[Tumors of the cerebral hemispheres in children and adolescents. Results of treatment, residual syndromes and focal epilepsy].

Tumors of the cerebral hemispheres comprise a big variety of histologic tumor types. Therefore, in the literature usually only specific subgroups such as benign gliomas and temporal lobe tumors are reported. In this study we report on 44 tumors of the cerebral hemispheres, including 9 angiomas. Apart from the treatment results concerning event free survival, the neurological and neuropsychological outcome of the patients were assessed. A peculiarity in the hemispheric tumors is their association with focal epilepsies. In 94% of our patient series, epileptic seizures had been the first tumor associated symptom and approximately 62% developed focal epilepsy. Seizure types, their association with tumor location and histology, the success of tumor therapy in concern of the epilepsy and the significance of the electroencephalogram in the follow up care of these patients were assessed separately.
