At the L5/S1 disc space level, disc herniation is noted deforming the anterior epidural fat and the anterior margin of the thecal sac abutting the proximal S1 nerve roots bilaterally. Bilateral proximal neural foraminal extension is noted abutting the exiting L5 nerve roots. Signal elevation is noted within the posterior margin of the annulus fibrosus suggestive of annular fissure. Bilateral facet hypertrophic changes are noted. Loss of disc signal is noted with preservation of disc space height with anterior disc extension.
At L4/5, there is no evidence of herniated disc, spinal canal compromise, neural foraminal stenosis, lateral recess encroachment or loss of disc space height or signal. Bilateral facet hypertrophic changes are noted.
At L3/4, there is no evidence of herniated disc, spinal canal compromise, neural foraminal stenosis, lateral recess encroachment or loss of disc space height or signal. Anterior disc extension is noted.
At L2/3, there is no evidence of herniated disc, spinal canal compromise, neural foraminal stenosis, lateral recess encroachment or loss of disc space height or signal. Anterior disc extension is noted.
At L1/2, , there is no evidence of herniated disc, spinal canal compromise, neural foraminal stenosis, lateral recess encroachment or loss of disc space height or signal.
At T12/L1 , there is no evidence of herniated disc, spinal canal compromise, neural foraminal stenosis, lateral recess encroachment or loss of disc space height or signal.
There is only limited assessment provided of the T11/12 and T10/11 disc spaces at the peripheral margin of the included field of view on the sagittal sequences. There is no evidence of herniated disc, spinal canal compromise, neural foraminal stenosis, or loss of disc space height or signal suggested at either level.
Lumbar spine straightening is noted, a nonspecific finding which meets the criteria for muscle spasm. Dextroscoliosis is noted. Hemangiomata are incidentally noted within the L4 and T12 vertebral bodies.
There is no evidence of lumbar vertebral body compression fracture. There is no evidence of bone marrow infiltrative disorder. There is no evidence of spondylolisthesis.
There is no evidence of signal abnormality within the conus medullaris which is located at the approximate T12/L1 disc space level.
There is only limited assessment provided of abdominal structures. Approximate 9 mm left renal cyst is suggested not identified on prior exam. This may be related to small size of the suggested cyst in conjunction with volume averaging and plane of section.
Examination is compared to previous MRI study of the lumbar spine dated 9/24/2017. There is no significant interval change demonstrate.
