General Information About Pseudotumor Cerebri
Disease Details and Frequently Asked Questions
It is a condition where the fluid pressure inside the skull (ICP) rises to extremely high levels as if a massive tumor were present, but an MRI scan shows the brain to be completely clear (tumor-free).
The disease most frequently occurs in overweight (obese) women between the ages of 20 and 40 or those who have gained weight rapidly. Birth control pills or certain acne medications (Vitamin A derivatives) can also trigger it.
Symptoms include severe headaches that worsen at night or upon waking in the morning, a ringing sound in the ears synchronized with the pulse (pulsatile tinnitus), momentary vision blackouts, and double vision.
Yes, this is the most dangerous aspect of the disease. The high fluid pressure in the brain directly compresses the optic nerve (papilledema). If left untreated, the nerve dies, leading to irreversible blindness.
A fundus examination reveals swelling of the optic nerve. A brain MRI is performed to prove the absence of a real tumor. Finally, fluid is drawn from the lower back (Lumbar Puncture) to numerically measure the cerebrospinal fluid pressure, confirming the diagnosis.
Weight loss is the most crucial step in treatment for obese patients. Special pills (Acetazolamide) that facilitate the excretion of brain fluid through urine are prescribed. If the pressure cannot be reduced with medication and there is a risk of vision loss, a tube (Shunt Surgery) is inserted to drain the excess fluid into the abdominal cavity.
