Brain lesions can mimic peripheral nerve damage. Seven patients showed sensory-motor deficits resembling ulnar or median nerve issues due to lacunar infarcts in the brain, not peripheral nerves.

Area of Science:

  • Neurology
  • Neuroscience

Background:

  • Peripheral nerve deficits are common clinical presentations.
  • Brain lesions causing peripheral nerve-like symptoms are rare.

Observation:

  • Seven patients presented with sensory-motor deficits mimicking peripheral nerve involvement.
  • Clinical and electrophysiological tests ruled out peripheral nerve damage.
  • Brain imaging revealed lacunar infarcts in the thalamus and corona radiata.

Findings:

  • Lacunar infarcts in the brain can manifest as peripheral nerve-like sensory-motor deficits.
  • Five patients exhibited ulnar nerve-like deficits, and two showed median nerve-like deficits.
  • No evidence of actual peripheral nerve disease was found in any patient.

Implications:

  • This presentation represents a novel lacunar syndrome.
  • Clinicians should consider brain lesions in patients with peripheral nerve deficit symptoms and normal nerve conduction studies.
  • Further research is needed to understand the mechanisms and prevalence of this condition.
