A Rare Midbrain Syndrome with Bilateral Cerebellar Ataxia and Isolated Superior Rectus Palsy: Wernekinck Commissure Syndrome

Abstract

Wernekinck commissure syndrome is a rare midbrain syndrome, usually resulting in selective destruction of the decussation of the superior cerebellar peduncle. This syndrome can present with symptoms such as bilateral cerebellar ataxia, ophthalmoplegia, and palatal tremor. Here, we report a 61-year-old female with acute onset of bilateral cerebellar ataxia and isolated superior rectus palsy diagnosed on Wernekinck commissure syndrome confirmed by magnetic resonance imaging.
