Idiopathic intracranial hypertension (IIH) is a disease defined by an increase of intracranial pressure of unexplained cause, which manifests predominantly in overweight women of childbearing age ^1-7. MRI and MR cerebral venography are essential tools for the diagnosis of clinically suspected IIH ^1-7. Transverse sinus stenosis is the most sensitive finding of this disease. ^1,4,7.

The diagnosis of idiopathic intracranial hypertension, in this case, was based on a combination of clinical presentation, brain imaging findings, and a lumbar puncture that indicated elevated opening pressure.
