Idiopathic Inflammatory Myopathies

A. Clinical Features
  • Robert L. WortmannJr.


  • Idiopathic inflammatory myopathies (IIM) is a heterogeneous group of disorders characterized by chronic inflammation of striated muscle and skin.

  • Painless proximal muscle weakness with or without rash is the hallmark feature.

  • ■ Increased serum muscle enzymes, muscle biopsy, electromyography (EMG), and magnetic resonance imaging (MRI) can assist in the diagnosis.
