This study intends to describe an anatomical variation found in a routine dissection of a male cadaver. The main renal artery had originated in the abdominal part of the aorta artery and followed his course until its entrance on the renal hilum; however instead of a rectilinear trajectory from the aorta it had a descending and quite angular trajectory. From the main renal artery arises an anomalous polar artery that enters in the inferior polo of the right kidney. This anomalous artery starts 51,88 mm after the origin of the main renal artery. On a lower level, at the same height as the aorta bifurcation arise another anomalous polar artery that enters in the renal hilum following a rectilinear trajectory until the inferior polo of the right kidney. There is a vast range of branches that supply the superior and inferior polo of the kidneys originating directly from the aorta or from the main renal artery and that is widely described in literature, however there is no general agreement between the different authors about the nomenclature used in the description of each case.
