Abstract
A 56-year-old man with Type 2 diabetes mellitus, in whom diabetes mellitus was detected at the age of 46-years, was admitted on August 5, 1997 because of high fever and left lower abdominal pain. His glycemic control had been poor because he rejected insulin therapy. Abdominal enhanced CT scan and arteriography disclosed an aneurysm of the left common iliac artery. Cultures of blood and stool yielded Salmonella. Therefore, a diagnosis of aneurysm infected by Salmonella was determined. Inflammatory destruction of the entire arterial wall by abscess formation was observed and totally excised, and femorofemoral bypass graft construcion was carried out. Histological examination of the excised aneurysm showed severe atherosclero sis. Infected aneurysm is a comparatively rare disease. In Japan, only 5 cases have been reported in the last 5 years. All cases had arteriosclerotic degeneration and 3 cases had diabetes mellitus. The severe athero sclerotic change in the left common iliac artery and the poorly controlled diabetes may have been related to the Salmonella infection in this case.
