[Tumors of the lateral ventricle in child: characteristics and specificities].

Tumors of the lateral ventricle are not as rare in children as in adults and present complex problems which are to be dealt with often in a context of emergency, on account of their large size and the risk of life-threatening bleeding in a small child. Their diagnostic features are different in children, especially in infants and even more so in the fetus. The main surgical problems are the risk of bleeding and of hydraulic complications. From an oncological perspective, the main tumor types are choroid plexus tumors, subependymal giant-cell astrocytoma, and low-grade gliomas. The developmental outcome of these patients is often poor, on account of severe intracranial hypertension and young age at diagnosis.
