Clinical Information

• hye-dro-sef-uh-lus) the abnormal buildup of cerebrospinal fluid in the ventricles of the brain.

• A disorder characterized by an abnormal increase of cerebrospinal fluid in the ventricles of the brain.

• Excessive accumulation of cerebrospinal fluid within the cranium which may be a congenital or acquired disorder; hydrocephalus ex-vacuo refers to ventricular dilation that occurs as a result of brain substance loss from cerebral infarction and other conditions.

• Excessive accumulation of cerebrospinal fluid within the cranium which may be associated with dilation of cerebral ventricles, intracranial hypertension; headache; lethargy; urinary incontinence; and ataxia.

• Excessive gathering of cerebrospinal fluid within the head bone

• Hydrocephalus is the buildup of too much cerebrospinal fluid in the brain. Normally, this fluid cushions your brain. When you have too much, though, it puts harmful pressure on your brain.there are two kinds of hydrocephalus. Congenital hydrocephalus is present at birth. Causes include genetic problems and problems with how the fetus develops. An unusually large head is the main sign of congenital hydrocephalus. Acquired hydrocephalus can occur at any age. Causes can include head injuries, strokes, infections, tumors and bleeding in the brain. Symptoms of acquired hydrocephalus can include

• Hydrocephalus that results from head trauma, brain tumors, intracranial hemorrhage, or meningitis.

• The abnormal buildup of cerebrospinal fluid in the ventricles of the brain.
