Key result
Aortic resection with Dacron prosthetic graft replacement in a 74-year-old female revealed an unexpected diagnosis of aortic mural sarcoma, which had masqueraded as a mycotic aneurysm.
Why the study?
Preoperative diagnosis of aortic sarcoma is often difficult due to its rarity and can present diagnostic pitfalls.
Case Report (n=1)
Aortic sarcoma is a rare primary tumor that can mimic a mycotic aneurysm, highlighting diagnostic pitfalls in preoperative imaging.
Aortic sarcoma may mimic mycotic aneurysm with rapid growth; case report leaves open improved preoperative differentiation.
Aortic sarcoma is a rare primary tumor with dismal prognosis. Here, we report a case involving a 74-year-old female patient with aortic sarcoma masquerading as a mycotic aneurysm in the thoracoabdominal aorta. She underwent aortic resection with Dacron prosthetic graft replacement because of rapid growth. The postoperative pathological findings of the resected specimen confirmed the diagnosis of aortic mural sarcoma, which was an unexpected result based on repeat computed tomography angiography performed within 2 months preoperatively. The preoperative diagnosis of aortic sarcoma is often difficult because of its rarity, and this case demonstrates some of the diagnostic pitfalls
