Fully developed accessory lower limb with tethered cord: Are these two anomalies related?

Background Spinal dysraphic anomalies may be hidden beneath grotesque cutaneous stigmata, like a fully developed accessory lower limb. Case description Authors describe a 4-year-old boy who had socially unacceptable malformation in form of an accessory lower limb, in addition to perfectly normal both lower limbs with underlying low-lying tethered cord. Radiological studies showed underlying tethered cord and dysraphic spinal column. Conclusion Successful surgical correction was undertaken along with detethering of cord. The present case asks for evaluation of all cutaneous stigmata over spinal regions in newborns for spinal dysraphic states.
