Persistent basilar/middle meningeal artery anastomosis.
Three cases of a basilar/middle meningeal artery anastomosis are demonstrated angiographically. No reference to previous angiographic demonstration of this vascular anomaly has been found in the literature, and only one similar case with an anatomical description has been located. An embryological explanation of this rare anastomosis is presented.
