Haemangioblastoma brain tumour. Magnetic resonance imaging (MRI) scan of a sagittal (side) section through the head of a 78 year old woman showing a haemangioblastoma. The tumour is seen as a round grey mass to the immediate right of the pons, a protrusion of nerve fibres (dark) at the top of the spinal cord. The tumour is partly cystic (fluid-filled) and is affecting the left lobe of the cerebellum. Haemangioblastomas are formed from cells that line the blood vessels, are almost always benign and are usually found in the cerebellum, the area at the back of the brain that controls coordination and balance. The main symptoms, such as headaches and sight problems, arise from increased pressure within the skull. Surgery is often the main form of treatment.
