Primary aortic angiosarcoma is very rare, and preoperative diagnosis is challenging with resultant poor prognosis. Angiosarcoma may mimic an infected aneurysm or a mural thrombus. Clinical suspicion of angiosarcoma is vital for an early diagnosis and proper surgical treatment, especially in cases with atypical rapid growth of an aortic abdominal aneurysm with a thrombotic mass. Herein, we report a case of angiosarcoma in the abdominal aorta mimicking an infected aneurysm and present computed tomography and positron emission tomography findings.
