Children with cerebral palsy who are treated with intrathecal baclofen have a higher rate of cerebrospinal fluid (CSF) leaks along the baclofen catheter than do adults treated with intrathecal baclofen. We postulated that the cause of the increased frequency of CSF leaks was increased CSF pressure, that is, occult hydrocephalus. METHODS: Lumbar punctures were performed in 24 children with cerebral palsy and asymptomatic ventriculomegaly. Their median age was 4.7 years. Mild or moderate ventriculomegaly was present in 23 children and severe ventriculomegaly was present in 1 child. RESULTS: Opening pressures were abnormally high in 23 (96\%) of 24 children and ranged from 22 to 41 cm H2O (mean, 27.3 cm H2O). Opening pressures did not correlate with the extent of ventriculomegaly. CONCLUSION: Children with cerebral palsy and ventriculomegaly seem to have a high incidence of increased CSF pressure, and thus, of occult hydrocephalus. The increased pressure is probably a significant cause of the increased frequency of CSF leaks for these children during intrathecal baclofen therapy. The long-term risks of untreated increased CSF pressures in this patient population are not known but are cause for concern. Treatment with CSF shunts offers the potential of improved development, which was reported anecdotally in some children who were treated with ventriculoperitoneal shunts after their pressure was found to be increased. Prospective multicenter studies of this problem are needed.
