title: The Ventricular System of the Brain: Anatomy and Normal Variations.
abstract: The cerebral ventricular system is intimately associated with the forebrain and brainstem. The ventricular system functions to produce and circulate cerebrospinal fluid, which plays an important role in mechanical protection and regulation of homeostasis in the central nervous system. This article discusses anatomy and neuroimaging of the ventricular system and highlights normal anatomical variations that may be mistaken for pathology. Applied surgical anatomy is reviewed with emphasis on operative approach and potential risk to adjacent central nervous system structures.
