Limb-girdle muscular dystrophy is a genetically heterogeneous group of disorders that are characterized by slowly progressing muscle weakness and presents a diagnostic problem in the neurological practice. The combination of clinical, radiological, and laboratory methods of examination plays an important role in referring the patient to genetic counseling and making the correct diagnosis. Magnetic resonance imaging of muscles is increasingly used to give clues in the primary muscle damage diagnosis, based on specific patterns of muscle lesion. The article provides two clinical cases as an example of an integrated approach to the diagnosis of progressive muscular dystrophy using genetic analysis and magnetic resonance imaging of muscles

Limb girdle muscular dystrophy type 2I (LGMD2I) is an autosomal recessive muscular dystrophy that is rare in Asia and is caused by mutations in the fukutin-related protein gene (FKRP). The aim of this study was to determine if there are any characteristic features of muscle on magnetic resonance imaging (MRI) in patients with LGMD2I harboring the founder mutation c.545A>G in FKRP. Using MRI, we delineated changes in the thigh muscles of ten patients with genetically confirmed LGMD2I. The majority of muscle biopsy specimens showed reduced glycosylation of α-dystroglycan, decreased expression of laminin α2, and a dystrophic pattern. In our cohort, the muscles with the most severe fatty infiltration were adductor magnus and vastus intermedius, whereas the rectus femoris, sartorius, and gracilis muscles were relatively spared. In seven patients, we identified a concentric fatty infiltration pattern that was most pronounced in the vastus intermedius and vastus medialis muscles around the distal femoral diaphysis. In this disease, the initial fatty infiltration of the posterior thigh muscles gradually progresses anteriorly regardless of the founder mutation in FKRP. Muscle tissue in patients with LGMD2I who have the founder mutation c.545A>G in FKRP shows a distinctive concentric pattern of fatty infiltration and edema on MRI.
