Female, 72 years old, with right-sided lumbar back pain. A mild scoliotic curvature of the thoracic lumbar spine is seen. Alignment is otherwise unremarkable. Vertebral body height and morphology are normal.Hemangiomas are present within the T10 and L1 vertebral bodies. There may be mild fatty degenerative signal abnormality along the superior L4 endplate. Note is made, however, of STIR hyperintense signal within the right L4 pedicle (see image 17 series 4) compatible with edema. This is seen in the context of marked facet arthropathy at L4-5.The visualized spinal cord and conus are unremarkable. Additional details pertaining to the spinal canal are as follows:T12-L1: L1-2: Facet hypertrophy with small effusions. No significant spinal canal stenosis. Moderate left and mild right foraminal narrowing. L2-3: Facet hypertrophy and ligamentum flavum thickening. No significant spinal canal stenosis. Mild left foraminal narrowing.L3-4: Facet hypertrophy, worse on the left, and ligamentum flavum thickening. Mild bulging disc. Mild generalized spinal canal stenosis. Severe left and moderate right foraminal narrowing. L4-5: Marked bilateral facet hypertrophy. Ligamentum flavum thickening. Mild bulging disc. Mild generalized spinal canal stenosis. Severe right and moderate left foraminal narrowing. L5-S1: Marked bilateral facet hypertrophy. Mild bulging disc. No significant generalized spinal canal stenosis. Moderate bilateral foraminal narrowing.
1.Marked facet arthropathy is evident at L4-5. Edema within the right L4 pedicle may be reactive to this arthropathy.2.Moderate to severe posterior element hypertrophy is seen at additional levels as above.3.Relatively mild degenerative disc disease is seen without evidence of high-grade spinal canal stenosis.
