Reason: syrinx spine, yearly follow up History: yearly follow up. Untethered 2/2009. There are again extensive multi-level segmentation anomalies involving virtually the entire spine and rotatory scoliosis with thoracic curve to the left. There is a stable low-lying conus, which is again at the L3 vertebral level. No prone imaging was performed. There is a persistent syrinx most conspicuous in the lower thoracic cord, which measures 6 x 8 mm in greatest axial dimensions. There is also a stable thickened filum measuring up to 3 x 4 mm along the distal thecal sac, although discontinuous, consistent with prior untethering surgery.There is no significant spinal canal stenosis. Marrow signal is unremarkable. Sagittal alignment is unremarkable.
1. Stable syrinx most prominent in the lower thoracic cord.2. Low-lying conus medullaris remains at L3 level. Prone imaging not available. 3. Extensive multi-level segmentation anomalies and scoliosis.
