Abstract

Introduction. The fetal variant of the cerebral posterior artery is a Willis' circle variant in form characterized by its origin from internal carotid artery instead of basilar artery, associated with hypoplasia of its PI segment. This functional bifurcation is present in 10-15 % of population, and it has been always considered as phistological and with no significative effects on cerebral blood flow. In scientific literature an association with epileptic sindrome does not exist . Case report.. Here it is described a report of a patient, with no familiar epileptic hystory , suffering since five years of partial versive epileptic seizures with secondary generalization, which did not stop with pharmacological therapy.Various neuroradiological and neurosonological texts ( Transcranial doppler sonography , Transcranial Power Doppler Imaging , CT, NMR, Angio-NMR), showed absence of cerebral parenchymal lesions and presence of the fetal variant in form of posterior cerebral artery. Discussion. The type of epileptic seizures ( versive and so of frontal lobe origin, supplied by anterior and middle cerebral arteries), their start (during physical excercise and during menstrual period), may suggest a possible altered blood supply of some cerebral territories supported from this vessel in particular conditions.
