Case series of spondylocostal dysostosis and associated congenital malformations

Abstract

Spondylocostal dysostosis (SCD) is a rare anomaly of axial skeleton due to flawed embryological development characterized by malformed ribs, fused ribs, and hemivertebra. Case one: A newborn baby boy with right-sided polythelia, meningocele, fan-like configuration of 3 rd and 4 th rib, fused 5 th and 6 th rib, and 3 rd thoracic hemivertebra was delivered to a second gravid mother by elective cesarean section. Based on clinical examination and radiological picture, a diagnosis of SCD with meningocele with right-sided polythelia was made. Case two: Baby girl born to primigravida mother by cesarean section had hemivertebrae with multiple right-sided rib defects, short neck, preauricular ear tags, imperforate anus, and rectovaginal fistula. Very few cases of SCD have been reported in literature with neural tube defects (NTDs) with supernumerary nipple, none from developing country. Till now, there is limited literature regarding the associations of SCD none showing its association with the genitourinary system without NTDs. We need to study the causal associations of SCD with detailed genetic work up as it is not so uncommon as presumed.
