Extensive Postradiation Ocular and Diffuse Cranial Neuromyotonia Mimicking Myasthenia Gravis

摘要

Background:Ocular neuromyotonia is a rare, but well-recognized, complication of cranial irradiation.Case Report: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.
