Intracranial hypertension syndrome, also known as idiopathic intracranial hypertension or pseudotumor cerebri, is a condition characterized by increased pressure within the skull. Some common synonyms for this condition include benign intracranial hypertension, primary intracranial hypertension, and cerebral venous hypertension. These terms are used interchangeably to describe the same medical condition that is caused by several factors. Although the exact causes of intracranial hypertension syndrome remain unknown, symptoms such as headaches, visual disturbances, and tinnitus can be managed with medications and in some cases, surgical interventions. Treatment is crucial to manage the underlying cause of the condition and prevent potential complications.
