Summary
A rare venous aneurysm in the upper arm compressed the median nerve, causing pain and dysfunction. Diagnosis via sonography and surgical removal of the aneurysm provided complete pain relief.
Area of Science:
- Vascular Surgery
- Neurology
- Diagnostic Imaging
Background:
- Peripheral nerve compression syndromes can arise from various etiologies.
- Median nerve entrapment typically occurs at the wrist or elbow.
- Vascular malformations are uncommon causes of nerve compression.
Observation:
- A spontaneous venous aneurysm in the upper arm presented as a cause of median nerve dysfunction.
- Initial surgical interventions targeting the nerve itself were unsuccessful.
- Clinical examination and sonography were crucial for accurate diagnosis.
Findings:
- Sonography correctly identified the venous aneurysm as the source of nerve entrapment.
- Surgical resection of the venous aneurysm led to complete resolution of symptoms.
- This represents the first documented case of a venous malformation in the upper arm causing focal neuropathy.
Implications:
- Highlights the importance of considering vascular anomalies in the differential diagnosis of peripheral neuropathies.
- Demonstrates the diagnostic utility of sonography in localizing nerve compression.
- Suggests surgical excision of venous aneurysms as an effective treatment for associated neuropathic pain.
