Patients with DNET constitute a group with favorable outcomes after epilepsy surgery especially with early referral to surgery. Longer duration of epilepsy was associated with worse seizure outcome for DNET patients. There was significant correlation between radiological and histopathological types of DNET especially in type 1 and 3.

The aim of this paper is to provide the long-term surgical outcome of patients with intracranial intraventricular tumors. Materials and methods:Twenty-five patients operated on for intraventricular tumors between June 1999 and June 2014 are reviewed. Data from before, during, and after surgery were obtained from the patients' files and patients were followed regularly after surgery. Results:The group of patients comprised 15 females and 10 males with a mean age of 31.6 ± 16 years. The majority were adults and only 3 children were included. Three, 4, and 18 patients had tumors in the 4th, 3rd, and frontal horn of the lateral ventricles, respectively. All patients showed a varying degree of hydrocephalus and headache was the most common presenting symptom. Overall, central neurocytoma was the most common pathological diagnosis. Complications were found in only 4 patients and, in long-term follow-up, 3 patients had died due to the malignant nature or upgrading to a malignant tumor and the rest were alive. Conclusion:Total removal of the intraventricular tumor increases survival because the majority of these tumors are benign and slowgrowing. The type of surgical intervention should be chosen according to the location of the tumor in the ventricular system.
