A case of infected aortic aneurysm with possible intramural abscess resolved through discharge into the vascular lumen without surgical intervention.

Infected aortic aneurysms are difficult to treat and, in the absence of aortic resection, are almost always fatal. We report a case of an infected aortic aneurysm cured by antibiotic treatment alone. In this case, the intramural abscess was supposed to be naturally resolved by the discharge of pus into the vascular lumen and infection was suppressed by the antibiotic treatment.
