What best describes a midline shift?

Explanation:
Midline shift happens when a mass effect from a lesion on one side of the brain pushes brain tissue across the brain’s midline into the opposite hemisphere. That crossing of the midline is the defining sign, so describing it as the brain being pushed toward the other side captures the core idea. This shift signals significant intracranial pressure and potential herniation risk, which is why it’s a critical imaging finding. Unilateral swelling or rotation describes other aspects of injury but doesn’t specifically convey the cross-midline displacement that defines a midline shift.
