Male, 72 years old, with positive Hoffman sign, assess for spinal stenosis. Sagittal alignment is within normal limits. Vertebral body height and morphology are unremarkable. No concerning marrow replacement or marrow edema is seen.The visualized spinal cord demonstrates normal signal intensity and morphology except as discussed below. No pathologic epidural process is suspected.C2-3: Severe right and moderate left facet hypertrophy. Ligamentum flavum thickening. No significant spinal canal stenosis. Moderate right foraminal narrowing. No interval changes.C3-4: Moderate bilateral facet hypertrophy. Minimal posterior disc-osteophyte complex formation. Ligamentum flavum thickening. No significant spinal canal stenosis. Severe left and moderate right foraminal narrowing. No interval changes. C4-5: Moderate bilateral facet hypertrophy. Ligamentum flavum thickening. Posterior disc-osteophyte complex formation particularly in the left paracentral region with mild flattening of the ventral cord, not significantly changed from prior. Severe right and moderate left foraminal narrowing, unchanged. C5-6: Bilateral facet hypertrophy. Posterior disc-osteophyte complex formation with a superimposed central disc protrusion which is mildly larger than on the prior exam. This causes mild flattening of the ventral spinal cord and a mild to moderate generalized spinal canal stenosis, progressed from prior. Moderate bilateral foraminal narrowing, unchanged.C6-7: Facet hypertrophy. Minimal posterior disc-osteophyte complex formation with right uncovertebral hypertrophy. No significant spinal canal stenosis. Moderate to severe right foraminal narrowing. No interval changes.C7-T1: Facet hypertrophy. Very small right paracentral disc protrusion. No significant spinal canal or foraminal stenosis. No interval changes.
1.Posterior disc-osteophyte complex formation with a central disc protrusion at C5-6 appears to be mildly increased from the prior exam. This results in a progressive mild to moderate generalized spinal canal stenosis with mass effect on the ventral spinal cord but no cord edema.2.Posterior disc-osteophyte complex formation at C4-5 with mild mass effect on the ventral spinal cord is unchanged from prior.3.Scattered foraminal narrowing shows no significant interval change with the most significant stenoses on the left at C3-4, on the right at C4-5, and on the right at C6-7.
