The conus ends abnormally low at the level of L3. The filum is thickened and fatty (particularly at the S2 level). Better seen on the previously obtained CT of the lumbar spine the sacrum demonstrate unfused posterior elements consistent with spina bifida. No evidence of meningocoele or lipomeningocoele, although some soft tissue stranding in the midline is present.
Conclusion: No evidence of neural foraminal compromise or spinal stenosis. No paraspinal enhancing masses or evidence of discitis or osteomyelitis. Spina bifida and tethered cord.
