What is mass-effector midline shift is seen on brain mri mean?

Mass-effect midline shift on a brain MRI indicates that there is a significant displacement of the brain's midline structures, often due to increased intracranial pressure from a mass lesion such as a tumor, hemorrhage, or edema. This shift can compress brain tissue and disrupt normal function, potentially leading to serious neurological deficits. The degree of midline shift can help assess the severity of the underlying condition and guide treatment decisions.
