Infected dermoid tumor causing tethered cord after myelomeningocele repair.

Intramedulary dermoid tumors are rare tumors mostly found associated with dermal sinus tracts. Spinal dermoid tumor can occur after myelomeningocele repair. Infected dermoid tumors are reported in patients with dermal sinus tracts as well, but have never been reported subsequent to myelomeningocele surgery. Here, we report a rare association of infected dermoid tumor with tethered cord without dermal sinus tract in a child who had been operated for myelomeningocele during infancy.
