Spontaneous clinical and radiological resolution of a large extruded disc in the lumbar spine

Low back ache arising due to a herniated lumbar disk with radicular pain to the lower limbs is a commonly occurring problem evaluated by spine surgeons. Conservative treatment has usually been proposed for an acute disk prolapse in cases without significant motor or sensory deficit. Spontaneous radiological regression of an extruded herniated disk with complete symptomatic recovery has occasionally been reported. A case of conservatively treated large extruded lumbar disk is described who showed complete radiological resolution, along with regression of the clinical symptoms.
