Disappearing Intervertebral Disc Herniation
Spontaneous regression of herniated nucleus pulposus occurs when intervertebral disc herniation loses its volume partly or totally without surgical interventions. Cases of spontaneous regression of large extruded lumbar disc are rare. We presented a patient with large lumbar disc extrusion documented by Magnetic Resonance Imaging, but not found intraoperatively four months after performing diagnostic. Postoperatively he felt well for two months when the pain reappeared. Control Magnetic Resonance of lumbar spine showed complete resolution of extruded disc fragment comparing with the initial Magnetic Resonance Imaging.
