Summary
Parsonage-Turner syndrome, a brachial neuropathy, can be mimicked by giant cell arteritis affecting the brachial plexus. This case highlights clinical signs that suggest giant cell arteritis over typical Parsonage-Turner syndrome.
Area of Science:
- Neurology
- Vascular Neurology
- Rheumatology
Background:
- Parsonage-Turner syndrome is an idiopathic brachial neuropathy primarily affecting the C5 and C6 nerve roots.
- Giant cell arteritis (GCA) is a large-vessel vasculitis that can affect various arteries, including, rarely, the brachial plexus.
Observation:
- This report details a clinical case where symptoms initially suggested Parsonage-Turner syndrome.
- The patient presented with neurological deficits characteristic of brachial plexus involvement.
Findings:
- The clinical presentation mimicked Parsonage-Turner syndrome, prompting a differential diagnosis.
- Specific clinical signs were identified that pointed towards giant cell arteritis as the underlying cause.
Implications:
- Recognizing these specific clinical signs is crucial for differentiating GCA from Parsonage-Turner syndrome.
- Early diagnosis of GCA is vital to prevent complications such as stroke and vision loss.
- This case underscores the importance of considering systemic vasculitis in the differential diagnosis of brachial plexus neuropathies.
