[Personage-Turner syndrome--case report].

Area of Science:

• Neurology
• Immunology

Background:

• Parsonage-Turner syndrome, also known as acute brachial radiculitis, is a rare neurological disorder.
• It typically presents with severe shoulder pain and subsequent muscle weakness and atrophy in the affected arm.
• The exact etiology remains unknown, but an autoimmune-inflammatory mechanism is suspected.

Observation:

• The diagnosis is primarily clinical, based on characteristic symptoms and by excluding other conditions affecting the brachial plexus.
• In this case, initial investigations suggested discopathy as a potential cause for the observed paresis.
• However, a subsequent re-evaluation led to a change in the diagnosis.

Findings:

• The presented case highlights the diagnostic challenges in Parsonage-Turner syndrome.
• Differential diagnosis is crucial, as initial findings can be misleading.
• The importance of reassessment in diagnosing rare neurological conditions is emphasized.

Implications:

• Accurate diagnosis of Parsonage-Turner syndrome is essential for appropriate patient management.
• Understanding the potential for misdiagnosis underscores the need for thorough clinical evaluation.
• Further research into the autoimmune basis of this syndrome may improve diagnostic accuracy and treatment strategies.
