Abstract: Diffusion-weighted magnetic resonance images and brain blood
perfusion scintigraphy are useful tools in identifying the cause of cerebral
lesions. We report serial simultaneous diffusion-weighted magnetic resonance
images and brain blood perfusion scintigraphy of
hemiconvulsion-hemiplegia-epilepsy syndrome. In this case, the involved
hemisphere revealed high intensity on diffusion-weighted images and slight
hyperperfusion on brain blood perfusion scintigraphy 7 days after the seizure.
Accordingly, neurotoxic, rather than ischemic, cellular edema might be the
cause of hemiconvulsion-hemiplegia-epilepsy syndrome in the acute phase.
