Crossed Cerebellar Diaschisis in Status Epilepticus

Crossed Cerebellar Diaschisis in Status Epilepticus NEUROCRITICAL CARE Samaniego, E. A., Stuckert, E., Fischbein, N., Wijman, C. A. 2010; 12 (1): 88-90

Abstract

Crossed cerebellar diaschisis (CCD) has been reported on positron-emission tomography and single-photon emission computed tomography of stroke patients. Rarely it has been described with brain diffusion-weighted MRI (DWI) of status epilepticus (SE).Case report.A 53-year-old woman was found unresponsive after cocaine use. A diagnostic electroencephalogram was consistent with ictal SE. A brain DWI showed reduced diffusion in the left temporo-parietal and occipital cortexes, the left thalamus and the right cerebellum. The DWI changes did not correspond to a vascular territory and were attributed to seizure activity and secondary CCD. A 2-week follow-up DWI showed interval near-complete resolution of the diffusion changes. CCD in SE may represent injury caused by excessive neuronal transmission from prolonged excitatory synaptic activity via the cortico-pontine-cerebellar pathway. Alternatively, it may be a result of interruption of the cortico-pontine-cerebellar pathway with loss of cortical inhibitory input.This case documents CCD during SE, providing further evidence of contralateral cerebellar involvement with a supratentorial epileptiform focus.
