AP (a) and lateral (b) radiographic imaging of distal femur demonstrates aberrant calcification of the suprapatellar region within the soft tissue. Transverse (c) and lateral magnetic resonance imaging (d) reveals that the calcified mass is confined to the subcutaneous tissue with no connections to the underlying bone.
