B26.1: Mumps meningitis

You have mumps. The mumps virus has also spread to the linings of your brain.

Mumps is caused by viruses. With mumps, your face swells up in front of and behind your ear. Both sides of your face may be affected. Your face may then be painful. You may also get a fever.

The mumps virus has inflamed the linings of your brain. On the outside of the brain and spinal cord there are three thin meninges (linings). A tough meninx, the dura mater, is on the outside. Below that are two soft meninges. When the meninges are inflamed, this can cause various symptoms. It is also possible to get a high fever and feel very sick. Severe headaches and a stiff neck are common. You may find it difficult to tolerate bright light and loud noises. Sometimes you may also feel nauseated and feel like you have to vomit. Seizures are also possible or you may lose consciousness.
