ABSTRACT: Introduction: In the embryonic period, several developmental anomalies of the cerebral arteries occur. The knowledge of these anatomic variations is important to avoid unnecessary surgery and to undergo surgery or interventional radiology with safety. Objective: In this report, we discuss the hypothesis of the presence of azygos anterior cerebral artery as a possible cause of anisocoric pupil found in a patient with 35 years old. To our knowledge, this variation has not been previously reported. Results: In this study we reported a case of this artery emphasizing some morphological, functional and clinical data about this rare vascular abnormality. Conclusion: The results could be important to offer useful information to anatomists, radiologists, ophthalmologists, neurologists and head and neck surgeons.
