Viilonoduiar synovitis is an extremely rare condition of the synovial membrane in the dog. A 10‐yearoid, neutered crossbreed was presented with bilateral, progressive hindlimb lameness. Periarticuiar swelling was noted in both stifle joints. No craniocaudal instability was noted. Radiographs showed massive intra‐articular soft tissue proliferation in both joints, with no bony involvement. Arthrocentesls was unsuccessful. Exploratory arthrotomy of the left stifle revealed a greatly thickened, florid, proliferative synovial membrane. An Incisional biopsy was carried out and the histopathological diagnosis was chronic active viilonodular synovitis. A radical synovectomy was carried out in the right stifle joint 10 days later. Corticosteroid treatment was initiated 10 days after the second surgery and continued for six weeks, with a continuous clinical improvement. Eighteen months after discontinuation of the steroid therapy, the owners reported no recurrence of clinical signs although a mild stiffness was still present.
