Superior Oblique Myokymia Associated with a Dural Arteriovenous Fistula

Abstract

Superior oblique myokymia (SOM) is an uncommon ocular motility disorder characterized by intermittent uniocular vertical or torsional oscillations with periodic remissions and exacerbations. Although generally idiopathic in origin, isolated case reports have documented its association with intracranial pathology. We present a case of superior oblique myokymia associated with a dural arteriovenous fistula.
