Primary CNS lymphoma
Primary CNS lymphoma is a non-Hodgkin (typically B-cell) lymphoma that arises within, and generally remains confined to, the nervous system. It usually occurs in the brain as an intracranial mass (masses) but may also involve the spinal cord parenchyma, leptomeninges, and eyes. The overwhelming majority of patients presents with symptoms and signs suggestive of a brain tumor.
