- Abstract: A 77-year-old woman underwent endovascular abdominal aortic repair (EVAR) for an abdominal aortic aneurysm (AAA)．Five years after surgery, she visited the hospital with the chief complaint of a fever. Enhanced computed tomography (CT) showed enlargement of the AAA around the stent-graft and a mass, which was suspected to be an abscess, outside the aneurysm. A blood test revealed a high level of inflammatory response. The patient was diagnosed with infectious AAA. She received antibiotics; however, the inflammatory response did not completely improve. A second CT scan revealed that the suspected abscess had a spreading tendency. The patient was referred to our hospital for a highly suspected stent-graft infection. We performed Y-graft replacement using a rifampicin-immersed graft, and as much as possible of the wall around the aortic aneurysm was removed. The inflammatory response improved rapidly after the operation, and the patient was discharged 15 days later. According to the results of a pathological examination, a diagnosis of xanthogranulomatous inflammation and fibrosis was made. Here, we report a rare case of xanthogranulomatous inflammation of the aortic aneurysm wall after EVAR.
