Background: cerebrovascular diseases constitute a health problem in the current world. It is outstanding the incidence of aneurysms and malformations of the anterior choroidal and posterior communicating arterial systems. Objective: to describe the anatomical norm of both systems in the adult man. Method: a descriptive study in fifty human brains obtained in the Legal Medicine Department at the Amalia Simoni University Hospital was performed. Each cerebral hemisphere was dissected with its arterial systems. Results: arteries were presented as constant vessels and they were identified fundamentally variants of origin and course, endings and forms of presentation. Conclusions: the common pattern of the anterior choroidal artery was characterized by constant origin, course with double cross with regard to the optic tract and ending like plexal artery. Variants of more significance include forms of double presentation, course below the optic tract and ending like double plexal artery.
