Acute weakness in both arms may signal an incomplete anterior spinal artery (ASA) syndrome. This condition, affecting the anterior horns, can be diagnosed with MRI and electrophysiology.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Spinal Cord Medicine

Background:

  • Pure motor bilateral arm paresis of acute onset is a rare clinical presentation.
  • This syndrome is infrequently described and often linked to ischemia within the anterior spinal artery (ASA) territory.

Observation:

  • Two patients presenting with acute onset of pure motor deficits affecting both upper extremities were studied.
  • Clinical presentation included significant weakness in both arms without other neurological impairments.

Findings:

  • Cervical spinal cord magnetic resonance imaging (MRI) identified infarcts consistent with the ASA territory in both patients.
  • Electrophysiological studies in one patient indicated subtle involvement of the gray matter.

Implications:

  • The findings suggest that an incomplete ASA syndrome, particularly affecting the anterior horns, should be considered in cases of acute bilateral arm weakness.
  • MRI and electrophysiology are crucial diagnostic tools for confirming the location and extent of spinal cord lesions in this syndrome.
