Brain tumour. MRI (magnetic resonance imaging) scans. The front of the head is at right. The model is showing the internal structures of the right-hand side of the head, revealing the brain and spinal cord (white) and a large brain tumour (blue), a benign (non-cancerous) meningioma. Meningiomas are most often benign and arise from the meninges, the protective membranes that cover the brain and spinal cord. As it grows, a meningioma compresses adjacent brain tissue, and symptoms, such as headaches, are often related to this compression. Usually the tumour can be removed surgically, although radiotherapy may also be needed.
