Post operative scar around S1 nerve root

Case contributed by Dr Frank Gaillard
Modality: MRI

Case Discussion:

30M with a recent L5/S1 hemilaminectomy and discectomy with persistent left S1 nerve root symptoms.

Pre and post contrast MRI demonstrates the S1 nerve root to be enhanced by enhancing scar tissue.

This is a good demonstration of the need for contrast in the post operative spine to distinguish scar from recurrent disc.
