Anatomic Variations



Several important steps occur in order for the sacrum to develop properly. Embryological derailment can result in several different anatomical variants.

Case report

Herein, we report, to our knowledge, the first case of a duplicated sacrum in the sagittal plane.


Clinicians and radiologists should be aware of such a finding if found during imaging. We would hypothesize that such a variant occurred near the 29th day of development and probably arose from an error in the HOX gene. To our knowledge, this represents the first reported case.
