pseudotumor cerebri
Increased pressure
within the brain in the absence of a tumor.
Pseudotumor cerebri can cause headache, ringing
in the ears, double vision, loss of visual accuracy,
and even complete blindness. It is most common in
obese woman of childbearing age. Although its
cause is usually not known, pseudotumor cerebri is
sometimes linked to use of tetracycline, nalidixic
acid, nitrofurantoin, phenytoin, lithium, or amio-
darone, or overuse of vitamin A. Diagnosis is made
via brain imaging and lumbar puncture. Drugs to
reduce cerebrospinal fluid production or hyperos-
motic drugs may be used to reduce fluid buildup.
Excess cerebrospinal fluid may be removed with
repeated spinal taps, shunting, or a type of surgery
called optic nerve sheath fenestration that allows the
excess fluid to escape. Steroids may be prescribed
to reduce swelling of brain tissue. Also known as
benign intracranial hypertension, idiopathic
intracranial hypertension (IIH).
