Pulsatile Tinnitus is a complex condition with symptoms that can range from annoying to highly disruptive.

It has various causes and can be quite difficult to diagnose both clinically and on imaging; a common radiology test ordered for its diagnosis is a CT angiogram of the head & neck.

I found this article in the EJR a while ago and it’s great; it discusses not only an optimal CT protocol for assessing this condition, but also a pictorial guide of the causes and things to check when reading these studies.

Fig. 2 Dominant sigmoid sinus and internal jugular vein A 30 year old female patient presented with right sided PT. CT A-V axial (A,C) and coronal (B, D) images demonstrate a dominant right sigmoid sinus (A, long arrow) draining into a dominant right internal jugular vein (IJV) (C, short arrow). The contralateral non-dominant left sigmoid sinus (B, long dashed arrow) and left IJV (D, short dashed arrow) are smaller in calibre.

Figure 2 from the article showing a dominant sigmoid sinus.
