Axial-T1-weighted magnetic resonance images of the muscles showing a typical pattern of muscle involvement. The hyperintense areas reflect fatty infiltration. (A) In the thigh, the long and short head of the biceps femoris (BL-L, BL-S), semimembranosus (SM), semitendinosus (ST), adductor magnus (AM), and gracilis (GR) show moderate fatty infiltration. (B) In the lower leg, the tibialis anterior (TA), extensor digitorum longus (EDL), peroneus longus (PL) show conspicuous fatty changes (red arrows).
