Progressive tubulointerstitial nephropathy with hepatic involvement in an infant

We describe an infant with renal and liver disease who died at the age of 10 months from chronic renal failure. Hepatosplenomegaly was present along with biochemical findings of cholestasis and cytolysis. The diagnosis of tubulointerstitial nephropathy with cortical microcysts associated with hepatic fibrosis was based upon laboratory, radiological, and histological data. This rarely described disorder is characterized by an early clinical onset and unfavourable progression to end-stage renal failure before the age of 2.
