A lady aged 28
presented with low backache for 2 years. The pain radiated to both her legs and
had increased in intensity for the past 1 year.
She had a skin
dimple over her lower back which had been present since birth.
MRI of the spine
revealed a fibrous band attached to the skin of the back which then coursed through
the spinal cord and was attached to the cord’s coverings at its front. The
spinal cord was tethered and low lying, ending 3 vertebral levels below normal.
A diagnosis of
Limited Dorsal Spinal Rachischisis was made.
The dermal sinus
was excised and the cord de-tethered by microsurgical technique.
