Evaluate for tether cord, syrinx, Chiari malformation: scoliosis, back pain, and headaches. There are postoperative findings in the thoracic spine related to removal of posterior spinal instrumentation. There is a thoracolumbar dextroscoliosis. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. The spinal cord is low lying, with the conus medullaris extending to the level of the L3 vertebra. The spinal cord signal otherwise appears to be normal. However, there appears to be thin linear T2 hyperintensity in the region of the filum terminale. The cerebellar tonsils are not low-lying.
1. Thoracolumbar dextroscoliosis and low-lying conus medullaris, which may represent tethered cord and possible small fibrolipoma of the filum terminale.2. No evidence of Chiari I malformation.
