Summary
A new case of an unusual anomalous anastomotic vessel between the carotid syphon and the pericallosal artery is reported. The description of their most characteristic angiographic and anatomical features is completed with a survey of analogous anomalies found in the literature. The incidence of associated other congenital vascular anomalies and berry aneurysms is high. An explanation of the embryonic development of this vessel is hypothetical. Its angiographic recognition may be useful.
