Anomalous Origin of the Artery of Davidoff and Schechter Confirmed in a Case of Dural Arteriovenous Fistula of the Superior Sagittal Sinus

Angiography revealed feeders from an exceedingly rare variant of ADS branching from the P4 of the PCA.

Typically, the ADS supplies only the dura mater; however, it can also have branches that extend to the brain parenchyma. Thus, thorough angiographic evaluation is essential when addressing conditions in falcotentorial regions that involve ADS.
