Answer

Muscle disorders

  • Focal myositis [44]

    • This disorder may present with focal or asymmetric weakness and wasting.

    • The myopathy may progress or remain stable.

    • Serum creatine phosphokinase (CPK) may be elevated, and EMG shows brief, small-amplitude, motor unit potentials and fibrillations in the affected muscles.

    • Immunosuppressive therapy may arrest progression.
