Male, 25 years old, with new back pain radiating to the leg, status post laminectomy in July 2015. Findings are again seen compatible with right sided laminectomy and facetectomy at L2-3. Since the prior examination, acute postoperative fluid and edema have resolved. No new or concerning fluid collection is seen.At the L2-3 level, evidence of disc degeneration persists with loss of disc height and disc T2 signal as well as a generalized bulge of the disc with a superimposed small central protrusion. These findings are unchanged when compared to the prior examination. However, with resolution of postoperative edema, the degree of spinal canal narrowing at this level has improved. The right foramen at this level is only mildly narrowed.At L4-5, mild loss of disc height and T2 signal is seen along with a small central disc protrusion. There is no significant generalized spinal canal or neuroforaminal stenosis.The remaining levels show normal disc morphology, with patency of the spinal canal and neural foramina. Mild facet hypertrophy at lower lumbar levels is unchanged.Spinal alignment is slightly straightened but otherwise unremarkable. Vertebral body heights are preserved. No worrisome marrow signal abnormality or marrow edema is seen.
1.Demonstration of findings related to right-sided laminectomy and facetectomy at L2-3. Since the prior examination, postoperative fluid and edema in the posterior soft tissues have resolved.2.Degenerative disc disease persists at L2-3 with a mild bulging disc with small central disc protrusion. With resolution of postoperative edema, however, the degree of spinal canal narrowing at this level is improved from the prior exam.3.A small central disc protrusion at L4-5 is unchanged without significant spinal canal or neuroforaminal narrowing.4.No additional or new findings are seen to account for the patient's symptoms.
