title: Xanthomatous infiltration of ankle tendons.
abstract: We present a case of type II hyperbetalipoproteinemia in a patient whose diagnosis had been previously unrecognized, and who had previously been misdiagnosed with rheumatoid arthritis and later gout. Radiographic 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 patients with periarticular and tendinous swelling.
