Primary Central Nervous System Lymphoma

Primary central nervous system lymphoma is a rare cancer of the lymphatic system that starts in the brain, spinal cord, eyes or the membranes around them, without spreading from elsewhere in the body. It can cause confusion, weakness, headaches or vision problems. Treatment usually begins with high-dose methotrexate-based chemotherapy, sometimes followed by other therapies.
