Crossed Cerebellar Diaschisis in Complex Partial Status Epilepticus / 대한간질학회지

ABSTRACT

Crossed cerebellar diaschisis has been described mostly in hemispheric stroke and supratentorial tumors with positron-emission tomography (PET) and single photon emission computed tomography (SPECT). Rarely it has been described with brain diffusion-weighted MRI of status epilepticus. We report a patient with status epilepticus, who developed MRI abnormalities in the cerebral cortex and contralateral cerebellum. EEG abnormalities correlated anatomically with the cerebral cortex of image change. An aggressive medication resulted in seizure control, reversal of neurologic deficit, and improvement or resolution of the MRI and EEG abnormalities in 3 weeks. We concluded that both localization and resolution of lesions may be explained by reversible excitotoxic cell damage due to seizure-related excessive synaptic activity.
