Add to personal list- Summary
- We report the rare association of Caroli disease (intrahepatic bile duct ectasia associated with congenital hepatic fibrosis), bilateral cystic renal dysplasia, situs inversus, postaxial polydactyly, and preauricular fistulas in a female child. She presented with end-stage renal disease at the age of 1month, followed by a rapidly progressing hepatic fibrosis and dilatation of the intrahepatic bile ducts, leading to secondary biliary cirrhosis and portal hypertension. Combined liver-kidney transplantation was performed at the age of 4years, with excellent outcome. DNA analysis showed a NPHP3 (coding nephrocystin-3) homozygote mutation, confirming that this malformation complex is a ciliopathy. Conclusion: This rare association required an exceptional therapeutic approach: combined simultaneous orthotopic liver and kidney transplantation in a situs inversus recipient. The long-term follow-up was excellent with a very good evolution of the renal and hepatic grafts and normalization of growth and weight. This malformation complex has an autosomal recessive inheritance with a 25% recurrence risk in each pregnancy
