Headaches are common in the clinical setting. Fortunately, intracranial hypertension (IH) is rare, but when present it can lead to significant morbidity. Early diagnosis and proper management are important to lessen the potential morbidity. Careful headache history, ophthalmologic examination, head imaging, and lumbar puncture (LP) are crucial tools in the diagnosis of this condition. Management should be coordinated with a neurologist, ophthalmologist, or neuro-ophthalmologist.
