G94.2: Hydrocephalus in other diseases classified elsewhere

Cerebrospinal fluid has accumulated in your skull.

There are cavities with cerebrospinal fluid in the brain, around the brain and around the spinal cord. Among other things, the cerebrospinal fluid cushions the brain and spinal cord during knocks and also nourishes the brain cells.

The cerebrospinal fluid is produced in the cavities in the brain. The various cavities for cerebrospinal fluid are connected to one another. So the cerebrospinal fluid is able to flow through the different cavities in the brain to the space around the brain. The cerebrospinal fluid is reabsorbed in the cavity around the brain. Normally exactly as much cerebrospinal fluid is produced as is reabsorbed.

If the cerebrospinal fluid is unable to flow unhindered from the cavities in the brain, it can accumulate there. This can occur, for example, if inflamed or changed tissue presses on the connecting passages between the brain’s cavities. A bleed can also prevent the cerebrospinal fluid from flowing away.

If a lot of cerebrospinal fluid collects in the skull, the pressure in the skull can increase. You may then feel dizzy or nauseous.

Some other condition has caused cerebrospinal fluid to accumulate in your skull.
