Introduction: Dorsal cutaneous appendages, sometimes referred to as "human tails," are considered to be markers of underlying occult spinal dysraphism. Rarely, these tail-like structures can themselves be the cause of tethered cord syndrome. However, to date, a "bony human tail" causing tethered cord has not been reported in the literature. One such rare lesion is being reported. Discussion: A 2-days-old female child was brought for neurosurgical consultation with a skin-covered bony protuberance in the lower back. Examination of the child did not reveal any neurological deficits. Plain radiographic and CT evaluation showed a dorsal bony protuberance arising from the posterior elements of L1 vertebra. MRI showed the cord to be displaced posteriorly and adherent to the undersurface of the bony tail through a lipoma. During surgery, the bony "tail" was excised, and the cord was untethered with excision of the lipoma, which was tethering the cord to the bony "tail." When examined 1 year later, the child was developing normally without any focal neurological deficits. Conclusions: This case is being reported for its rarity and to highlight the hitherto unreported occurrence of "bony human tail" causing tethered cord syndrome. © 2013 Springer-Verlag Berlin Heidelberg.
