Concern of tethered cord: sacral dimple. The conus medullaris is positioned at the T12 level and the imaged spinal cord and cauda equina nerve roots are unremarkable. There appears to be appropriate shifting of the spinal canal contents between prone and supine imaging. There is no evidence of fibrofatty filum. However, there is prominent epidural fat from L4 to the inferior sacral canal, with variable narrowing of the spinal canal. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. The spinal cord displays normal signal and morphology. The paravertebral soft tissues are unremarkable. The right kidney is absent.
1. No specific findings to suggest tethered cord or associated anomalies.2. Epidural lipomatosis from L4 to the inferior sacral canal.3. The right kidney is absent.
