title: Clinically occult isolated right iliac mycotic aneurysm with duodenal involvement in a diabetic elderly man: multislice CT diagnosis.
abstract: A diabetic old man presented with vague abdominal discomfort and intermittent tarry stools for 2 days and gastric ulcers with bleeding was diagnosed after endoscopy. Multislice computed tomography (MSCT) clearly depicted an isolated right iliac mycotic aneurysm with retroperitoneal extension and duodenal involvement. Timely operation and effective antibiotic treatment resulted in complete recovery. To our knowledge, this is the first report of an isolated mycotic iliac artery aneurysm (IAA) complicated with an aneurysmo-duodenal fistula induced by Klebsiella pneumoniae.
