Summary
Isolated accessory nerve lesions cause trapezius muscle weakness, often due to trauma or tumors. Diagnosis is confirmed by electromyography, but prognosis is poor despite various treatment options.
Area of Science:
- Neurology
- Neurosurgery
Background:
- Accessory nerve lesions can lead to significant functional deficits.
- Understanding the etiology and clinical presentation is crucial for patient management.
Observation:
- Three patients presented with isolated accessory nerve lesions.
- Clinical examination revealed paresis (weakness) of the trapezius muscle.
Findings:
- Electromyography can objectively substantiate trapezius muscle paresis.
- Common causes include trauma (surgical and non-surgical) and space-occupying lesions (tumors, abscesses).
- Idiopathic cases also occur, presenting diagnostic challenges.
Implications:
- The prognosis for accessory nerve lesions is generally poor.
- Treatment strategies are varied, including electrostimulation, NSAIDs, nerve transplantation, and muscle transposition, requiring individualized approaches.
