Anti-HMGCR myopathy mimicking facioscapulohumeral muscular dystrophy

Abstract

Statin use can lead to various muscle-related issues, including benign creatine kinase (CK) elevations, myalgias, toxic myopathies, rhabdomyolysis, and immune-mediated necrotizing myositis (IMNM), which primarily affects older males. IMNM presents with proximal muscle weakness, elevated CK levels, and specific antibodies.
