Brachial plexopathy with Sjögren syndrome

Area of Science:

• Neurology
• Rheumatology
• Immunology

Background:

• Sjögren's syndrome is a systemic autoimmune disease primarily affecting exocrine glands.
• Neurological involvement in Sjögren's syndrome is common but typically occurs after the onset of classic symptoms.
• Brachial plexopathy is a rare neurological complication of autoimmune disorders.

Observation:

• This report details an unusual case of brachial plexopathy.
• The patient presented with neurological symptoms preceding other characteristic manifestations of Sjögren's syndrome.
• This presentation underscores the diverse clinical spectrum of Sjögren's syndrome.

Findings:

• The brachial plexopathy was directly associated with the manifestation of Sjögren's syndrome.
• This case demonstrates that Sjögren's syndrome can present initially with isolated neurological involvement.
• Early recognition of neurological signs is crucial for timely diagnosis.

Implications:

• Clinicians should consider Sjögren's syndrome in the differential diagnosis of brachial plexopathy, even in the absence of sicca symptoms.
• This case expands the understanding of Sjögren's syndrome's initial presentations.
• Prompt diagnosis and management of Sjögren's syndrome can prevent further neurological damage and systemic complications.
