title: [Nonatheromatous degenerative aneurysm of the popliteal artery in a young adult female].
abstract: A degenerative non atheromatous popliteal aneurysm was observed in a 32 year old woman. At microscopical examination of the aneurysmal shell, the internal elastic-lamina and the muscular fibers of the media appeared to be replaced by a thick acellular collagen layer. No other arterial abnormality was found on a complete arteriography and the etiological screening failed. Therefore the aneurysm was classified as an arterial dysplasia. As far as we know, only two similar cases were previously reported in the literature. The true nature of these lesions remain unknown.
