A Case of Imflammatory Abdominal Aortic Aneurysm / 日本心臓血管外科学会雑誌

ABSTRACT

A 78-year-old man consulted our hospital with complaint of abdominal mass. Blood examination indicated a inflammatory reaction. An abdominal aortic aneurysm, 5.5cm in size, was found by CT scanning examination. Its wall quite thick (mantle sign), and enhanced by contrast medium. Y graft replacement was carried out. Microscopic hiatological examination of the aneurysmal wall indicated severe inflammation being assisted of chronic inflammatory cells, like lymphocytes and plasma cells at the adventitia. Ten cases of inflammatory abdominal aortic aneurysm reported in Japan so far are reviewed and features of this disease are discussed.
