Riedel's lobe, a false impression of hepatomegaly

Hepatomegaly is a relatively frequent clinical sign in the examination of the pediatric patient. This may be due to a hepatic disease or a generalized disease with hepatic involvement. A variant of the normal right hepatic lobe is the called Riedel´s lobe, which can sometimes be interpreted as hepatomegaly. These patients are asymptomatic and have no clinical or laboratory signs of the liver disease. We present the case of a 4-year-old boy in whom a radiological hepatomegaly was found by chance.
