NONCONTRAST MRI OF THE LUMBAR SPINE: 10/26/2010
COMPARISON:
None.
REASON FOR EXAM:
EVALUATE FOR CHRONIC LOW BACK PAIN.
CLINICAL HISTORY:
A 25-year-old old female with chronic lower back pain.
MRI PROCEDURE:
Using a 1.5 Tesla imager, the following pulse sequences were obtained;
sagittal T1 spin-echo, sagittal T2 SPIR, sagittal T2 spin-echo, axial T1
turbo spin-echo, and axial T2 spin-echo.

READ:
The lumbar spine demonstrates normal alignment. The desiccation of the
intervertebral disks at L3-4 and L4-5 manifests in the low signal as a
nuclei pulposi on T2 weighted sequences. Mild loss of disk height is also
seen at these levels.
Linear high signal within the posterior annulus fibrosis at L3-4 and L4-5
suggests annular tears.
An ovoid T2 hyperintense cyst within the central canal at the level of S2
measures 1.4 x 0.9 cm and is compatible with perineural cyst.
The vertebral bodies and remainder of the intervertebral disks exhibits
normal size, shape, and signal intensity. The distal thoracic spinal cord
and conus medullaris are normal in configuration and signal with the conus
identified at the L1 level. No paravertebral soft tissue mass is
identified.
Evaluation of the L1-2 level demonstrates no evidence of central canal or
neuroforaminal stenosis. No obvious disk protrusion or extrusion is
identified.
Evaluation of the L2-3 level demonstrates no evidence of central canal or
neuroforaminal stenosis. No obvious disc protrusion or extrusion is
identified.
Evaluation of the L3-4 level demonstrates a 5 mm diffuse disk bulge with
mild central canal stenosis and mild bilateral neuroforaminal stenosis. No
obvious disk protrusion or extrusion is identified.
Evaluation of the L4-5 level demonstrates a 5 mm diffuse disk bulge with
mild central canal stenosis and mild bilateral neuroforaminal stenosis. No
obvious disk protrusion or extrusion is identified.
Evaluation of the L5-S1 level demonstrates a 5 mm diffuse disk bulge with
mild right neuroforaminal stenosis, but no evidence of central canal or left
neuroforaminal stenosis.

MRI IMPRESSION:
1. MILD DEGENERATIVE DISK DISEASE, MOST PROMINENTLY AT L3-4 AND L4-5.
2. ANNULAR TEARS AT L3-4 AND L4-5.
3. PERINEURAL CYST IN THE SACRAL CENTRAL CANAL.
