Abstract

Several types of benign cysts occur in parenchymal, ventricular, or subarachnoid space locations throughout the cranial and spinal cavities. They can be classified according to their cell lining into epithelial-lining cysts (squamous and columnar-to-cuboidal) and nonepithelial-lining cysts (arachnoid membrane and astrocytic gliosis). Their differential diagnosis depends largely on their location, as well as on the lining cells (when intact) and cystic content. This chapter reviews the cytomorphologic features and differential diagnosis of these entities.
