title: The radiological appearance of atherosclerotic popliteal artery aneurysms: the "dog-leg" sign.
abstract: The radiological appearance of popliteal aneurysms is described. Althought the lumen of the artery is often of normal diameter there is elongation of the vessel which frequently results in an acute "dog-leg". This sign has not been previously described.
