Reason: Syrinx and tethered cord, status post repair, yearly follow up for changes , please do with tethered cord protocol History: yearly follow up Again seen is prominence of the central canal in the distal cervical and upper thoracic cord. More discrete dilatation with T1 hypointensity consistent with syringohydromyelia begins at approximately the T7 level and continues inferiorly to the T12 levelnear the conus. The craniocaudal extent of this abnormality is unchanged. Likewise, the maximal caliber of the syrinx is also not significantly changed, for example measuring 5 x 6 mm at the T9-T10 level, previously also 5 x 6 cm.Cervical tonsils are again imaged only on the sagittal counting sequence and appear low-lying but without clear evidence of Chiari I. Dedicated brain imaging can be considered as clinically appropriate.The conus tip terminates at the L1 level which is normal. Findings are again seen compatible with surgical tethered cord release at the L2-3 level. No evidence of fatty infiltration of the filum terminale, lipoma, or other lesions within the lumbar spinal canal. On prone imaging, there is appropriate anterior motion of the conus and cauda equina. Spinal alignment is anatomic. Vertebral body heights and disc spaces are maintained. No significant spinal canal or foraminal stenosis is present at any level. As on the prior examination, the urinary bladder is fluid distended. There is atelectasis in the right lower lobe.
1.No significant change in syringohydromyelia involving the mid to lower thoracic cord.2.No evidence of spinal cord re-tethering.
