 The lumbar spine is in normal alignment, with slight straightening of the normal lumbar lordosis. The vertebral body and disk heights are well-maintained. No worrisome focal marrow signal abnormality is appreciated, although there is slight indentation of the superior and inferior endplates of the anterior L1 vertebral body, likely a developmental finding. Trace linear T2 signal is present within the distal central cord, which may represent a terminal ventricle.The distal spinal cord and conus are within normal limits with the conus terminating at the mid L1 level. No abnormal fat signal is seen within the distal thecal sac. No definite spinal dysraphism is appreciated on MRI, although CT would be more subtle. Upon prone positioning, there is appropriate ventral motion of the distal conus as well as cauda equina nerve roots within the thecal sac.There is no significant disk bulge, herniation, spinal canal or foraminal stenosis within the lumbar spine.Bladder is significantly distended.
Likely mild developmental irregularity of the anterior L1 vertebral body along the superior and inferior endplate. Otherwise, unremarkable noncontrast MR appearance of the lumbar spine. Significant bladder distention for which clinical correlation is recommended.
