I believe TBI refers to the actual injury, while PCS refers to the after effects of the injury (dizziness, memory loss, irritability, etc).
You can have TBI without getting longstanding PCS symptoms, and (depending on your doctor's opinion of "mild" concussions) you can have PCS without ever having TBI. Most common combination is TBI with at least a few days of PCS symptoms, though.
