Familial hemiplegic migraine with prolonged aura and multimodality imaging: a case report.

We report a case of familial hemiplegic migraine with prolonged aura where multimodality imaging showed hemispheric cytotoxic edema along with evidence of hypometabolism in the affected hemisphere while there was no evidence of hypoperfusion of the affected hemisphere demonstrating that neuronal depression is a more plausible explanation in its pathogenesis.
