This is to report two cases of cervical disc herniation in which their neurological signs were recognised mainly in the lower limbs, showing similar symptoms to thoracic myelopathy.Case I is a 40 year-old female, and Case II is a 50 year-old male. They felt numbness of the right lower limb at onset, which gradually increased and was accompanied by motor disturbance of the left lower limb. Deep tendon reflex of the lower limbs was hyperactive in both cases. Sensory disturbance was noticed below the level of Th6 in case I and below the level of Th4 in case II. No symptoms and signs in the upper limbs except positive Hoffman's reflex in the left hand were recognised. X-ray showed slight narrowing of the disc space at C5-C6. Myelograms demonstrated a filling defect of contrast medium around the level of C5-C6.Surgical exploration through anterior approach confirmed cervical disc herniation, and good results were obtained after the surgery.
