Lipoma arborescens is a rare disorder which is characterised by villous, polypoidal lipomatous proliferation of the synovial tissues [1]. It usually involves the suprapatellar pouch [2]. The exact etiology of lipoma arborescens is unknown. It is a benign, indolent, intraarticular lesion that commonly affects the knees, although other sites such as shoulder, elbow, wrist and ankle have been described before [3]. The disease normally affects one knee and bilateral knee involvement is a very rare occurrence [4]. We report a case of bilateral knee lipoma arborescens in an elderly lady in our centre.
