Two Cases of Crossed Cerebellar Diaschisis with or without Thalamic Lesion on Brain MRI in Status Epilepticus

Abstract

We report two cases of status epilepticus who showed crossed cerebellar diaschisis (CCD) with or without pulvinar high signal intensity (HSI) on brain magnetic resonance imaging (MRI). The first patient had CCD with pulvinar HSI on MRI and periodic lateralized epileptiform discharges (PLEDs) on electroencephalography. MRI of the second patient revealed CCD without pulvinar HSI. And electroencephalography (EEG) of this patient did not show PLEDs. The authors suggest that the pulvinar lesion might be related to the generation of PLEDs in Status epilepticus.
