Idiopathic Intracranial Hypertension is also called Pseudotumor cerebri syndrome and benign intracranial hypertension. It is a syndrome of raised intracranial pressure and papilledema, without mass lesion or enlarged ventricles. Prior to its diagnosis all other causes of raised intracranial pressure need to be excluded. It is more common in women (4-8 times more common) and is associated with obesity (over 93% of patients are obese). There has also been an association with a number of drugs including anti- acne medications and tetracycline antibiotics.
