Pseudotumor cerebri notes

Pseudotumor cerebri

Associated with:
Obesity
Vitamin A toxicity

Signs and symptoms:
Headache
Sixth nerve palsy
Visual field defects
Pulsutile tinnitus

Diagnosis:
Papilledema
To rule out space occupying lesions - CT / MRI normal
Most accurate - Lumbar puncture with opening CSF pressure measurement

Treatment:
Weight loss
Acetazolamide
Surgery

Why does increased ICP cause 6th nerve (Abducens) palsy?
Increased ICP can result in downward displacement of the brainstem, causing stretching of the sixth nerve secondary to its location within  Dorello's canal.

That's all!
