[Corpus callosum agenesis and epilepsy in 2 brothers]

We report on two brothers with focal epileptic seizures and agenesia of the corpus callosum. The diagnosis of agenesia of the corpus callosum in both was made by CT, both brothers were retarded and both showed focal phenomena which can be interpreted as a consequence of the lacking connection between the two hemispheres. One of the patients showed a remarkable focal miniature spike and wave periodicity in the EEG. Neither of the parents had matching abnormalities.
