Idiopathic Intracranial Hypertension: Pre- and Post-treatment Radiologic Analyses.

We discuss a case of a 19-year-old female who presented with pressure headaches and progressive vision loss. In the emergency department, a series of diagnostic tests were conducted, including CT, MRI, and lumbar puncture with measurement of opening pressure. All these examinations yielded results consistent with the suspected diagnosis of idiopathic intracranial hypertension (IIH). The patient was treated with acetazolamide to reduce intracranial pressure, resulting in the resolution of symptoms and the normalization of intracranial pressure on imaging studies. She was subsequently discharged from the hospital seven days after her initial presentation.
