Article title

Bilateral lipoma arborescens of the knee: a case report


Title variants

Languages of publication



Lipoma arborescens, a diffuse articular lipomatosis, is a rare disorder characterized by marked villiform synovial proliferation and diffuse replacement of the subsynovial tissue by mature adipocytes. Unilateral joint involvement is the usual presentation while bilateral joint involvement is more uncommon. We reported a case of bilateral lipoma arborescens in a male patient with associated marked patellofemoral osteoarthritis and described the MR imaging findings.
