Why the study?
Primary osteogenic sarcoma in the pulmonary artery is extremely rare and presents like pulmonary thromboembolism, with few studies describing its radiographic characteristics.
Multimodality imaging is crucial for accurately diagnosing and characterizing rare primary pulmonary artery osteosarcomas that can mimic pulmonary thromboembolism.

PA osteosarcoma mimicking PE may warrant multimodality imaging in atypical cases; leaves open standardized diagnostic criteria.
Primary pulmonary artery sarcoma (PAS) is an extremely rare malignant disorder that presents like pulmonary thromboembolism (PE). Primary osteogenic sarcoma in the pulmonary artery (PA) is even rarer and can produce osteoid or cartilaginous matrix. Few studies have described the radiographic characteristics of osteosarcoma of the PA. We there report a case of a 78-year-old male patient with osteosarcoma in the PA where the patient went through surgical treatment after careful multimodalityimaging assessment. The patient was admitted to our hospital with the nonspecific symptom of heart failure. Multimodality imaging showed the primary lesion adhering to the arterial wall but without invading into surrounding tissues. PET/CT showed signs of hypometabolic activity within the lumen of the main PA. Cardiac MRI showed preserved left ventricular systolic function. CT showed distinctive features of PA osteosarcoma (a slightly hyperdense mass with calcification in pulmonary trunk).
