Disorders of Cerebrospinal Circulation: Idiopathic Intracranial Hypertension and Hydrocephalus

Show Summary Details

Preview

Two important diseases that illustrate the importance of understanding the anatomy and physiology of brain fluids are idiopathic intracranial hypertension (IIH) and hydrocephalus. Both involve excessive amounts of fluid in the brain, raising intracranial pressure. Treatment involves either reducing fluid production with medications or enhancing drainage by shunting brain fluids to sites outside the brain. A major difference is the size of the ventricles; in IIH the ventricles are normal or small, while the opposite is the case in hydrocephalus. Diagnosis of hydrocephalus has been remarkably simplified by computed tomography (CT) and magnetic resonance imaging (MRI), which not only show the enlarged ventricles, but also indicates the sites of obstruction. The images are usually normal in IIH, but that in itself is important information.
