There are several proposed theories of the natural etiology of intraosseous lipomas; however, all lack definitive support. Brought to you by the European Society of Radiology (ESR) -, AP X ray. The axial diffusion weighted image shows mixed signal intensity mass. A subchondral cyst is an intraosseous epiphyseal synovial fluid-filled void prevalent in osteoarthritis that may attain a diameter of 1-15 mm or more in size with the cyst’s longest axis usually along the coronal plane in the craniocaudal axis.
