[Hyperproduction of CSF in choroid plexus papillomas in children].
Two cases of papilloma of the choroid plexus in children, one in the fourth ventricle and the other in the central part of the left lateral ventricle, are reported. Hyperproduction of CSF could be suspected in the first case by the productive character of pre-operative external ventricular drainage and demonstrated in the second by measurement of pre and post-operative flow rates through a ventriculo-peritoneal bypass which had been installed previously. The origin of this over-production of CSF is discussed, in the pathogenesis of hydrocephalus, in comparison with other factors such as subarachnoid haemorrhage, hyperproteinorachia impairing the resorption of CSF.
