Lymphoma, Primary CNS (PCNSL)
A rare disease of the white blood cells known as B-lymphocytes which are normally found in lymph nodes, blood, and throughout the body. Primary CNS lymphoma occurs when lymphoma cells form in the tissue in the brain, eye, or spinal cord and is not present anywhere else in the body.
Known causes of primary CNS lymphoma include infections such as HIV and Epstein-Barr, while some causes are still unknown. The effectiveness of the treatment may depend upon the stage and extent of the disease at diagnosis and if an HIV infection is also present.
