Plain-English summary
A 9-year-old mixed-breed dog was diagnosed with a rare type of cancer called pulmonary artery sarcoma, which was blocking blood flow in the right pulmonary artery. The dog showed signs of severe heart and breathing problems, leading to advanced imaging tests that revealed a large mass and other serious changes in the heart and lungs. Unfortunately, despite the findings, the dog passed away, and a postmortem examination confirmed the presence of the cancer and its spread to other organs. This case highlights the importance of imaging in diagnosing complex heart and lung issues in dogs.

Abstract
Intravascular pulmonary artery sarcomas in combination with myocardial metastasis are rare in dogs. We describe the radiographic, echocardiographic, and electrocardiographic-gated (ECG-gated) computed tomographic angiography (CTA) findings in a dog with pulmonary artery sarcoma. All imaging studies demonstrated severe main pulmonary artery enlargement. Echocardiography and ECG-gated CTA revealed a mass occluding the lumen of the right pulmonary artery. In addition, CTA revealed focal left ventricular myocardial contrast enhancement and parenchymal lung changes. Postmortem examination confirmed the presence of a large thrombus associated with arteriosclerosis and an intravascular sarcoma in the right pulmonary artery with metastases to the myocardium, lungs and brain.
