XANTHOMATOUS INFILTRATION OF ANKLE TENDONS

We present a case of type II hyperbetalipoproteinemia in a patient who se diagnosis had been previously unrecognized, and who had previously been misdiagnosed with rheumatoid arthritis and later gout. Radiograph ic and MR imaging features of the patient's ankles were pronounced but otherwise typical of xanthomatous infiltration. Radiologic assessment can be useful in permitting a specific diagnosis to be made in patien ts with periarticular and tendinous swelling.
