Lymphatic Visualization During Contrast Arthrography of the Knee

Abstract

Opacification of the pariarticular lymphatic channels has been observed as an incidental finding during contrast arthrography in cases of chronic rheumatoid arthritis of the knee. Apparently, the radiographic appearance is due to the hyperplastic response of the lymphatic system to chronic rheumatoid arthritis and to an associated increase in synovial permeability.
