TABLE 1:

Summary of Case Series of Patients With Colocalized High Signal Intensity on Both Arterial Spin Labeling and Time-of-Flight MRA in Left Jugular Foramen Without Dural Arteriovenous Fistulas

Case	Indication for Initial Imaging Study	Side	Diagnostic Confirmation
1	Workup of new seizures	Left (nondominant)	MRA (TRICKS), DSA
2	Workup of acute stroke	Left (nondominant)	CTA, DSA
3	Incidental finding	Left (nondominant)	Resolution on follow-up MRI-MRA
4	Pulsatile tinnitus	Left (nondominant)	DSA
5	Pulsatile tinnitus	Left (nondominant)	DSA
6	Workup of acute stroke	Left (nondominant)	DSA
7	Nonpulsatile tinnitus	Left (nondominant)	Stable on follow-up MRI-MRA; resolution of symptoms

Note—TRICKS = time-resolved imaging of contrast kinetics, DSA = digital subtraction angiography.
