Intravascular Epithelioid Angiosarcoma in the Abdominal Aorta Mimicking an Infected Aneurysm
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.
