A 67-year-old male with a medical history of hypertension, diabetes mellitus, and previous ischemic stroke applied to the neurology outpatient clinic due to acute onset double vision which had abruptly started 2 days ago. On neurological examination, the right eye could not adduct whereas nystagmus occurs on the left eye abduction (Figure 1). Upon history interrogation, it was learned that the patient had applied to the emergency department two days ago and cranial diffusion-weighted imaging (DWI) was performed which resulted in normal ranges (Figure 2).
