MYCOTIC-ANEURYSM OF THE THORACIC AORTA CAUSED BY CLOSTRIDIUM-SEPTICUM

We describe a case of a 78-year-old man who presented with a mycotic a neurysm of the thoracic aorta caused by Clostridium septicum and under went successful resection. There are only 3 cases of mycotic aneurysms caused by Clostridium septicum reported in the literature. Clostridiu m septicum infections have been shown to have a high association with gastrointestinal and hematologic malignancies. AII patients with Clost ridium septicum infections, therefore, require a search for gastrointe stinal lesions, as they may represent a source of persistent bacteremi a. This patient had no malignant lesions but did have multiple benign sigmoid polyps.
