“…However, no consensus has been reached for MRI findings. [5][6][7] Finally, regarding a question as to why the present case showed symptoms of hemiplegic migraine, we suppose that, in the present case, excitability in cortical lesions did not reach threshold of paroxysmal depolarization shift which evoked epileptic seizure, but reached threshold of cortical spreading depression (CSD) which evoked symptoms of migraine like a headache and aura. 8 To the best of our knowledge, MOG antibody testing for the differential diagnosis of hemiplegic migraine has not been performed in any other case reports.…”

Even though symptoms are important in the diagnosis of hemiplegic migraine, myelin oligodendrocyte glycoprotein antibody‐positive benign unilateral cortical encephalitis shows unique progress and findings on magnetic resonance imaging. We encountered a case of hemiplegic migraine showing cortical hyperintensity on magnetic resonance imaging, and positive results for myelin oligodendrocyte glycoprotein antibody. A certain proportion of patients diagnosed with hemiplegic migraine appear to show myelin oligodendrocyte glycoprotein antibody‐positive benign unilateral cortical encephalitis.
