DSA showed a large feeding vessel on the left at the T6 level; this was supplied by a single "hole fistula" extending through the left T3/4 foramen and was accompanied by a venous "side" aneurysm [Figure 2]. Endovascularly, the fistula and venous aneurysm were closed with two coils and a small amount of embolic agent - precipitative hydrophobic injectable liquid-25 [Figure 2].
