Dysferlinopathies, which are genetically characterised by mutations in the dysferlin gene lead to LGMD 2B, distal Miyoshi myopathies and a form of distal anterior compartment myopathy [42, 43]. On MRI, symptomatic patients with dysferlinopathies present with severe dystrophic changes in the anterior and posterior compartments of the thighs with a characteristic sparing of the gracilis and sartorius muscles. In the lower legs, dysferlinopathies predominantly affect the posterior compartment with a relative sparing of the medial head of the gastrocnemius muscle [44–46]. This distinct pattern is different from muscle involvement in LGMD2I and LGMD2A patients in which dystrophic changes in the posterior thigh and posterior calf muscle can frequently be observed [40].
