Tentorial dural arteriovenous fistulas (TDAVF) are an uncommon subgroup of dural arteriovenous fistulas (dAVF). The clinical course
of TDAVFs is more aggressive compared to other types of dAVFs. Most cases present after a hemorrhagic stroke. Only a limited
number of cases are diagnosed prior to hemorrhage; therefore these cases are referred to early treatment due to the aggressive
behaviour of these pathologies. Treatment has classically been based on microsurgery but the treatment modality has shifted
to endovascular methods in the last two decades. This paradigm shift is mainly due to the widespread use of Onyx, a liquidbased
non-adhesive endovascular material. This article describes the diagnosis, clinical course, several classification systems, and
endovascular treatment methods of TDAVFs.
