Spectrum of magnetic resonance imaging findings in congenital lumbar spinal stenosis

Figure 1 Mid-sagittal T2-weighted (3230, 120) image of the lumbar spine in a 50-year-old male with congenital lumbar spinal stenosis. The lumbar spine shows loss of the lordotic curve, multilevel spondylolisthesis, and degenerative disc disease manifested as loss of disc height, circumferential disc bugles, anterior disc herniations, Schmorl’s modes and a central disc protrusion. In this subject, the mid-sagittal spinal canal diameter ranged from 1.45 cm at the L1 level to 1.03 cm at L4 level. The average mid-spinal canal diameter was 1.26 cm.
