Intraventricular tumors account for approximately 3% of adult brain tumors and 16% of childhood and adolescent brain tumors, so they are relatively infrequent and outside the usual experience of most neurosurgeons. The aim of this study is to present our results of surgical management to cerebral intraventricular tumors and try to find out the prognostic factors of these patients. We conduct a retrospective chart review of 27 patients at Kaohsiung Veterans General Hospital from January 1991 to December 2010 who admitted to our service and had undergone surgical treatment to their cerebral intraventricular tumors. The mean age of these 27 patients was 48.04 years (ranged from 15 years old to 83 years old). 18 of them were male; 9 patients were female. Totally, there were 34 tumor resection procedures done on them, in which 21 procedures were done microscopically; 12 procedures were done endoscopically, and 1 patient just underwent stereotactic biopsy of the tumor. 14 patients had good outcome (GOS score = 4 or 5); 9 patients had poor outcome (GOS score = 2 or 3). There were 4 cases of surgical mortality. 12 patients had permanent CSF shunt procedures, and 1 of them removed the shunt 2 years later and did not need further CSF shunting during the follow-up. From this limited study, we find by cumulative logistic regression and complementary log-log regression that age of patients, histology of the tumors, tumor locations and the development of complications are possible factors impacting the prognosis of patients harbouring cerebral intraventricular tumors. Surgical management to the cerebral intraventricular tumors remains a challenge to most neurosurgeons. The strategy of management to the intraventricular tumors should be tailored to each individual based on the size, location, consistency, and histology of the tumors. Multidisciplinary approaches are the way.
