Key result
A 78-year-old man evaluated for a persistently enlarging abdominal aortic aneurysm after endovascular repair was found to have a rare pleomorphic undifferentiated aortic sarcoma.
Why the study?
Aortic sarcomas are rare malignant neoplasms often diagnosed at an advanced stage with symptoms mimicking nonmalignant vascular disease.
Case Report (n=1)
Aortic sarcomas can mimic nonmalignant vascular diseases such as persistent endoleak after EVAR, highlighting the need for careful diagnostic workup in atypical presentations.
Atypical post-EVAR aneurysm growth may indicate sarcoma; this case leaves open optimal diagnostic strategies for rare mimics.
Sarcomas of the aorta are rare tumors with an unknown incidence and wide variety of clinical presentations. These malignant neoplasms are often manifested in an advanced state and with symptoms of nonmalignant vascular disease owing to a delay in diagnosis. We present the case of a 78-year-old man in whom workup was initially performed for a persistently enlarging abdominal aortic aneurysm after endovascular aortic repair but who was subsequently found to have a pleomorphic undifferentiated sarcoma of the aorta.

Whittington et al. (2019) conducted a case report in Pleomorphic undifferentiated aortic sarcoma (n=1). Diagnostic workup was evaluated on Diagnosis of pleomorphic undifferentiated sarcoma of the aorta. A 78-year-old man evaluated for a persistently enlarging abdominal aortic aneurysm after endovascular repair was found to have a rare pleomorphic undifferentiated aortic sarcoma.
