What causes pseudotumor cerebri?

The exact cause of pseudotumor cerebri is often unknown. It is suspected that the condition is a result of an increased amount of cerebrospinal fluid in the skull which results in increased intracranial pressure. Some medications such as birth control pills, lithium, and tetracycline can be risk factors. Cushing's disease, pregnancy, and obesity are also linked with pseudotumor cerebri.

The reason for decreased outflow of CSF is not clear. Because this condition seems to occur more often in overweight young women, a hormonal influence is suspected.

Overweight young women are 20 times more likely to develop pseudotumor. PTC may also occur in children, men, and patients who are not overweight. In some cases, antibiotic or steroid use may be associated with pseudotumor. High doses of vitamin A may also lead to increased CSF pressure.
