Abstract/OtherAbstract:
In this case series and review of the literature, we describe 2 cases of abducens neuromyotonia (ANM) as the presenting sign of an intracranial tumor (meningioma). Review of the literature suggests that the pathophysiology of ocular neuromyotonia is incompletely understood. Most patients with ANM have a history of radiation therapy. The diagnosis of ANM is made on the basis of clinical findings and can be supported by electrophysiological studies. A complete neurologic examination is mandatory for patients with ANM. Treatment consists of eliminating the underlying cause; carbamazepine is effective in alleviating the symptoms of ANM. Neuroimaging should be performed if patients with ANM lack the typical history of radiation therapy, as ANM may be the presenting sign of an intracranial mass.
