[edit] Discussion of Parsonage-Turner syndrome

  • Parsonage-Turner syndrome (PTS) is also known as acute brachial neuritis and neuralgic amyotrophy
  • Uncommon—but not rare—clinical problem.
  • Although this abnormality typically has a characteristic manifestation, namely acute onset of severe shoulder pain followed shortly thereafter by weakness of at least one shoulder muscle, it is often confused clinically with more well-known disorders such as cervical spondylolysis, rotator cuff tear, shoulder impingement syndrome, and acute calcific tendonitis.
  • Failure to consider PTS may result in inappropriate treatment or even unnecessary surgery.

[edit] Imaging Findings for Parsonage-Turner syndrome

[edit] MRI

  • Most typical of PTS is that of diffuse high signal intensity involving one or more muscles innervated by the brachial plexus depicted on T2-weighted images.
  • T1-weighted MR images also may show atrophy of the affected muscle(s).
  • The pattern of muscular involvement should match the distribution(s) of one or more peripheral nerves originating from the brachial plexus.
