Inflammatory Myositis - How to prevent?

Inflammatory Myositis - Diagnosis

​Due to the many different forms of inflammatory myositis and similarities to other muscular and nerve diseases, it may take a few visits to the doctor before the condition can be diagnosed. After a careful physical examination, the doctor will order other tests to confirm the diagnosis. Such tests may include:

  • Routine tests like a full blood count, Erythrocyte Sedimentation Rate (ESR) and C-reactive protein (CRP).

  • Blood tests for muscle enzymes and auto-antibodies.  Muscle enzyme levels (usually raised initially) are useful for monitoring progress and response to treatment.  

Other Investigations:

  • Electromyogram (EMG)
    This is a test that measures the electrical activity of muscles. In patients with inflammatory myositis the EMG would be abnormal.

  • Muscle Biopsy
    The doctor takes a sample of the affected muscle to be examined under the microscope. The procedure is done under local anaesthesia.

  • X-ray of the chest
    To investigate for lung cancer and lung involvement associated with inflammatory myositis.

  • Magnetic Resonance Imaging (MRI)
    This painless scan can identify abnormal muscles and can be used to locate the best site for a biopsy and to monitor the progress of the disorder.

  • A chest and abdominal CT scan
    This test is useful to investigate for hidden cancers.

  • Gastroscopy and colonoscopy
    These tests are useful to investigate for underlying cancers in the gastrointestinal tract.
