Description
Pseudotumor cerebri occurs when the pressure inside the skull (intracranial pressure) increases without any obvious cause. Symptoms are similar to a brain tumor but no tumor was found. This condition is commonly referred to as idiopathic intracranial hypertension (Iih).
Pseudotumor cerebri more common in children and adults, but the most commonly experienced are obese woman who was prolific childbearing.
Increased intracranial pressure associated with pseudotumor cerebri can also cause swelling of the optic nerve and loss of vision.
Cause
Experts suspect pseudotumor cerebri nothing to do with the excess amount of cerebrospinal fluid within the skull. In addition, the liquid produced by the brain will eventually be absorbed into the bloodstream. It could be an increase in intracranial pressure that causes pseudotumor cerebri is also a result of a disturbance in the absorption process.
According to some recent studies, the majority of patients with pseudotumor cerebri are known to experience a narrowing (stenosis) in the amount of two sinuses in the brain (transverse sinuses). But researchers are also not sure whether it is a narrowing of one of the causes of pseudotumor cerebri or not.
Symptom
- Moderate to severe headaches that come from the back of the eye and worse with eye movement.
- Ringing in the ears along with the heart rate of the patient.

- Difficult to see to the side
- Double vision (diplopia)
- As seen flashes of light when there is no source of light (photopsia)
- Neck pain, shoulder or back
Treatment
- Drugs such as glaucoma drug that acetazolamide, a diuretic and migraine medication.
- Operating the optic nerve sheath fenestration and installation of spinal fluid shunt.
