Cant see the neuro until Sept. any suggestions. [/INST] Hi, thanks for using Chat Doctor Vertigo can be due to central or peripheral causes. Central causes mean that the problem originates from the brain or spinal cord. The structures in the brain that are mainly involved in balance are the brain stem and the cerebellum. The lesion or spot that was seen on the MRI can be due to different possible conditions such as : (1) artifact- this is something that is not actually present within a person but due for example to the machine used or tool(2)a mass within the brain stem- it is possible that it is related to a tumor(3) stroke-this is due to disrupted blood supply to an area of the brain, it would also cause a change in the image(4)infection(5)trauma(6) multiple sclerosisYOur neurologist would be able to determine, based on physical findings and reviewing the image, what the area represents. I wish you the best and hope this helps </s>
