Neurofibromatosis and Caroli's disease: an extremely rare association.

Neurofibromatosis type-1 (NF-1) is a rare genetic disorder with an extremely variable phenotype. A broad spectrum of associations have also been reported with it. We present a florid case of NF, presenting with unusual symptoms, which was found to have an associated Caroli's disease, a rare congenital disorder of the intrahepatic bile ducts. The case is reported along with a brief review of both the disorders.
