MRI documentation of Spontaneous Regression of lumbar disc herniation- A case report.

Spontaneous regression of a herniated nucleus pulposus (HNP) occurs where intervertebral disc herniation loses its volume partly or totally without surgical interventions. In 1985, Teplick and Haskin first documented the spontaneous resolution of lumbar disc by computerized tomography and they reported that 9 out of their 55 patients harboring lumbar disc herniation showed spontaneous regression. The gold standard modality for visualizing the herniated disc is MRI these days. The following case reports the MRI documentation of spontaneous disappearance of acute lumbar disc extrusion in a patient treated conservatively.
