- Uncommon with 1.64 cases per 100,000 population in the US
- Simulates disc disease
- Male preponderance with 20 to 60 years age
- Severe pain followed by weakness is hall mark
- 15% follow immunization
- Viral etiology is postulated
- Other causes are drugs, idiopathic, radiation etc.
- MRI shows extensive edema along the nerve branches along with corresponding muscle edemata, leading to atrophy on the followup scans
- Electromyography suggest fibrillation potentials and positive waves
- Nerve conduction suggest denervation
