Abstract

Utilizing a ventricular perfusion technique, the rate of CSF formation was determined in a 2-year-old child before and after removal of a 74 g choroid plexus papilloma from the left lateral ventricle. Preoperatively, the CSF formation rate was 1.05 +/- SD 0.01 ml/min (1,656 ml/day). Postoperatively, the CSF formation rate was reduced fivefold to 0.20 +/- SD 0.01 ml/min (288 ml/day). Whereas these data are regarded as conclusive evidence of CSF overproduction by a choroid plexus papilloma, the pathogenesis of generalized ventricular enlargement in this case was due to part to obstruction of the subarachnoid pathways.
