Abstract Introduction Mycotic aneurysms account for a small proportion of all aneurysms. Escherichia coli a gram-negative organism is recognised as a rare cause of aortic aneurysm. We report two cases of mycotic aneurysm caused by the same strain of multi-resistant Escherichia coli. The purpose of this case report is to highlight the possibility that this strain may be associated with an increased risk of endovascular infection especially in extra-aortic sites. These aneurysms can be difficult to detect and can have serious consequences. Case presentation In case one the patient presented with symptoms and signs of .
