The disc regression correlated with clinical improvement documented by MRI studies. Although the phenomenon of spontaneous disappearance of decrease in size of herniated disc fragments is well known, the exact mechanism underlying this process remains unclear. We discuss 3 possible explanations for disc regression: retraction into the vertebral space, dehydration/shrinkage, and resorption due to inflammatory reaction.
