In this study thirty pampas fox brains (Pseudalopex gymnocercus) were used, injected with red stained latex. The objectives were to systematize and describe the distribution and the vascularization territory of the caudal cerebral artery. This artery was originated from the caudal branch of the internal carotid artery, and through its course, the main axis emitted the rostral tectal artery, branches to the piriform lobe and caudal choroidal branch as collateral branches, and continuing, from where it emits the caudal medial hemispheric branches, as the caudal inter-hemispheric artery. The vascular territory of the caudal cerebral artery of the pampas fox was formed by the adjacent areas of this vessel route over the ventrolateral surface of the cerebral peduncle, caudal third of the piriform lobe, rostral colliculus, the rostral part of the caudal colliculus, the pineal body, the medular stria, the habenula, the dorsal surface of the thalamus, the medial and lateral geniculate bodies, the hippocampus, the parahippocampal gyrus, the choroid plexus of the third and lateral ventricles, the splenium of corpus callosum, the caudal third of the medial surface of the cerebral hemisphere and the limiting edge of the convex face of the cerebral hemisphere within its caudal pole.
