61-year-old female with recurrent left thigh pain and back pain, history of L4/5 left foraminal herniation Redemonstrated is mild generalized narrowing of the spinal canal which is believed to be at least partially secondary to congenital anatomical variation of the short pedicles. A left simple renal cyst is stable.T10/11 demonstrates bilateral ligamentum flavum hypertrophy which results in mild bilateral neural foraminal stenosis.T11/12 demonstrates significant asymmetric left-sided ligamentum flavum hypertrophy which results in mass-effect and forward displacement of the cord and central spinal stenosis. Moderate to significant right neural foraminal compromise is also detected. These findings are unchanged. Previously demonstrated mild increased T2 signal intensity of the cord is not well demonstrated on the current exam given the lack of axial T2 imaging.T12/L1 demonstrates asymmetric right-sided ligamentum flavum hypertrophy and mild bilateral facet disease. There is significant right neural foraminal compromise, no central spinal stenosis and patent the left neural foramina. These findings are unchanged.L1/2 demonstrates moderate bilateral (right greater than left) ligamentum flavum hypertrophy and mild right facet hypertrophy. There is significant right neural foraminal compromise, no central spinal stenosis and patent the left neural foramina. These findings are unchanged.L2/3 demonstrates mild disk disease and loss of disk height, mild left and moderate right facet and ligamentum flavum hypertrophy. There is a linear T2 hyperintensity in the annulus of the disk laterally on the left consistent with an annular fissure. There is moderate bilateral neural foraminal compromise. These findings are unchanged. Secondary to slight increase in posteriorly located epidural fat, there is now moderate central stenosis (previously mild to moderate). L3/4 demonstrates mild disk disease and loss of disk height, moderate bilateral ligamentum flavum hypertrophy, mild degenerative facet disease and evidence of bilateral facet effusion. There is mild to moderate bilateral neural foramina compromise. These findings are unchanged. Secondary to increasing posteriorly located epidural fat, there is now moderate central spinal stenosis (previously mild).L4/5 demonstrates postoperative changes with resection of a left foraminal/lateral disc herniation. Enhancement is noted within the operative approach, surrounding the L4 nerve roots, however without associated mass effect. Redemonstrated is mild degenerative disk disease and loss of disk height, mild to moderate bilateral facet and ligamentum flavum hypertrophy. Moderate left neural foraminal and moderate to severe right neural foraminal stenosis are unchanged. Secondary to increasing posteriorly located epidural fat, there is now mild central stenosis (previously no stenosis).L5/S1 demonstrates mild disc disease and loss of disk height, moderate bilateral facet hypertrophy and mild ligamentum flavum. No central spinal stenosis. Moderate (left greater than right) neural foraminal compromise is present. These findings are unchanged.Unremarkable paraspinal soft tissues other than above mentioned left renal cyst.
1.T10/11: mild bilateral neural foraminal stenosis.2.T11/12: Moderate to significant right neural foraminal compromise and central stenosis is unchanged. Previously demonstrated mild increased T2 signal intensity of the cord is not well demonstrated on the current exam given the lack of axial T2 imaging.3.T12/L1: Right neural foraminal compromise is unchanged.4.L1/2: Right neural foraminal compromise is unchanged.5.L2/3: Moderate bilateral neural foraminal compromise is unchanged. Secondary to slight increase in posteriorly located epidural fat, there is now moderate central stenosis (previously mild to moderate). 6.L3/4: Mild to moderate bilateral neural foramina compromise is unchanged. Secondary to increasing posteriorly located epidural fat, there is now moderate central spinal stenosis (previously mild).7.L4/5: Postoperative changes with resection of a left foraminal/lateral disc herniation. Enhancement is noted within the operative approach, surrounding the L4 nerve roots, however without associated mass effect. Redemonstrated is moderate left neural foraminal and moderate to severe right neural foraminal stenosis, unchanged. Secondary to increasing posteriorly located epidural fat, there is now mild central stenosis (previously no stenosis).8.L5/S1: Moderate (left greater than right) neural foraminal compromise is unchanged.
