Reversible cortical thickening in hemiplegic migraine

Case report of myelin oligodendrocyte glycoprotein antibody‐positive encephalitis mimicking hemiplegic migraine

“…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.…”

“…The diagnostic criteria for hemiplegic migraine place great weight on manifestations such as motor weakness, visual deficit, aesthesia, and aphasia. However, no consensus has been reached for MRI findings 5‐7 …”

Neuronal injuries evidenced by transient cortical magnetic resonance enhancement in hemiplegic migraine: A case report

“…So far, only a few reports have depicted MRI changes in hemiplegic migraine such as cortical thickening (1) and biphasic neurological changes with alternation of hypoperfusion and hyperperfusion (2). To our knowledge, one earlier case of familial hemiplegic migraine showed blood-brain barrier (BBB) breakdown, similarly to ours (3); however, the cortical enhancement appears much less demonstrative in this previous report.…”
