Neuronal injuries evidenced by transient cortical magnetic resonance enhancement in hemiplegic migraine: A case report
Abstract
Background Magnetic resonance imaging abnormalities in hemiplegic migraine have been described previously but were limited to a cortical thickening and biphasic alternation of hypoperfusion and hyperperfusion. Our report reveals possible blood-brain barrier disruption during migraine. Case We present the first demonstrated case of regressive diffuse hemispheric cortical enhancement in sporadic hemiplegic migraine, with histological correlation revealing neuronal lesions similar to ischemic lesions. This is probably due to the severity of the attack as indicated by the left hemiplegia and transient altered consciousness in our 43-year-old male patient. Conclusion Cortical contrast enhancement on 3D T1 images may suggest migraine severity and be predictive of neuronal loss.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
