Autoimmune & inflammatory nmd

Idiopathic inflammatory myopathies are a heterogenous group of diseases with prominent muscle inflammation and/or necrosis. Myositis is diagnosed through a combination of clinical, serologic, pathologic, and/or imaging findings, though these tools do not always yield clear diagnoses. A variety of neuromuscular conditions can mimic myositis, including muscular dystrophies, metabolic, endocrine, and toxic myopathies, and infectious myopathies. Through a series of four illustrative cases misdiagnosed as and treated for myositis, we highlight pitfalls and lessons to properly diagnosis myositis mimics to avoid immunosuppressants and potentially identify other reversible causes of myopathy.
