Throughout the book, emphasis has been placed on histopathologic characteristics and differential diagnosis, which are summarized in tables to make the explanation of certain topics clearer. This valuable text also includes the most recent clinical, pathological, histological, cytological, and molecular knowledge in the field, enabling pathologists to arrive at the correct diagnosis and prepare actionable, useful reports. Since pathology is one of the most visually oriented medical specialties, the myriad of annotated images throughout has been evaluated carefully and include neuroimaging studies, histology, cytology, and immunohistochemical stains that support a morphologic discussion in which differential diagnosis and potential pitfalls are emphasized. Central Nervous System Tumors: Diagnostic Pathology provides a comprehensive guide of the current critical information needed to recognize, understand, and interpret this demanding field of surgical neuropathology.
