How is communication different from non-communicating hydrocephalus?

The word “communicating” refers to the fact that CSF can still flow between the ventricles, which remain open. Non-communicating hydrocephalus – also called obstructive hydrocephalus – occurs when the flow of CSF is blocked along one or more of the narrow passages connecting the ventricles.

What causes communicating hydrocephalus?

Communicating hydrocephalus occurs when the flow of CSF is blocked after it exits the ventricles. This form is called communicating because the CSF can still flow between the ventricles, the passages between which remain open.

How is non-communicating hydrocephalus treated?

Some individuals with non-communicating (obstructive) hydrocephalus can have a surgical procedure called an endoscopic third ventriculostomy (ETV). This surgery creates an opening to allow CSF to flow in and around the brain as it would do under normal circumstances.

What is hydrocephalus radiology?

The most commonly accepted definition of hydrocephalus is “…active distention of the ventricular system of the brain resulting from inadequate passage of CSF from its point of origin within the cerebral ventricles to its point of absorption into the systemic circulation.

How is communicating hydrocephalus treated?

Patients with communicating hydrocephalus benefit from placement of a ventriculoperitoneal or ventriculoatrial shunt. Depending on the etiology of the hemorrhage, specific valves are used that have MRI lock features or off-valve settings to help manage the patients through their conditions.

Can hydrocephalus be seen on an MRI?

Congenital and acquired hydrocephalus CT scans and MRI scans are often used in combination to confirm a diagnosis of hydrocephalus present from birth (congenital) and hydrocephalus that develops later in children and adults (acquired). These scan the brain in detail.

What are symptoms of communicating hydrocephalus?

In older children and adults, symptoms may include one or more of the following: headache, vomiting, nausea, downward deviation of the eyes (called “sunsetting”), problems with balance, poor coordination, gait disturbance, urinary incontinence, slowing or loss of development, lethargy, drowsiness, irritability, or …

Can MRI show fluid build up?

MRI scans use a magnetic field and radio waves to create computerized, three-dimensional images of the ear and the nerve that carries signals from the inner ear to the brain. An MRI scan may reveal a buildup of fluid or inflammation in the inner ear or a growth on the nerve.

What are the symptoms of water on the brain?

Water on the brain can also cause symptoms like vomiting, nausea, vision problems, seizures, sleepiness, and developmental delays. When these symptoms present in a patient, a doctor can order a medical imaging study to look at the brain and learn more about what is causing the patient’s symptoms.

What is the treatment for water on the brain?

It is not possible to cure water on the brain, but the condition can be treated. Treatment involves inserting a shunt into the brain to provide a drainage method. The shunt is a flexible plastic tube which drains to another portion of the body which can reabsorb and eventually express the cerebrospinal fluid.

What is the treatment for fluid on the brain?

Treating Fluid on the Brain. The treatments for fluid on the brain will differ from person to person depending on the cause. The most common treatment is the surgical insertion of a shunt that allows the CSF to flow to a different area of the body and become absorbed by the circulatory system.

What is obstructive hydrocephalus?

Obstructive hydrocephalus (also called non-communicating hydrocephalus) is a form of hydrocephalus which is caused by some visible blockage in the flow of cerebrospinal fluid.
