[Full popliteal fossa].

Many reasons of clinical discussions about a filling of the popliteal fossa arise from this special anatomical area which is encumbered, so often requested by the activity of joints and muscles and so, since the embryological development. Although rare, perhaps because unrecognised, ischemic disorders, venous signs, swollen legs, permanent or intermittent full fossa . . . are the more frequent clinical aspects. The main patterns are arterial, rarely venous and more rarely arteriovenous aneurysms, adventitial cystic disease, lipoma, synovial or sebaceous cyst . . . malignant tumours, exostosis . . . Serious examination, functional techniques of which Doppler, angiographies . . . So, quite a lot of diagnostic discussions, even during surgical interventions.
