Sonographic demonstration of lumbar disc herniation.

In a limited series of examinations the capability of ultrasonography in the assessment of intervertebral disc herniation by a transabdominal approach is evaluated. Normal anatomical findings on transabdominal spinal sonography are demonstrated. Two cases of disc herniation proved either by operation or lumbar myelography and spinal computed tomography are reported. The potential capabilities and known limitations of ultrasonography in this field are discussed.
