1. What is brachial plexitis?

Brachial plexus is formed by the anterior roots of cervical spinal nerves C5, C6, C7, C8 and T1 thoracic nerve. The brachial plexus plays an important role in controlling sensation and movement of the shoulders, arms, and hands.
Brachial plexitis is a form of neuromuscular atrophy caused by damage to the lower motor neurons of the plexus or some of its branches. This is a rare disease, mainly appearing in young people, characterized by unilateral shoulder pain and flaccid paralysis of the arm muscles. The illness usually lasts from a few days to a few weeks, but can also last for months.

To diagnose brachial plexitis, your doctor will consider your clinical symptoms, personal and family medical history. A number of paraclinical tools can be used for diagnosis such as:
Electromyography: is a diagnostic procedure that evaluates the health of muscles and the nerve cells that control them. Electromyography for patients with brachial neuralgia may show decreased range of motion and loss of nerve conduction. The picture is clearly visible 1-3 weeks after the symptoms of the disease appear. Magnetic resonance imaging (MRI), blood tests, biochemistry, immunology, cerebrospinal fluid, ... help support the differential diagnosis of brachial plexus inflammation and other diseases.
