We describe a unique series of 3 cases of biliary atresia (BA) associated with a choledochal cyst. All 3 children presented with jaundice at birth and had no other abnormalities. Although these children had a fetal form of BA, their presentation and outcome differed from those of biliary atresia splenic malformation syndrome (BASM), the well-described form of early onset BA. Unlike those with BASM, these children had no other associated malformations, had a normal birth weight, and did not yet require a liver transplant. We believe that the present series of patients and their associated pathology may represent a distinct phenotype with a common, prenatally acquired etiology that is different from other fetal forms of BA, such as BASM, and from patients who present with the classic perinatal form of BA.
