Lymphatic filling during knee arthrography

Six cases of lymphatic filling during knee arthrography have been recorded in literature, all of which have had advanced rheumatoid arthritis. We report a case of lymph vessel filling from a popliteal cyst in a young male nonrheumatoid patient. It is concluded that abnormal synovial-lymphatic connection in the knee joint may occur also in other forms of synovial pathology and such a finding does not indicate rheumatoid inflammation.
