A case of brainstem infarction diagnosed with ophthalmic findings a day prior to radiopathological evidence

Although many brainstem infarctions are accompanied by dysarthria and sensory or motor nerve weakness in the face or limbs, some small and localized infarctions occasionally cause vague systemic symptoms or only ophthalmic manifestations. In the present report, we describe a patient diagnosed with a brainstem infarction using an ophthalmic examination within 8 hours of onset and a day before definite radiolpathological evidence.
