Diagnosis of Congenital Hepatic Fibrosis in Adulthood.

OBJECTIVES: We studied clinicopathologic features of congenital hepatic fibrosis (CHF) that could aid the diagnosis of this relatively rare condition during adulthood.
METHODS: Five consecutive adult CHF cases were identified in a single institution.
RESULTS: Clinical manifestations of CHF varied from asymptomatic to requiring liver transplantation. Three of five cases had other disease associations, including Joubert syndrome, Caroli disease, polycystic kidney disease, and congenital anomaly of hepatic vasculature. No unique common radiologic findings were found. Histologically, all cases showed characteristic abnormal interlobular bile ducts embedded in fibrotic portal stroma, with varying degrees of liver fibrosis.
CONCLUSIONS: While other disease associations and characteristic liver histomorphology are helpful clues to suspect the diagnosis of CHF in adult patients, other differential diagnoses should be excluded clinically and radiologically. This study highlights the importance of a multidisciplinary diagnostic approach by pathologists, radiologists, and hepatologists for the accurate diagnosis of CHF during adulthood. © American Society for Clinical Pathology, 2019.
