Tethered cord syndrome preceding syrinx formation--serial radiological documentation

The authors report a case of tethered cord syndrome preceding the development of a syrinx, which subsequently resolved with detethering. This was shown conclusively with serial radiological imaging, although the patient did not improve clinically. The lack of clinical improvement is likely to be due to the delay in surgery caused by infections in this patient, and early detethering should therefore be the aim in patients with tethered cord syndrome.
