title: A Case of Asymptomatic Inclusion Body Myositis.
abstract: OBJECTIVE
  To present a case of asymptomatic inclusion body myositis.
  
  
  METHODS
  The authors report a case of a 67-year-old man who presented with idiopathic hyperCKemia. Physical examination including a complete neurological evaluation was unremarkable. Systemic causes of hyperCKemia, including medication side effects, metabolic and endocrine disorders, and connective tissue disorders, were ruled out with various indicated tests.
  
  
  RESULTS
  Two and a half years after initial consultation, the patient reported left knee pain. Magnetic resonance imaging of the left knee showed edema in the mid and distal aspect of the vastus medialis and vastus lateralis muscles. A biopsy of the left quadriceps muscles was diagnostic of inclusion body myositis. He remained asymptomatic for the ensuing 2.5 years.
  
  
  CONCLUSIONS
  Asymptomatic hyperCKemia should be investigated and followed closely for definitive diagnosis and possible treatable causes.
