Key result
Surgical resection of a rapidly growing iliac artery mass initially diagnosed as a mycotic aneurysm revealed an undifferentiated intimal sarcoma, and the patient died 2 months later.
Why the study?
Intimal sarcoma of arteries is a rare malignant tumor that often mimics other vascular disorders, making preoperative diagnosis challenging.

Vascular surgeons should consider intimal sarcoma in the differential diagnosis for patients with atypical vascular masses mimicking mycotic aneurysms.
Intimal sarcoma may mimic rapidly growing mycotic iliac aneurysms; this case leaves open refined preoperative diagnostics.
Intimal sarcoma of arteries is a rare malignant tumor, which often mimics other vascular disorders; therefore, preoperative diagnosis is often challenging. We herein report a 71-year-old man who presented with fever and elevated inflammatory markers who had a mass in the left internal iliac artery with rapid growth. Based on clinical findings, a diagnosis of mycotic aneurysm was made. We performed surgical intervention, including resection of the affected vessels with omentopexy, although intraoperative findings were not typical of a mycotic aneurysm. Microscopic and immunohistochemical examination demonstrated undifferentiated intimal sarcoma. The patient died of multiorgan failure two months after the surgery. The vascular surgeon should consider the possibility of a diagnosis of intimal sarcoma for patients with atypical findings and the importance of histological and immunohistochemical examination for precise diagnosis in surgical vascular cases.

Seo et al. (2019) conducted a case report in Undifferentiated intimal sarcoma (n=1). Surgical resection with omentopexy was evaluated on Clinical outcome. Surgical resection of a rapidly growing iliac artery mass initially diagnosed as a mycotic aneurysm revealed an undifferentiated intimal sarcoma, and the patient died 2 months later.
