Atypical polysplenia only with absence of the hepatic segment of inferior vena cava in a middle-aged.
An autopsy case of polysplenia with absence of the hepatic segment of the inferior vena cava in a 53-year-old female is reported. The venous blood from the lower parts of the body was drained through the azygos vein and the superior vena cava into the right atrium. Other than acquired pathological change, the heart was found to be normal. Except for the partial absence of the inferior vena cava, isomerism of asymmetric organs, and heterotaxia of abdominal organs, characteristic of typical polysplenia, were not present. This case of atypical polysplenia suggests the presence of a transitional form in the complex.
