<jats:p>Tentorial dural arteriovenous fistulae (TDAVFs) are complex lesions with the arteriovenous fistula located between the leaves of the tentorium cerebelli. While a large portion of dural arteriovenous fistulae are treated endovascularly, TDAVF may require additional microsurgical treatment given their high risk of hemorrhage and multitude of feeders. We describe the case of a 65-year-old male who presented with hemorrhage from a straight sinus and galenic TDAVF. The straight sinus portion of the fistula was obliterated by 3 endovascular treatments and 1 microsurgical treatment. The galenic component of the TDAVF persisted and was approached via a posterior interhemispheric approach in a lateral position. This video demonstrates surgical technique and anatomy associated with this rarely seen dural arteriovenous fistula.</jats:p><jats:p>The video can be found here: <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="https://youtu.be/iOLzWOabLZ0" ext-link-type="uri" xlink:type="simple">https://youtu.be/iOLzWOabLZ0</jats:ext-link>.</jats:p>
