Evaluation of long-term results of Caroli's disease: 21 years' observation of a family with autosomal "dominant" inheritance, and review of the literature.
A 5-year-old girl underwent laparotomy in 1972 because of hepatomegaly and mottled radiopacities shown by cholangiography. Polycystic segmental dilatation of the intrahepatic bile ducts, typical of Caroli's disease, was found. Thereafter she remained in good health for over 21 years with careful medical management. In 1972 mottled radiopacities of the hepatic parenchyma were also demonstrated by cholangiography in her 9-year-old brother, who, however, remained asymptomatic until hematemesis due to esophageal varices suddenly occurred in 1993. At the time of the pre-operative evaluation for esophageal transection, his condition was definitively diagnosed as Caroli's disease. Their father was in good health, but in 1993 was shown by CT to have the same disease. The mode of inheritance is likely to be autosomal dominant, although Caroli's disease or congenital hepatic fibrosis is generally considered autosomal recessive (McKusick number 263200) (1). If we had not examined the father, this particular family would have been accepted as an example of autosomal recessive inheritance. We suggest that further family studies are needed to exclude the autosomal dominant mode of inheritance, and that at least some of the recessive cases in the literature are, in fact, autosomal dominant. Well-documented cases of "classical" Caroli's disease in the literature were reviewed with special reference to the long-term results. In addition, an international questionnaire aimed at establishing the further clinical course of the patient was sent to authors who reported cases after 1968.(ABSTRACT TRUNCATED AT 250 WORDS)
