A case of hemiplegic migraine in childhood: transient unilateral hyperperfusion revealed by perfusion MR imaging and MR angiography.
We report on an 8-year-old girl with a typical attack of hemiplegic migraine, in whom MR angiography and perfusion MR imaging revealed unilateral dilation of branches of both the middle and posterior cerebral arteries and hyperperfusion of the ipsilateral hemisphere, respectively. The findings resolved spontaneously after the attack. These imaging techniques should be indicated for patients with migraine attacks and may play a role in assessing the vascular events in migraine headache.
