“…Similar cases with multiple arteriovenous shunts close to each other that share a single drainer have been previously reported: specifically, two cases with a coexisting dural AVF and pial AVF, and two cases with a coexisting dural AVM and pial AVM. [6][7][8][9] To emphasize the presence of two arteriovenous shunts, the term "true mixed pial-dural AVM" was used in one of these cases. "Mixed pial-dural AVM" stems from the three classifications by Newton et al in 1969: "pure pial AVM" or an arteriovenous shunt with pial arterial supply only; "mixed pial-dural AVM" or an arteriovenous shunt with a pial and meningeal arterial supply; and "pure dural AVM" or an arteriovenous shunt with meningeal arterial supply only.…”

In cases of a dural arteriovenous fistula (AVF) with a pial arterial supply, postoperative hemorrhagic complications occur frequently. Six cases in which patients were diagnosed with a coexisting dural AVF and pial arteriovenous malformation (AVM) sharing a common drainer are presented. These cases were initially thought to be dural AVFs with pial arterial supplies, but careful examination of preoperative images showed that a pial AVM coexisted near the dural AVF, and that both shared a common drainer. The coexistence of a pial AVM is difficult to notice during surgery; for this reason, determining the presence of a pial AVM on preoperative imaging is essential to safely treat a dural AVF with a pial arterial supply. The details of each case, specifically, the diagnostic evidence for this condition (coexisting dural AVF and pial AVM sharing a common drainer), as well as imaging findings that should be noted, are presented.
