1 A, Axial MRA maximum intensity projection (MIP) (TR, 34; TE, 4) shows signal intensity within the left cavernous sinus, petrosal sinus, and transverse sinus. A, Axial MRA maximum intensity projection (MIP) (TR, 34; TE, 4) shows signal intensity within the left cavernous sinus, petrosal sinus, and transverse sinus. B, Digital subtraction lateral angiogram with selective injection of left internal carotid artery. There is no evidence of venous flow, but there is some reflux into the external carotid artery. C, Conventional angiogram, late arterial phase, shows early filling of left subclavian vein (large arrow) due to ipsilateral AV fistula and retrograde flow in the left jugular vein (with the left common carotid artery superimposed) (small arrow).
