Pseudotumor cerebri is a disorder related to high pressure in the brain that causes signs and symptoms of a brain tumor—hence the term “pseudo” or false tumor. Pseudotumor cerebri is also sometimes known as intracranial hypertension or benign intracranial hypertension.

Dr. Brian Gay from First Look MRI explains how to read a brain MRI scan for Pseudotumor cerebri.

Pseudotumor cerebri happens when the fluid that surrounds the spinal cord and the brain—called cerebrospinal fluid—accumulates abnormally in the brain. This accumulation of fluid may be because of an increase in fluid production or a decrease in fluid absorption.
