Abstract

Popliteal cystic adventitial disease is a rare arterial condition characterised by mucinous cyst formation in the adventitia of the popliteal artery producing stenosis or occlusion of the arterial lumen. It predominantly affects males and typically presents in the thirties with disabling intermittent calf claudication. Because of the demographic it affects it is of relevance to military medical practitioners. We present such a case and describe the presentation, clinical features, differential diagnoses and imaging findings as well as the theories surrounding pathogenesis, clinical management and surgical treatment options.
