The paper covers the structure of the arteries of the encephalon base in roe deer and a range of vascular variation in the area. The final shape of the vascular tree is affected by many factors classified as intracorporal and extracorporal. Variation in the region of arteries of the encephalon base could be presented by considering variation in intervascular connections, variation in the descent of respective vessels and the asymmetry of the same arteries. In all animals examined, the greatest range of variation was observed in the pattern of anastomosis of rostral cerebral arteries and in the descent of rostral cerebellar arteries.
