Parsonage–Turner syndrome

Parsonage–Turner syndrome is also known as acute brachial neuropathy and acute brachial radiculitis. Other names used are Parsonage–Aldren–Turner syndrome, neuralgic amyotrophy, brachial neuritis, brachial plexus neuropathy, or brachial plexitis.

The syndrome is idiopathic; although many specific risk factors have been identified (such as; post-operatively, post-infectious, post-traumatic or post-vaccination) the aetiology is still unknown. The condition manifests as a rare set of symptoms most likely resulting from autoimmune inflammation of unknown etiology of the brachial plexus. (The brachial plexus is a complex network of nerves through which impulses reach the arms, shoulders and chest.)
