Four distinct dysraphic anomalies were observed in a single child. While combinations of such anomalies are well recognised, quadruple dysraphic pathology, nevertheless, is extremely uncommon. To our knowledge, no previous cases have been reported in the literature. ⋯ Existing embryologic hypotheses for the dysraphic spectrum lack experimental evidence and studies in animal models. This case challenges the existing hypotheses and illustrates our incomplete understanding of human terminal spinal cord embryogenesis. Further studies on the morphogenetic basis for these anomalies are required.
