ABSTRACT

One case of far lateral lumbar disc herniation(FLLDH) at left L5-S1 intervertebral space is reported. The herniation of disc material was localized mainly beyond the intervertebral foramen. Metrizamide myelogram was normal and only spine CT scan revealed the protruded disc material compressing the upper root inside and outside of the intervertebral foramen. Accordingly, the presenting symptoms and signs were due to left L5 root compression. Facetectomy was followed by removal of the herniated disc material. The patient was improved well.
