Pseudotumor cerebri, also known as idiopathic intracranial hypertension, is a condition where the pressure inside the skull increases without a known cause, leading to symptoms that mimic those of a brain tumor. It’s characterized by elevated intracranial pressure and can cause vision problems and severe headaches.
Key aspects of Pseudotumor Cerebri:
Increased Intracranial Pressure:
The primary issue is elevated pressure within the skull, often due to a buildup of cerebrospinal fluid.
No Known Cause:
The cause of the increased pressure is often unknown, hence the term “idiopathic”.
Mimicking Brain Tumor Symptoms:
Symptoms can include severe headaches, vision problems (like blurred or double vision, vision loss, or transient blindness), and ringing in the ears (tinnitus).
Diagnosis:
Diagnosis typically involves a thorough neurological exam, imaging studies (MRI or CT scans), and a lumbar puncture to measure intracranial pressure.
