Acute brachial neuritis

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1] Associate Editor(s)-in-Chief:

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.

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.

• [Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as:

• [Differential dx1]
• [Differential dx2]

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.

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.

• Common risk factors in the development of [disease name] are [risk factor 1], [risk factor 2], [risk factor 3], and [risk factor 4].

• The majority of patients with [disease name] remain asymptomatic for [duration/years].
• Early clinical features include [manifestation 1], [manifestation 2], and [manifestation 3].
• If left untreated, [#%] of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
• Common complications of [disease name] include [complication 1], [complication 2], and [complication 3].
• Prognosis is generally [excellent/good/poor], and the [1/5/10­year mortality/survival rate] of patients with [disease name] is approximately [#%].

• The diagnosis of [disease name] is made when at least [number] of the following [number] diagnostic criteria are met:

• [criterion 1]
• [criterion 2]
• [criterion 3]
• [criterion 4]

• [Disease name] is usually asymptomatic.
• Symptoms of [disease name] may include the following:

• [symptom 1]
• [symptom 2]
• [symptom 3]
• [symptom 4]
• [symptom 5]
• [symptom 6]

• Patients with [disease name] usually appear [general appearance].
• Physical examination may be remarkable for:

• [finding 1]
• [finding 2]
• [finding 3]
• [finding 4]
• [finding 5]
• [finding 6]

• There are no specific laboratory findings associated with [disease name].

• A [positive/negative] [test name] is diagnostic of [disease name].
• An [elevated/reduced] concentration of [serum/blood/urinary/CSF/other] [lab test] is diagnostic of [disease name].
• Other laboratory findings consistent with the diagnosis of [disease name] include [abnormal test 1], [abnormal test 2], and [abnormal test 3].

• There are no [imaging study] findings associated with [disease name].

• [Imaging study 1] is the imaging modality of choice for [disease name].
• On [imaging study 1], [disease name] is characterized by [finding 1], [finding 2], and [finding 3].
• [Imaging study 2] may demonstrate [finding 1], [finding 2], and [finding 3].

• [Disease name] may also be diagnosed using [diagnostic study name].
• Findings on [diagnostic study name] include [finding 1], [finding 2], and [finding 3].

Some patients with brachial plexopathy may benefit from surgery if nerve compression is the cause of the symptoms.

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.

Damage to the brachial plexus is usually related to direct injury to the nerve, stretching injuries (including birth trauma), pressure from tumors in the area, or damage that results from radiation therapy.

Acute brachial neuritis may also be associated with:

• Birth defects (that put pressure on the neck area).
• Exposure to toxins, chemicals, or drugs.
• Inflammatory conditions, such as those due to a virus or immune system problem.
• In some cases, it is idiopathic.

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.

Young to middle-aged adults are most commonly affected, although the condition can occur at any age .

Males are 2 to 4 times more likely to have this medical condition than females. Though there are exceptions when compared with the inherited form, which affects males and females equally.

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.

• Deformity of the hand or arm, mild to severe, which can lead to contractures
• Partial or complete arm paralysis
• Partial or complete loss of sensation in the arm, hand, or fingers
• Recurrent or unnoticed injury to the hand or arm due to diminished sensation

The likely outcome depends on the cause. A good recovery is possible if the cause is identified and properly treatment.
