Cerebrospinal fluid overproduction and hydrocephalus associated with choroid plexus papilloma

Abstract
✓ With the use of a ventricular perfusion technique, a cerebrospinal fluid formation rate of 1.4 ml/min was determined in a 5-month-old child with a choroid plexus papilloma and hydrocephalus. This rate was slightly greater than four times the rate observed in normal children. The clinical course, as well as a measured absorption rate, indicated that the patient's capacity for absorption was normal.
