Parsonage-Turner Syndrome synonyms

Parsonage-Turner Syndrome, also known as neuralgic amyotrophy, is a rare neurological condition characterized by sudden, severe shoulder pain followed by muscle weakness and atrophy. It is frequently referred to by several synonymous terms in medical literature, including idiopathic brachial neuritis and brachial plexus neuropathy, reflecting its complex historical classification and clinical presentation.

Why does Parsonage-Turner Syndrome have so many names?

The variety of names for Parsonage-Turner Syndrome stems from the medical community’s evolving understanding of the condition since it was first described in detail by Maurice Parsonage and Aldren Turner in 1948. Because the disorder affects the nerves of the brachial plexus—the network of nerves that sends signals from the spine to the shoulder, arm, and hand—early clinicians named it based on the anatomical location (brachial plexus neuropathy) or the clinical observation of rapid muscle wasting (neuralgic amyotrophy). The term "idiopathic" is often added to these names because the exact underlying cause of Parsonage-Turner Syndrome remains unknown in many cases, although it is widely believed to involve an immune-mediated response.

What are the common synonyms and historical terms used in medicine?

When reviewing medical records or searching for clinical literature, you may encounter several terms that describe the same underlying pathology. Understanding these synonyms is crucial for navigating health records and international databases. Common alternative names include:

• Neuralgic amyotrophy (the most common alternative)


• Idiopathic brachial neuritis


• Brachial plexus neuropathy


• Parsonage-Aldren-Turner syndrome


• Acute brachial radiculitis

How is the condition classified in official medical systems?

Official medical classification systems provide standardized codes to help track the condition globally. In the International Classification of Diseases (ICD-10), it is often categorized under G54.0 (Brachial plexus disorders). Orphanet, the reference portal for rare diseases, lists Parsonage-Turner Syndrome under the identifier ORPHA:869. While OMIM (Online Mendelian Inheritance in Man) focuses primarily on genetic conditions, it occasionally references the syndrome in the context of hereditary neuralgic amyotrophy, a distinct but related genetic variant. Currently, Parsonage-Turner Syndrome remains the most widely recognized and preferred clinical name used by neurologists and rheumatologists worldwide.

Is the terminology consistent across different countries?

While Parsonage-Turner Syndrome is the standard term in English-speaking medical literature, regional variations persist. In some European medical traditions, the term "neuralgic amyotrophy" is preferred because it describes the clinical reality of the nerve pain followed by muscle atrophy without implying a specific anatomical restriction to the brachial plexus. Regardless of the regional naming convention, the diagnostic criteria remain consistent, focusing on the acute onset of pain followed by a period of weakness and gradual recovery.

Next steps

• Consult a neurologist or a physical medicine and rehabilitation (physiatrist) specialist to confirm your diagnosis.


• Connect with the 160 members of the Parsonage-Turner Syndrome community on DiseaseMaps.org to share experiences and coping strategies.


• Request copies of your medical records and ensure your physician is aware of the various synonyms if you are seeking a second opinion.


• Keep a symptom log, noting the timing of pain onset and any subsequent physical limitations, to share with your care team.
