Overview Hydrocephalus is the buildup of fluid in the cavities (ventricles) deep within the brain. The excess fluid increases the size of the ventricles and puts pressure on the brain. Cerebrospinal fluid normally flows through the ventricles and bathes the brain and spinal column.

Hydrocephalus Not to be confused with Hypocephalus or Hydranencephaly. Hydrocephalus is a condition in which there is an abnormal accumulation of cerebrospinal fluid (CSF) within the brain. This typically causes increased pressure inside the skull. Older people may have headaches, double vision, poor balance, urinary incontinence, personality changes, or mental impairment.

Intraventricular Hemorrhage What is intraventricular hemorrhage? Intraventricular hemorrhage (IVH) of the newborn is bleeding into the fluid-filled areas, or ventricles, surrounded by the brain. The condition is most often seen in premature babies, and the smaller and more premature the infant, the higher the risk for IVH.

Hydrocephalus Hydrocephalus is due to a problem with the flow of the fluid that surrounds the brain. This fluid is called the cerebrospinal fluid, or CSF. The fluid surrounds the brain and spinal cord and helps cushion the brain. CSF normally moves through the brain and the spinal cord and is soaked into the bloodstream. CSF levels in the brain can rise if: 1  The flow of CSF is blocked.  The fluid does not get properly absorbed into the blood.

What is Hydrocephalus? Hydrocephalus may also be acquired as a result of brain tumors or cysts. Most brain tumors are detected in children between the ages of five and ten years old. Seventy-five percent of these tumors occur in an area at the back of the brain, known as the posterior fossa.

Causes Congenital hydrocephalus. Congenital hydrocephalus (when a baby is born with the condition) may be the result of a defect in the development of the brain that restricts the flow of CSF. This can be caused by certain health conditions, such as spina bifida.

- These sutures, or soft spots, haven't hardened yet, and stretch and expand to store the excess CSF. As a result, a baby with hydrocephalus will appear to have an oddly shaped head — usually much larger than other babies the same age. Other signs to look for include: bulging at the soft spots split sutures — a gap can be felt between skull bones

Learn how UpToDate can help you. Hydrocephalus is the correct term for pathologic dilatation of the brain's ventricular system from increased pressure, usually due to obstruction. Ventriculomegaly is the appropriate term when dilatation is due to other causes, such as brain dysgenesis or atrophy.

Genetics of human hydrocephalus Human hydrocephalus is a common medical condition that is characterized by abnormalities in the flow or resorption of cerebrospinal fluid (CSF), resulting in ventricular dilatation. Human hydrocephalus can be classified into two clinical forms, congenital and acquired.

Classifications and Causes Aqueductal stenosis – The most common cause of congenital hydrocephalus is an obstruction called aqueductal stenosis. This occurs when the long, narrow passageway between the third and fourth ventricles (the aqueduct of Sylvius) is narrowed or blocked, perhaps because of infection, hemorrhage, or a tumor.

- Hydrocephalus (also called water on the brain) can make babies' and young children's heads swell to make room for the excess fluid. Older kids, whose skull bones have matured and fused together, have painful headaches from the increased pressure in the head.

Causes The causes of hydrocephalus are poorly understood. It's thought that congenital hydrocephalus may be the result of a brain defect restricting the flow of cerebrospinal fluid. Acquired hydrocephalus is often caused by an illness or injury that affects the brain.

Hydrocephalus Hydrocephalus may be congenital or acquired. Congenital hydrocephalus is present at birth and may be caused by either events or influences that occur during fetal development, or genetic abnormalities. Acquired hydrocephalus develops at the time of birth or at some point afterward.

What Is Ventriculomegaly? Fetal ventriculomegaly is a condition in which a fetus's brain ventricles (cavities) are abnormally enlarged. Ventriculomegaly may be mild or severe.Symptoms and treatment vary by its severity.ymptoms of Ventriculomegaly. After birth, mild ventriculomegaly may not produce any symptoms or signs. If the condition is severe or caused by worsening hydrocephalus (CSF buildup in the brain), your baby may have one or more of these symptoms: 1  Full or bulging soft spot (fontanel) on the newborn's skull.

Protection of the Brain Hydrocephalus. Introduction. Hydrocephalus is a condition that occurs when there is too much cerebrospinal fluid in the ventricles (cavities) of the brain. Cerebrospinal fluid (CSF) is produced in the brain, and is needed by the body to protect the brain and spinal cord, and carry away waste from brain cells.It flows continuously through the ventricles of the brain and over the surface of the brain and spinal cord.ydrocephalus.

Adult-onset Hydrocephalus The term hydrocephalus is derived from two words: hydro, meaning water, and cephalus, referring to the head. Hydrocephalus is a condition in which excess cerebrospinal fluid (CSF) builds up within the ventricles (fluid-containing cavities) of the brain and may increase pressure within the head. Although hydrocephalus often is described as water on the brain, the water is actually CSF — a clear fluid surrounding the brain and spinal cord.

Hydrocephalus and toy breed dogs Hydrocephalus and toy breed dogs. Hydrocephalus or “water in the brain” is condition of the head that can occur in toy breed dogs as well as other canines. Hydrocephalus increases pressure in the skull and results in swelling of the head. Hydrocephalus is caused by abnormal dilation of the ventricular system as a result of increased spinal fluid.

- Hydrocephalus is an abnormal accumulation of cerebrospinal fluid (CSF) in the ventricles, or cavities, of the brain, which may cause increased intracranial pressure (ICP) inside the skull. It may lead to enlargement of the cranium if hydrocephalus occurs during development.he brain produces roughly 500 mL of cerebrospinal fluid per day. This fluid is constantly reabsorbed, so that only 100-160 mL is present at any one time.

Hydrocephalus Signs and symptoms. Clinical features of hydrocephalus are influenced by the patient's age, the cause of the hydrocephalus, the location of the obstruction, its duration, and its rapidity of onset. Symptoms in infants include poor feeding, irritability, reduced activity, and vomiting.

Overview Hydrocephalus is caused by an imbalance between how much cerebrospinal fluid is produced and how much is absorbed into the bloodstream. Cerebrospinal fluid is produced by tissues lining the ventricles of the brain. It flows through the ventricles by way of interconnecting channels and eventually flows into spaces around the brain and spinal column. It's absorbed primarily by blood vessels in tissues near the base of the brain.

HYDROCEPHALUS There are many different conditions that may cause hydrocephalus. These consist of a genetic disorder, birth defect, infection, head injury, meningitis, and hemorrhage into the brain. In a birth defect, the cause is most likely an obstruction of the CSF flow in the bloodstream.
