Low back pain and leg numbness. Leukocytosis. Rule out epidural abscess. There are 5 lumbar-type, ribless vertebrae. The last well-formed disc is at L5-S1.Alignment is anatomic. The vertebral bodies are preserved in height. The intervertebral discs are preserved in height and T2 signal. There is no significant marrow signal abnormality. The spinal canal is preserved. The tip of the conus medullaris lies at mid L1 vertebral level. The conus medullaris shows normal shape and signal characteristics. Following contrast injection, there is no abnormal spinal cord, leptomeningeal, epidural or osseous contrast enhancement. Stranding, T2-hyperintensity and contrast enhancement in the subcutaneous fat at L3 and L4 levels is very nonspecific and may reflect dependent edema.The paraspinal soft tissues are notable for a 6 mm, well-circumscribed, T2-hyperintense, T1-hypointense, noncontrast enhancing lesion arising from the inferior pole of the right kidney which is probably a cyst.
1.No sign of lumbar spinal infection.2.No significant degenerative disease of the lumbar spine.
