Modern Imaging of Pediatric Hydrocephalus

  • Francis Brunelle
Chapter

Abstract

Hydrocephalus is defined as an increased volume of intracranial CSF. It is usually but not always associated with an increase in intracranial pressure. CSF accumulates in the ventricles, which become enlarged, or around the periphery of the brain (so-called external hydrocephalus). In acute hydrocephalus the ventricles may not have time to dilate, while with chronic hydrocephalus the ventricles may be very large. A new equilibrium between reabsorption and production of CSF is then reached at a higher pressure.
