What is mid-line shift and what does it mean? There was some mid-line shift even after my mom's surgery of stage IV GBM.

Hi Angie. You know that the brain is divided into two halves or hemisphere's... the left hemisphere and the right hemisphere. Between the two halves there is a valley that is called the "mid-line". Usually, as seen in an MRI, it looks like a straight line down the middle of the brain. If the tumor is large enough, it pushes that mid-line into the opposite side of the brain and the "line" no longer looks straight. That is called a "mid-line shift". It is not a good sign because it is a sign of a rather large tumor.
