Association of Limb-Girdle muscular dystrophy with multiple sclerosis: A case report.

Background: The association of limb-girdle muscular dystrophy (LGMD) with other neurological disorders is uncommon.

Methods: We report a 25-year-old female with LGMD who suffered from slowly progressive proximal muscular weakness and atrophy since she was 12 years of age. The patient recently presented with acute loss of left side visual acuity. After evaluation, findings were suggestive of multiple sclerosis.

Conclusions: This is the first report of LGMD in association with MS. The simultaneous occurrence of MS with myopathies may be incidental but there may be a genetic susceptibility for both diseases. This comorbidity may influence the treatment of MS.
