brachial plexitis

Imaging in
Lyme neuroborreliosis. Brachial plexus neuritis in a 74-year-old woman with acute distal right arm paresis. In the preceding weeks she had nausea, vomiting and weight loss, and felt increasingly forgetful and unsteady. A fluid-sensitive coronal STIR sequence showed diffusely increased signal of the nerve bundle on the right side (arrows) compared to the left side. Lumbar puncture followed, and showed cell count of 101/mm3 as well as a positive Bb IgG antibody index (AI)

Brachial plexitis refers to inflammatory change involving the brachial plexus. This is in contrast to a brachial plexopathy meaning any form of pathology involving the brachial plexus.

Epidemiology

Brachial plexitis is more commonly seen in men between 30 and 70 years of age and is bilateral in 10-30% of patients .

Pathology

Etiology
  • post radiation plexitis: usually presents 5-30 months after treatment, generally with doses of ≥6000 cGy
  • viral brachial plexitis, e.g. cytomegalovirus, Coxsackie, herpes zoster, Epstein-Barr virus, parvovirus B19
  • immune-mediated
  • toxic (related to previous serum, vaccine, antibiotic or other drug administration, human immunodeficiency virus serology)
  • recent surgery
  • anesthesia
  • Lyme disease
  • heredofamilial hypertrophic neuropathies
  • hereditary neuralgic amyotrophy (familial BPL neuropathy) 
  • idiopathic brachial plexitis
