Acute sensory neuronopathy: identified with electrodiagnosis and magnetic resonance imaging.
We report on a 13-year-old female with idiopathic acute sensory neuronopathy mimicking a sensory form of Guillain-Barré syndrome, which was identified by using electrodiagnosis and spine magnetic resonance imaging. Motor conduction results were normal, but no sensory nerve action potentials were seen in the four limbs. On magnetic resonance imaging of the whole spine, the diffuse gadolinium enhancement of the dorsal roots in the spinal canal was detected, without evidence of intramedullary lesions. The clinical symptoms and electrodiagnostic findings had persisted for more than 18 months of follow-up.
