The aim of this study is to report a possible implication of augmented vasogenic leakage in the mechanism of prolonged aura in sporadic hemiplegic migraine. A 35-year-old woman with sporadic hemiplegic migraine presented with headache followed by right arm weakness, right visual field defect, aphasia and confusion that persisted for 1 week. During the acute stage, focal hyperaemia was seen in the left cerebral hemisphere corresponding to persistent aura symptoms. Augmented vasogenic leakage was demonstrated on delayed enhanced fluid-attenuated inversion recovery image. Magnetic resonance angiography showed dilation of the left middle cerebral artery. During the convalescent stage, such abnormal findings were not seen. Based on these results, we speculate that augmented vasogenic leakage from the leptomeningeal vessels, probably associated with activation of the trigeminovascular system, may delay the recovery of hemiplegic migraine aura.
