Pineal Tumors
Pineal Tumors 3.7.1 Pineoblastoma Pineoblastomas belong to the group of PNETs, placing them in the same category as medulloblastomas and ependymoblastomas. Pineoblastomas occur mainly in very young patients. They are aggressive…
Degenerative Spinal and Foraminal Stenoses
Thus, imaging results can be accurately interpreted only within the context of a detailed history and clinical examination. Of course, this principle applies to all radiologic findings. Degenerative changes in…
Astrocytic Tumors
Astrocytic Tumors Many primary tumors of the central nervous system (CNS) arise from glial cells. The glial cells, in turn, are comprised of astrocytes, oligodendrocytes, and ependymal cells. Astrocytes give…
Malformations and Developmental Abnormalities
To understand malformations of the brain, the reader should be familiar with the critical processes that occur during embryonic development. This chapter focuses on the developmental processes that are essential…
