The cerebral arterial circle plays a crucial role in the blood circulation within the cortical area. Its’ morphological variability and potential for the formation of aneurysms are well documented and constitute significant mortality risks. Within the Forensic Medicine Department, several anomalies within the area were identified during the autopsy of a 29 year old male. The observations included anomalous origins of the arteries constituting the cerebral circle (anterior and posterior parts), left/right vascular asymmetry and the presence of an aneurysm which had ruptured spontaneously and was identified as the cause of death. On the anterior part of the circle, both cerebral arteries originate from the left internal carotid artery, through a 2cm common trunk. The 0.3‐0.4cm saccular aneurysm was located at the bifurcation of this trunk. The right anterior cerebral artery anastomosed with the the middle homolateral cerebral artery through a 4.5cm long and 0.2cm in diameter branch. On the posterior part of the circle, agenesis of the right posterior communicating artery was highlighted. Through their effect on hemodynamics, morphological anomalies in vessels such as those identified in this case may constitute causal factors in the development of aneurysms.
