Overview
Acute brachial neuritis (also known as Parsonage-Turner syndrome) is a rare syndrome of unknown etiology affecting mainly the lower motor neurons of the brachial plexus and/or individual nerves or nerve branches. Acute brachial neuritis usually is characterized by the acute onset of excruciating unilateral shoulder pain, followed by flaccid paralysis of shoulder and parascapular muscles after several days.
Causes
Acute brachial neuritis is a form of peripheral neuropathy. It occurs when there is damage to the brachial plexus, an area where a nerve bundle from the spinal cord splits into the individual arm nerves.
Epidemiology and Demographics
In the USA each year, there are approximately 1 to 2 cases per 100,000 people. The reported incidence in the UK is 3 cases per 100,000 people.
Natural History, Complications and Prognosis
The likely outcome depends on the cause. A good recovery is possible if the cause is identified and properly treatment. In some cases, there may be a partial or complete loss of movement or sensation. Nerve pain may be severe and may persist for a long time.
Treatment
Surgery
Some patients with brachial plexopathy may benefit from surgery if nerve compression is the cause of the symptoms.
