[An unusual dissecting cyst of the knee in a patient with rheumatoid arthritis].
An unusual synovial cyst of the knee in rheumatoid arthritis is reported. The communication with the knee joint anteriorly under the tibial insertion of the internal collateral ligament is in contrast with all the cases reported to date in the literature. The advantages of the air arthrogram (coupled with the arteriography) over the opaque contrast medium arthrography are shown to be superior for such special case.
