Femoral vein compression by a cyst is a rare feature. The most frequent aetiology is a synovial cyst of the hip joint. Adventitial cyst of the femoral vein is a much more infrequent cause. Morphological examination (Doppler US, CT scan or MRI) can easily recognise the cystic nature of the lesion but differentiation between these two causes can be difficult to make. In case of a synovial cyst, a plane of dissection can be found between the cyst and the femoral vein. This plane does not exist in case of adventitial cyst. The histological examination is identical because both cyst formations have the same tissue origin. We report four cases of femoral vein compression caused by a cystic lesions treated at our institution.
