Axial fast spin-echo T1-weighted Whole-Body Muscle Magnetic Resonance Imaging (WBMRI) (A–D) showing severe fatty infiltration in the shoulder girdle muscles (A), moderate-severe fatty infiltration in quadriceps, gluteus and adductors muscles (B), moderate fatty infiltration in quadriceps muscle with relatively spared rectus femoris muscle compared to other quadriceps muscles (C) and severe fatty infiltration in the medial gastrocnemius muscle (D). Axial STIR WBMRI shows quadriceps muscle edema (E) and gastrocnemius muscle edema (F).
