Bilateral High-Riding Jugular Bulb and Jugular Diverticulum Dehiscents into the Mastoid cells and Trautmann’s Triangle

High-riding jugular bulb is a common abnormality that involves the jugular bulb. It corresponds to a jugular bulb higher than a specific anatomical landmark, which is still controversial. A diverticulum may grow up from the jugular bulb dome in different directions. The jugular bulb may be well-corticated or, on the contrary, dehiscent when the bony cover is deficient. All these anatomical conditions may still be asymptomatic or provoke debilitating symptoms or surgical complications. In this case report, we present a 30-year-old man who suffered from debilitating vertigo and pulsatile tinnitus that hindered his quality of life. Temporal bone high-resolution computed tomography revealed bilateral high-riding jugular bulb, right jugular diverticulum, and right-side dehiscence into the mastoid cells and Trautmann’s triangle. The patient was managed conservatively but without significant symptom relief. This case report highlights an uncommon presentation of dehiscent high-riding jugular bulb and jugular diverticulum that, to the best of our knowledge, has not been reported before.
