Regression of lumbar disc herniation with non-surgical treatment: a case report.

To date, only a few reports have described the regression of lumbar disc herniation, which may be because of a failure to follow up patients treated conservatively. We report a case of a 25-year-old man who presented with a 2-month history of pain and soreness owing to lumbar disc herniation. He was managed conservatively, and his presenting symptoms and scoliosis gradually decreased over approximately 5 months. Two years later, he returned unexpectedly and was advised to undergo magnetic resonance imaging, which revealed regression of the disc herniation; the patient also confirmed that the pain had not recurred. After 8 months, he underwent repeat magnetic resonance imaging, and the findings pertaining to disc herniation were normal. Our findings suggest that previous cases should be retrospectively studied to establish a prediction model for the outcomes of conservative treatment in patients with lumbar disc herniation. We also emphasize the significance of selecting suitable patients for conservative treatment to obtain the best therapeutic outcomes. The CARE guidelines have been followed in the reporting of this case.
