Abstract

Purpose: Sporadic hemiplegic migraine (SHM) is characterized by a prolonged motor aura that accompanies a migraine attack, and its underlying pathophysiology remains unclear. Functional image during the event can help to explore the mechanism.

Case report: We report a finding of 18-fluorodeoxyglucose positron emission tomography (FDG-PET) in a 15-year-old female with SHM. She presented with recurrent right arm weakness and pain with migrainous headache. A video electroencephalogram showed no evidence of epilepsy during the events. Subtraction of ictal-interictal FDG-PET coregistered to magnetic resonance imaging was performed for the image analysis. In comparison with the interictal state, the FDG-PET image showed decreased glucose metabolism in the bilateral dorsal lateral frontal cortices and bilateral occipital cortices, whereas increased metabolism in the left precentral motor cortex and right premotor cortex.

Conclusion: These findings reveal an increase in metabolism in the motor cortex during general cortical dysfunction in the frontal and occipital cortices in SHM. Key words: FDG-PET, hemiplegic migraine, migraine, positron emission tomography, SISCOM.

散发性偏瘫偏头痛FDG-PET表现的初间比较。

目的:散发性偏瘫性偏头痛(SHM)的特点是伴随偏头痛发作的运动先兆延长，其潜在的病理生理尚不清楚。事件过程中的功能形象有助于探究其发生机制。病例报告:我们报告一个发现18-氟脱氧葡萄糖正电子发射断层扫描(FDG-PET)在一个15岁的女性SHM。她表现为反复发作的右臂无力和疼痛伴偏头痛。视频脑电图显示事件期间没有癫痫的迹象。将FDG-PET共配准到磁共振成像中，进行头间期相减，进行图像分析。与间歇期相比，FDG-PET图像显示双侧背外侧额叶皮质和双侧枕叶皮质糖代谢减少，而左侧中央前运动皮质和右侧运动前皮质糖代谢增加。结论:这些发现揭示了SHM患者额枕皮质功能障碍时运动皮质代谢增加。关键词:FDG-PET，偏瘫性偏头痛，偏头痛，正电子发射断层扫描，SISCOM
