A moderate hypotrophy of quadriceps and leg muscles as well as winging scapula were detected (Figure 1).
Muscle MRI axial T1-weighted images at the level of the shoulder girdle (a), lumbar muscles (b), and pelvic girdle (c), showing minimal adipose involvement of the deltoid muscles (a, arrow), discrete fatty substitution at the level of the abdominal and lumbar muscles (b), while gluteus maximus and medium are completely substituted (c).

Shoulder girdle muscles showed minimal adipose involvement of the deltoid muscles, while face, abdominal, and lumbar muscles were spared (Figures 2, 3).
Muscle MRI axial T1 (a,b) and T2 STIR images (c,d) of the lower limbs shows mainly complete fatty substitution of both anterior and posterior thigh muscles, with selective sparing of the medial ones, specifically rectus, gracilis, sartorius, and adductor magnus (a). Diffuse adipose involvement also of the leg muscles, less pronounced at the level of the soleus, and tibialis anterior muscles (b). Inhomogeneous STIR hyperintensity was also associated, mainly in the quadriceps at the level of the thigh and in the tibialis anterior at the level of the leg (c,d).
