A Primer on Secondary Brain Neoplasms: The Essentials

Secondary intracranial brain neoplasms are defined as intra- and extra-axial lesions metastasizing from tumors outside the central nervous system (CNS). Secondary intracranial brain neoplasms are much more common than primary tumors, with rates ranging from 100,000-260,000 cases per year in the United States.1 According to the 2009-2013 Central Brain Tumor Registry of the United States, the overall incidence rate of all primary malignant and nonmalignant brain and other CNS tumors is an estimated 79,270 new cases expected in 2017 or 22.36 cases per 100,000/year (7.18 malignant and 15.18 for nonmalignant tumors).
