title: Pseudoperipheral palsy: a case of subcortical infarction imitating peripheral neuropathy.
abstract: BACKGROUND
  Vascular damage in the central hand knob area can mimic peripheral motor nerve deficits.
  
  
  METHODS
  We describe the case of a woman presenting with apparent peripheral neuropathy. Brain magnetic resonance imaging and computed tomography angiography revealed an infarct in the precentral hand knob area, with significant stenosis in the right proximal middle cerebral artery trunk. Subsequent 3-Tesla magnetic resonance imaging of the brain suggested cerebral angiitis. The patient experienced improved hand function following combined glucocorticoid and cyclophosphamide treatment.
  
  
  CONCLUSIONS
  Vascular damage in the hand knob area should be considered when evaluating peripheral motor nerve deficits in the presence of normal nerve conduction velocities. The diagnosis of cerebral angiitis remains a major challenge for clinicians.
