Reversible Lesion of the Corpus Callosum in a Patient With Migraine With Aura: A Case Study

Objective To describe a patient with migraine with aura (MWA) who was found to have a reversible lesion of the corpus callosum. Background Reversible lesions of the splenium of the corpus callosum are well‐described clinical‐radiographic phenomena, which have been associated with a wide array of disease states, including epilepsy, demyelinating disease, infection, and metabolic derangements. There have been few case reports in the literature to date of these lesions associated with migraine headache. Design/Methods A case report. Results A 41 year‐old female with a history of migraine with visual aura presented with headache associated with left‐sided sensorimotor deficits. Routine laboratory tests were within normal limits. An electroencephlogram was also normal. Magnetic resonance imaging (MRI) of the brain with and without contrast revealed areas of restricted diffusion in the splenium and the genu of the corpus callosum. The patient's symptoms resolved after 2 days. A follow‐up MRI 2 days after the onset of symptoms revealed resolution of the callosal lesions. The patient was diagnosed clinically with migraine with prolonged aura. Conclusion MWA may be associated with reversible lesions of the corpus callosum.
