Dermoid cysts are congenital cystic tumors arising from embryonic rests and commonest site is in the thoracic region of the spinal canal. The authors reported a case of dermoid cyst in a 17-year-old boy appearing after lumbar meningomyelocele repair at 2 months of age.

Preoperatively small extradurally protruding placode was seen attached to the swelling. The swelling was completely excised.
