[Congenital hepatic fibrosis associated with choledochal cyst]
Insights
This case report details a rare pediatric liver mass associated with renal cysts and congenital hepatic fibrosis. The findings suggest a potential incidental association between choledochal cysts and hepatorenal fibropolycystic disease.
Area of Science:
- Pediatric Gastroenterology
- Hepatology
- Medical Genetics
Background:
- Congenital hepatic fibrosis (CHF) is a rare autosomal recessive disorder characterized by fibrosis of the liver and bile duct abnormalities.
- Choledochal cysts are congenital dilations of the bile ducts, often presenting in childhood with abdominal pain, jaundice, or a palpable mass.
- The co-occurrence of CHF and choledochal cysts is exceptionally rare, with limited documented cases.
Observation:
- A one-year and eleven-month-old female presented with an asymptomatic hepatic mass.
- Radiological examination revealed a well-defined hepatic tumor and renal cysts.
- Laparotomy identified a choledochal cyst, and liver biopsy confirmed congenital hepatic fibrosis.
Findings:
- This case presents a unique combination of congenital hepatic fibrosis, choledochal cyst, and renal cysts in a pediatric patient.
- Pathogenic mechanisms of both CHF and choledochal cysts were analyzed.
- The study suggests that the choledochal cyst may be incidentally associated with the hepatorenal fibropolycystic disease in this patient.
Implications:
- This case highlights the importance of considering rare congenital anomalies in pediatric patients with liver masses.
- Further research is needed to elucidate the potential relationship, if any, between choledochal cysts and hepatorenal fibropolycystic disease.
- Accurate diagnosis and understanding of these associations are crucial for appropriate patient management and genetic counseling.
Abstract:
The purpose of this work is to report the case of a one-year and eleven-month-old female child who presented with an asymptomatic hepatic mass; on x-ray examination a well limited round tumor was seen as well as renal cysts. A choledochal cyst was found upon laparotomy; the liver biopsy exhibited congenital hepatic fibrosis. This association is not clearly defined in the literature review made, making this perhaps the first well-documented case with this combination. We analyze the pathogenic mechanisms of both disorders and conclude that choledochal cyst is probably not related to hepatorenal fibropolycystic disease; this could be a casual association in our patient.
