Teaching NeuroImages: Neuroimaging in hemiplegic migraine
2019年8月5日 · Hemiplegic migraine attacks can manifest from temporary hemiparesis to recurrent coma and prolonged hemiparesis, epilepsy, or mental retardation. 1 MRI abnormalities could only be detected in a few cases depending on the scan timing.

2024年6月5日 · In hemiplegic migraines, venous dilatation may be seen, best appreciated on on SWI MIP images contralateral to the hemiparesis 3. Changes in cerebral perfusion have also been described 3 . See the main article on hemiplegic migraines for a detailed discussion.
Migraine Associated Cerebral Hyperperfusion with Arterial Spin …
The 8 of 11 patients with a history of migraine, but who were asymptomatic during imaging, showed no perfusion abnormalities. ASL perfusion analysis may help identify patients with vascular or hemiplegic migraines by showing associated hypoperfusion during the aura state and hyperperfusion during the headache state (Figs 2–4). We believe that ...
Serial magnetic resonance imaging findings during severe attacks …
2021年4月21日 · Mutations in the ATP1A2 gene are responsible for Familial Hemiplegic type 2 (FHM2) or the sporadic hemiplegic migraine (SHM) counterpart if there is no family history of the disorder. Manifestations include migraine with aura and hemiparesis along with a variety of other symptoms likely dependent upon the specific mutation(s) present.

2023年7月4日 · Brain imaging like computed tomography (CT) and magnetic resonance imaging (MRI) head, cerebrospinal fluid (CSF) analysis, and electroencephalogram (EEG) may be required to rule out other pathologies, especially if the attacks are new in onset, have prolonged symptoms, and have no family history.

Diagnostic and therapeutic aspects of hemiplegic migraine
Imaging studies between attacks are normal, except in patients with FHM1 or SHM1 with cerebellar atrophy. 1 Swelling and/or cortical hyperintensity of the affected hemisphere have been described on T2/FLAIR-weighted MRI images performed during attacks. 54–56 Some patients present mild gadolinium enhancement on brain MRIs, probably due to an ...
Serial magnetic resonance imaging findings during severe attacks …
2021年4月21日 · Hemiplegic migraine (HM) is a subtype of migraine with aura, in which the aura has motor involvement, normally hemiparesis . HM can be further classified as familial (FHM) if at least one first-degree or second-degree relative also meets the criteria for HM; otherwise it is classified as sporadic [ 3 ].
Imaging abnormalities in sporadic hemiplegic migraine on …
Though initially confused with migrainous infarction, we suggest with sequential magnetic resonance imaging, magnetic resonance angiography, diffusion, perfusion images and magnetic resonance spectroscopy that the hemiplegia was not of vascular origin and that the patient had sporadic hemiplegic migraine.
Susceptibility-Weighted Imaging in Migraine with Aura
2011年1月1日 · SUMMARY: We report 2 patients with migraine with aura, in whom SWI showed transient prominence of the venous vasculature within areas of impaired perfusion. The findings resolved spontaneously in both patients. This imaging technique may play a helpful role in assessing the vascular events in migraine with aura.
