In brief: Big difference

Disc Protrusion is when the distance between the edges of the disc herniation is less than the distance between the edges of the base.
Disc Extrusion is when the distance between the edges of the disc material is greater than the distance at the base. Disc herniation may vary in severity from case to case.
