Primary angiosarcomas of the aorta are rare, highly aggressive malignant tumors for which there have been limited documented cases in the medical literature. Diagnosis is challenging due to nonspecific symptomatology and imitation of common aortic pathologies. A subset of these primary aortic angiosarcoma cases is seen in association with endovascular aneurysm repair, or EVAR; however, the connection between the 2 entities is not completely understood. Here, we present 18F-FDG PET/CT imaging findings of an angiosarcoma of the aorta in a 69-year-old man status post EVAR.
