title: Extensive Postradiation Ocular and Diffuse Cranial Neuromyotonia Mimicking Myasthenia Gravis.
abstract: BACKGROUND
  Ocular neuromyotonia is a rare, but well-recognized, complication of cranial irradiation.
  
  
  METHODS
  Using figures and videos, we report a 52-year-old man with extensive ocular, brainstem, and lower cranial nerve neuromyotonia postradiation therapy for a fourth ventricle glioma who, in the context of an apparently positive edrophonium test, was initially misdiagnosed with myasthenia gravis.
  
  
  CONCLUSIONS
  This is the first case of postirradiation neuromyotonia to be reported with such extensive cranial nerve and brainstem involvement.
