Introduction The understanding of low-grade gliomas has significantly changed over the past 10 years. Genomic and epigenetic discoveries have revolutionized our understanding of these cancers. For the first time, the…
Introduction Meningiomas are slow-growing extraaxial tumors that account for about 25% of all intracranial tumors. The World Health Organization (WHO) classifies meningiomas as grade I, II, or III based upon…
Disclosures Dr. Ly has no disclosures. Dr. Jordan has research funding from the Department of Defense, the National Institutes of Health, and the Burke Foundation. He receives royalties from Elsevier…
Introduction There is significant overlap in the imaging appearance and presentation of dural-based mass lesions. The differential diagnosis includes both benign lesions (such as meningioma—WHO grade I) and more aggressive,…
Introduction Spinal cord tumors are uncommon causes of back pain, radicular pain, and sensorimotor deficits in adults and pediatric patients. Primary spinal tumors are less common than intracranial tumors and…
Introduction The posterior fossa is the infratentorial compartment of the cranial vault, which houses the cerebellum and the bulk of the brainstem. Tumors that occur in this region can arise…
Introduction Central nervous system (CNS) tumors encompass histologically diverse entities with widely varying prognostic and therapeutic implications. Within the brain, tumors can be divided into two main categories: primary and…
Introduction Chemotherapy has a crucial role in the management of gliomas. Traditionally, the management is characterized by an extensive surgery followed by a combination of radiotherapy (RT) and chemotherapy. In…
Background: radiation biology and physics overview Radiation therapy treats cancer by causing DNA damage, most importantly double-strand breaks (DSBs). Although normal cells can efficiently detect and repair DSBs through homologous…
Introduction In typical cases, the clinical workflow for brain tumors begins with imaging studies; however, despite the increased sensitivity and capabilities of these methodologies, diagnosing brain tumors requires histopathologic evaluation…
