Agenesia do lobo direito hepático: um achado incomum nos exames de diagnóstico por imagem / Agenesis of the right hepatic lobe: an unusual finding in diagnostic imaging tests

ABSTRACT

Hepatic lobar agenesis is an uncommon condition observed in 1/19,000 autopsies and may be rarer in the right lobe, with about 40 cases reported in the literature. Its diagnosis is based on the non-iden-tification of the hepatic duct, the corresponding portal and hepatic veins. We describe a case of right hepatic lobe agenesis as found in abdominal imaging in a 63-year-old woman with chronic diffuse abdominal discomfort and laboratory findings of a slight elevation of liver enzymes (AU)
