[Tumors of the lateral ventricle. Review of 284 cases].
The data from 284 cases of lateral ventricle (VL) tumors treated in 18 departments of Neurosurgery in France between 1995 and 2010 were collected in this series. The mean age was 33 years with a large proportion of children (79/284).


METHODS
The mean duration of symptoms was short in time (2 months). The revelation was incidental in 10% of the cases; for symptomatic lesions, raised intracranial pressure (ICP, due to hydrocephalus) and neuropsychological signs were the most frequent. Only one third of the patients had no CSF disorder.


RESULTS
The two most frequent tumors were meningiomas (40 cases, 15%) and neurocytomas (35 cases, 13%). The sub-ependymal giant cells astrocytomas, the ependymomas and sub-ependymomas were also common (11, 10 and 9% respectively).


CONCLUSIONS
A surgical procedure was performed in 258 patients, with the help of neuronavigation in one third of cases. The patients were most frequently operated with a transfrontal approach (40%). The resection was complete in 73%, which was a statistical factor of global survival. The postoperative mortality rate was 4.9%.


RESULTS
Neuropsychological deficits were the most frequent sequelae (22.8%) due to raised ICP. Campimetric deficits (19%), seizures (19%), hemiparesis (15%) and language disorders (12%) were then found. The mean follow-up was 52 months with good evolution for 58% of patients. Fifteen percent of patients had a handicap and, finally, 12.9% will die. At last, two third of living patients had no tumoral residue or re-evolution.
