Reversible imaging abnormalities consistent with CSD during migraine without aura attack

An 18-year-old man with a history of migraine without aura and normal neurological examination carried out a cerebral CT scan during a spontaneous typical migraine attack. While the CT scan demonstrated left temporal-parietal-occipital low attenuation, a brain magnetic resonance imaging, performed 5 days later, did not show any lesions. Based on this evidence, we can speculate that the dysfunction of the cerebrovascular system, either in the cerebral cortex or in the subcortical regions, is an important mechanism in the pathophysiology of migraine.
