Isolated Fourth Nerve Palsy From Midbrain Hemorrhage: Case Report

Abstract

Isolated ocular motor palsies caused by brainstem strokes have been considered uncommon. However, since the development of magnetic resonance imaging (MRI), the occurrence of isolated ocular motor palsies resulting from brainstem strokes have become more frequently recognized (1–5). We report a patient who developed a fourth nerve palsy contralateral to a small dorsal mid-brain hemorrhage.
