Indication: Numbness of legs



Technique: MRI lumbar spine with sagittal and axial T1 and T2
weighted images, postcontrast sagittal and axial T1-weighted images.



Contrast: 11 mL Multihance IV.



Findings: Alignment is near-anatomic. Vertebral body and disk
heights relatively preserved. No suspicious focal T1 dark marrow
lesions. Small Schmorl's nodes are noted at some levels for example
superior endplate L3. No significant compromise of the canal or
neural foramina at any level. Distal cord and conus is within normal
limits position T12/L1 and roots of cauda equina appear within normal
limits.



Probable nerve root sheath cyst noted along the extraforaminal S1
nerve root and to a lesser extent S2 nerve roots more proximal, not
uncommonly seen.



No abnormal enhancement cord, cauda equina, or coverings.



Impression: Unremarkable MRI lumbar spine except for probable nerve
root sheath cysts associated with right S1 greater than S2 nerve
roots, not uncommonly seen. No explanation for bilateral lower
extremity numbness.
