Type C, A 43-year-old woman with a right direct carotid cavernous fistula.

A, Frontal view of a right carotid arteriogram demonstrates a right carotid cavernous fistula. Retrograde opacification of the SMCV is not shown.

B, On the contrast-enhanced gradient-echo MR image, 2 SMCVs are conjoined beside the cavernous sinus and flow through the middle carnial fossa (arrows). This patient was treated by transarterial and transvenous coil-packing of the right cavernous sinus.

C, The carotid angiogram immediately after embolization demonstrates no visualization of the shunt. Note the right SMCV flowing beside the coil mass (arrows).
