Suprarenal Clostridium septicum Aortitis with Rupture and Simultaneous Colon Cancer

We report a case of combined colon cancer and Clostridium septicum aortitis involving the suprarenal abdominal aorta with rupture. An 82-year-old male presented with fever, abdominal pain, and back pain associated with constipation. He was successfully treated by in situ aortic graft placement with polytetrafluroethylene and concomitant colon resection. Only 20 other cases of C. septicum mycotic aneurysm, aortitis, or aortic dissection have been reported. Concomitant surgical treatment for Clostridium aortitis or mycotic abdominal aortic aneurysm and colon cancer can be accomplished successfully in selected cases when the diagnosis of both conditions is made preoperatively.
