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 migrain e, in whom MR angiography and perfusion MR imaging revealed unilateral dila tion of branches of both the middle and posterior cerebral arteries and hyp erperfusion of the ipsilateral hemisphere, respectively. The findings resol ved spontaneously after the attack. These imaging techniques should be indi cated for patients with migraine attacks and may play a role in assessing t he vascular events in migraine headache.
