Epileptic opsoclonus due to cortical dysplasia of the left posterior temporal cortex: A simultaneous electroencephalogram and electrooculogram study

Abstract

This is the first report of opsoclonus seizures due to left posterior cortex epilepsy, which was documented with oculogram (see supplementary discussion) [1], scalp, and subdural EEG. The child has been seizure free for 44 months after resection of the left posterior temporal cortex. Review of literature and the index case support posterior cortex as the epileptogenic zone of ictal opsoclonus.
