Hydrocephalus
Hydrocephalus is the term used to describe a condition of abnormal dilation of the ventricular system within the cranium. Hydrocephalus can result from obstruction of the ventricular system, irritation of the ventricle (from inflammation or hemorrhage), increased size of the ventricles due to loss of brain parenchyma (hydrocephalus ex vacuo); it will rarely be the result of overproduction of CSF associated with a choroid plexus tumor, or be present without an obvious cause (congenital). Hydrocephalus may also be associated with cystic spinal cord abnormalities, such as syringomyelia and hydromyelia.
