Exam: MRI Lumbar Spine W/o Contrast
History low back pain.
performed on a 1.5 Tesla magnet in sagittal and axial projection.
Prior examination, lumbar x-ray done 3/14/2017
FINDINGS: The lumbar
lordosis is well preserved. Disc margins
are well-preserved regarding height although there is some desiccation from
L3-L4 down to L5-S1. The conus
medullaris shows no evidence of abnormality.
Minimal posterior disc bulge T11-T12 without cord
contact. Foramina at this level as well
as thoracolumbar junction are widely patent bilaterally.
L1-L2 is unremarkable.
L2-L3 is unremarkable.
L3-L4 shows mild posterior disc bulge which may be a source
of discogenic pain. There is slight
effacement of the thecal sac. The left
and right foramina are widely patent but there is slight posterior displacement
of the left L4 nerve root in the lateral recess as seen on image 12/6. Facets are hypertrophic.
L4-L5 demonstrates moderate facet hypertrophy but bilateral
foraminal patency is preserved. No
lateral recess encroachment or spinal stenosis present.
Moderate facet hypertrophy L5-S1. Posterior disc herniation centrally and
slightly to the left, measuring about 8 mm in diameter.
hypertrophy from L3-L4 down to L5-S1 inclusive.
Slight disc protrusion L3-L4 with possible left L4 lateral recess
L4-L5 facet hypertrophy.
Some posterior disc protrusion which may be a source of discogenic pain.
L5-S1: Small central disc herniation confined by the
posterior longitudinal ligament, possibly source of discogenic pain. Facets are hypertrophic. No foraminal or spinal stenosis of the…
