Neuritis Plexus brachialis
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)

atypical Parsonage-Turner syndrome: a case report. Presentation of patient’s neuropathic symptoms as captured by the neurological physical examination. In light grey: T1 dermatome. In dark grey: T2 dermatome. In blue: areas characterized by dysesthesia. In red: areas characterized by both dysesthesia and mild hypoesthesia.

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
- Charcot-Marie-Tooth disease
- Dejerine-Sottas disease
- chronic inflammatory demyelinating polyneuropathy (a chronic form of Guillian-Barré syndrome)
- hereditary neuralgic amyotrophy (familial BPL neuropathy)
- idiopathic brachial plexitis
