Facio-scapulo-humeral muscular dystrophy
Facio-scapulo-humeral muscular dystrophy (FSHD) is the third most common muscular dystrophy (worldwide prevalence 1:20,000) [52]. FSHD is characterised by asymmetric loss of strength and atrophy of muscular tissue starting in the face and shoulder region [56]. These typical clinical findings are also mirrored on muscle imaging, which shows marked asymmetry and involvement of the medial gastrocnemius, the tibial anterior and the soleus muscles in the lower legs. At the thigh, the most frequently involved muscles are the semimembranosus, followed by the biceps femoris, the semitendinosus muscle and the adductor group muscles [57, 58].
