      ANEURYSM OF THE ANTERIOR COMMUNICATING ARTERY ASSOCIATED WITH MULTIPLE ANATOMICAL VARIANTS OF THE CIRCLE OF WILLIS. A CASE REPORT AND LITERATURE REVIEW (ABSTRACT): The aim of this paper is to present the morphological aspects identified on head CT scans and on autopsy in an adult patient with a ruptured aneurysm located on the Anterior Communicating Artery (ACoA) and associated with an asymmetric circle of Willis (CW) due to the numerous anatomical variants of its constituting arteries. We pointed out that even though there are authors who are in favor of one or the other of the three theories regarding the mechanism of aneurysm development, i.e. the genetic predisposition, the congenital abnormalities, or the hemodynamic vascular stress, we consider that all these theories could be taken into consideration in the same patient with an intracranial aneurysm as in the case presented here we identified four different anatomical variants of the constituting arteries of the CW that were associated with a ACoA aneurysm. Our case presentation could have practical significance for anatomists from a teaching point, as well as for neurosurgeons treating a patients with a sudden subarachnoid hemorrhage as an angio - CT should be employed as early as possible to identify not only the site of a possible aneurysm, but also the possible anatomical vascular variants of CW in order to provide a better prognosis and the best chance of survival for the patient.
Key words: intracranial aneurysm, anatomical variants, circle of Willis
