A case of unilateral lower limb swelling secondary to a ganglion cyst
1University Hospital Lewisham, Lewisham High Street, London, UK.
Introduction:
We present a case of leg swelling of unusual aetiology which serves as a reminder to the surgeon to consider causes of leg swelling other than lymphoedema and venous insufficiency.
Case Report:
A 40 year old man developed progressive left leg swelling despite treatment of his varicose veins. Subsequent investigation revealed a lesion compressing the femoral vein. At exploration this was found to be a ganglion cyst. Removal of this resulted in resolution of the swelling.
Discussion:
Venous compression due to external cystic lesions, although rare, is recognised. This case serves as a reminder that the rarer causes of limb swelling should not be forgotten, especially where potentially treatable.
