MRI of spine was suggestive of abnormal flow voids in cervico-dorsal spine (C6-D4) with intramedullary bleed (Fig.1a,b).
Figure 2: Digital subtraction angiography showing dural arteriovenous fistula (AVF) (arrow in 2a) with arterial feeder from radiculopial branches of right D6 intercostal artery Post embolization angiography showed glue cast at fistula site and no opacification of arterial feeder (arrow in 2b). Selective angiogram of feeding branch of superior mesenteric artery showing arteriovenous malformation in cecal region (arrow in 2c). Post-embolization selective angiogram shows complete obliteration of arteriovenous malformation (arrow in 2d) with patency of rest of the adjacent vessels.

Digital subtraction angiography suggested dural arteriovenous fistula with arterial feeder from radiculopial branches of left D6 intercostal artery with venous drainage into multiple perimedullary veins (Fig. 2a). AVF was done with 0.4 ml of N-butyl cyanoacrylate-lipiodol. Angiography post-embolization showed glue cast at fistula site and no opacification of arterial feeder (Fig. 2b). CT angiography of mesenteric vessels showed AVM of Iliocolic artery (Fig. 2c). Glue embolization of AVM was done under digital subtraction angiography (Fig. 2d).
