ABSTRACT
Background: Although internuclear ophthalmoplegia (INO) is a definite sign of an intrapontine or mesencephalic lesion, INO is rarely associated with rotatory nystagmus in pontine lesions. We experienced a case of INO with transient rotatory nystagmus in facial colliculus infarction. Case Report: An 83-year-old male patient was admitted for acute vertical diplopia. Neurological examination revealed bilateral INO with transient ipsiversive rotatory nystagmus and ipsilateral peripheral type facial palsy. Diffusion weighted image revealed focal infarction in the right facial colliculus. Ocular symptoms were improved within one month. Conclusions: We report a case of bilateral INO with transient rotatory nystagmus in right facial colliculus infarction.
