a right upper lobe mass compressing the pulmonary veins with filling defects concerning for thrombus. Diagnosis of PVT is made with CT angiogram, echocardiogram and MRI. Treatment consists of anticoagulation and treatment of underlying factors.

Plowman et al. (2022) conducted a case report in Pulmonary vein thrombosis (n=1). Pulmonary vein thrombosis was evaluated. A right upper lobe lung mass compressing the pulmonary veins caused pulmonary vein thrombosis and subsequent diffuse arterial embolization including multiple strokes and organ infarctions.
