Summary

Pseudoathetosis is rarely linked to epidural lesions. This case highlights a migrated cervical disc as a treatable cause of pseudoathetosis and hand clumsiness.

Area of Science:

  • Neurology
  • Neurosurgery

Background:

  • Pseudoathetosis is a rare neurological sign.
  • Epidural lesions are an uncommon cause of pseudoathetosis.

Observation:

  • A 76-year-old woman presented with progressive hand clumsiness and athetotic movements.
  • Electrophysiological studies showed normal nerve conduction but delayed cortical somatosensory evoked potentials (SEPs).
  • Spinal MRI revealed a gadolinium-enhancing epidural mass at the C3-4 level.

Findings:

  • The epidural mass was identified as a migrated cervical disc.
  • Surgical removal of the migrated disc led to significant improvement in symptoms.

Implications:

  • This is the first reported case of pseudoathetosis caused by a migrated cervical disc.

  • Migrated cervical discs should be considered in the differential diagnosis of patients with profound sensory loss and pseudoathetosis.
  • Early diagnosis and surgical intervention can lead to favorable outcomes.
