Baker’s cyst

Summary

Background: Acute swelling of the leg requires rapid exclusion of a deep vein thrombosis; ideally by duplex ultrasonography.

Case report: 51 year old patient with a painful swollen calf after physical exercises. After a thrombosis had been ruled out by compression ultrasonography an anechoic space-occupying lesion was seen in the popliteal fossa (Baker’s cyst) with small tears in the capsule at the distal end. This was where the cyst had ruptured and the contents had emptied into the muscle layers in the calf, thus causing the swelling and the pain.
