Isolated facial myokymia and facial contracture: computed tomography and magnetic resonance imaging correlation.
Isolated facial myokymia with contracture can be the earliest manifestation of intrinsic lesions of the brainstem. We report a case of facial myokymia with contracture occurring as the result of a pontine glioma, as depicted on cranial computed tomography and magnetic resonance imaging studies. The rostral location of the tumor supports the supranuclear disinhibition hypothesis of facial myokymia.
