Type 2 caudal regression syndrome

Abstract

Caudal regression syndrome (CRS), also known as caudal dysgenesis, consists of a constellation of caudal developmental anomalies along with soft-tissue anomalies. The severity of its spectrum ranges from lumbosacral agenesis to isolated absence of coccyx. The pathophysiology of the disease is not fully known due to its rarity. In this case report, we present a case study of CRS observed in a preadolescent school-aged male child. Our objective is to contribute to advancing the literature surrounding this exceedingly rare syndrome and contextualise our findings within the broader research landscape.
