Pseudotumor Cerebri is a condition characterized by increased pressure in the skull without the presence of a tumor. It often leads to symptoms such as headaches, vision problems, and ringing in the ears. The exact cause is not fully understood, but it is commonly associated with obesity and certain medications. Diagnosis typically involves imaging tests like MRI or CT scans to rule out other conditions. Treatment may include weight loss, medications to reduce pressure, or in some cases, surgical options. Early detection is crucial to prevent potential vision loss and other complications.
