title: [Deep vein thrombosis in the differential diagnosis of knee-joint capsule changes in rheumatoid arthritis].
abstract: The authors describe 5 patients with rheumatoid arthritis; in 3 patients rupture of the synovial membrane and in 2 patients a calf cyst caused symptoms resembling a deep vein thrombosis. Contrast arthrography is of great help in differential diagnosis in conjunction with thorough anamnesis and clinical examination. The joint effusion plays a dominating role in the disease process, and treatment of the effusion is of the greatest importance for both prophylaxis and therapy of membrane rupture and calf cysts.
