Pulmonary artery sarcoma (PAS) is considered a very rare tumor with a poor prognosis. We herein report two cases of PAS that were diagnosed by positron emission tomography (PET)/computed tomography (CT). In both cases, PET was an effective option for diagnosing tumors, and surgical resection was a valid treatment for these diseases. If a pulmonary artery tumor is suspected, PET/CT is useful for diagnosing PAS and very helpful for choosing the surgical treatment strategy.
