Quantitative and morphological analyses of different types of human liver

ABSTRACT

Morphological variations in the human liver have been classified as congenital or acquired, although some mayresult from pseudo-injuries incurred during medical investigation. The present study comprises a systematicanalysis of the anatomical variations exhibited by 61 formalinised and glycerinated adult human livers derived from a collection maintained at the Institute of Anatomy, Universidade Severino Sombra, Vassouras, RJ, Brazil. The vast majority of the organs analysed could be classified according to the seven morphologicalliver types previously established, although two additional liver types were identified and described. Detailedknowledge of anatomical variations in the human liver could be valuable in improving diagnostic proceduresand in attaining a better understanding of pathological conditions associated with some liver diseases.
