Inflammatory aortic aneurysm: report of a case suggesting athero-ischaemic aetiology.

: A case of inflammatory aortic aneurysm is presented in which histology revealed athero-emboli in the aortic vasa vasorum. It is suggested that ischaemic injury to the media, caused by lesions such as these and by other features of atherosclerosis, may be the initiating factor in some cases of idiopathic chronic periaortitis.
