The authors report a case of tethered cord syndrome preceding the developme
nt of a syrinx, which subsequently resolved with detethering. This was show
n conclusively with serial radiological imaging, although the patient did n
ot 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 de
tethering should therefore be the aim in patients with tethered cord syndro
me.
