title: [Pediatric intraventricular tumors].
abstract: Pediatric intraventricular tumors present a well circumscribed group from surgical point of view. These tumors growing in the ventricular system cause hydrocephalus in most of the cases, the presenting symptoms are the signs of raised intracranial pressure. The mass lesion may remain silent for a long period, especially in infancy due to compensatory mechanisms, and the tumor might reach extreme size making the surgery a real challenge. This group has very specific postoperative problems resulting from the disturbance of CSF circulation. In this study we present the retrospective analysis of 55 patient operated for intraventricular tumor in the National Institute of Neurosurgery between 1991 and 2006. Data were analysed regarding histological type, presenting symptoms, type of surgical approach, radicalitiy of the resection and postoperative complications. In addition to our own results brief presentation of the specific histological groups is given based on the available literature.
