title: Uncommon Diseases of The Popliteal Artery: A Pictorial Review.
abstract: Uncommon diseases of the popliteal artery include cystic adventitial disease, popliteal artery entrapment syndrome (PAES) and popliteal artery aneurysm (PAA). Because all of these conditions may present with pain or intermittent claudication, imaging is crucial for differentiating them and directing management. Delayed diagnosis can lead to major complications, including acute limb ischemia. Our aim is to provide an illustrative overview of these conditions in order to make radiologists aware of them and avoid misdiagnosis for timely appropriate management. Teaching Points • Cystic adventitial disease diagnosis is based on evidence of cysts within artery walls. • A variety of anatomic variations may result in PAES. • PAES may be bilateral. • PAA is most commonly encountered in men. • Acute complications of PAA include acute thrombosis and distal embolization.
