Chronic intracranial hypertension can be caused by many conditions including certain drugs such as tetracycline, a blood clot in the brain, excessive intake of vitamin A, or brain tumor. It can also occur without a detectable cause. This is idiopathic intracranial hypertension (IIH). Because the symptoms of IIH can resemble those of a brain tumor, it is sometimes known by the older name pseudotumor cerebri, which means âfalse brain tumor.â.
