Key result
Staged hybrid surgery was performed for a suspected mycotic aortic aneurysm that was pathologically confirmed as aortic intimal sarcoma, with the patient dying of sepsis 2 years later.
Case Report (n=1)
Aortic intimal sarcoma is a rare malignancy that can mimic a mycotic para-renal abdominal aortic aneurysm and carries a poor prognosis despite surgical intervention.
Consider intimal sarcoma in atypical para-renal aneurysms; this Level 5 case leaves open optimal management strategies.
We present a case of aortic intimal sarcoma mimicking a mycotic para-renal abdominal aortic aneurysm, treated with staged hybrid surgery. A 60-year-old female presented with complaints of nausea and back pain. Computed tomography showed a para-renal abdominal aortic aneurysm with irregular and multilobulated shape, without periaortic soft-tissue inflammation, occlusion of the celiac artery, and stenosis of the superior mesenteric artery. She underwent superior mesenteric artery stenting, followed by aortic resection and axillo-femoral bypass for suspicion of mycotic aortic aneurysm. Pathologic examination revealed aortic intimal sarcoma. Two years after surgery, she died of multiple organ failure due to sepsis during chemotherapy for bone metastases.

Kasa et al. (2025) conducted a case report in Aortic intimal sarcoma mimicking a mycotic para-renal abdominal aortic aneurysm (n=1). Staged hybrid surgery (superior mesenteric artery stenting, aortic resection, and axillo-femoral bypass) was evaluated. Staged hybrid surgery was performed for a suspected mycotic aortic aneurysm that was pathologically confirmed as aortic intimal sarcoma, with the patient dying of sepsis 2 years later.
