Abstract
We report a case of sudden-onset abducens nerve palsy in a 15-year-old boy with ecchordosis physaliphora, a benign retroclival remnant that is usually asymptomatic. Most reported symptomatic cases have been treated with resection via craniotomy or endoscopic resection. Our patient recovered after a short course of oral corticosteroids, but the abducens nerve palsy recurred 6 months later
