What does a high riding jugular bulb mean?

High riding jugular bulb is defined as an extension of the most cephalad portion of the Jugular bulb superior to the floor of the internal auditory canal or it can projects above the basal turn of the cochlea [2].

How do you treat a high riding jugular bulb?

Disabling vertigo induced by jugular bulb abnormalities can be effectively treated by an endovascular technique. This technique is minimally invasive with a probable greater benefit/risk ratio compare with surgery.

Can high riding jugular bulb cause pulsatile tinnitus?

It is believed that venous sinus stenosis and a high-riding jugular bulb with diverticulum are associated with turbulent blood flow near the middle ear, and therefore are responsible for objective pulsatile tinnitus.

Is a jugular bulb normal?

Asymmetrically large jugular bulbs are entirely normal and asymptomatic; its only significance is to distinguish it from pathology. The size of the jugular bulbs is variable, with the right side being significantly larger than the left in two-thirds of people.

What does the jugular bulb do?

The jugular bulb (JB) is the confluence of the lateral venous sinuses situated in the jugular fossa. It drains extracranially to the internal jugular vein as it passes through the jugular foramen of the posterior cranial fossa.

Can neck problems cause pulsatile tinnitus?

Pulsatile tinnitus can be caused by problems in the arteries or veins of the head, neck, or both.

Can the jugular vein be removed?

Internal Jugular Vein: The internal jugular veins are large veins on either side of the neck that help to drain blood from the brain and head back to the heart. One jugular vein can be removed without causing any symptoms.

What are the symptoms of high riding jugular bulb?

Jugular bulb anomalies such as high-riding jugular bulb (HRJB), dehiscence of the jugular bulb, and jugular diverticulum are often encountered in clinical practice, and in most patients, they are asymptomatic. However, in rare cases, patients may present with symptoms such as tinnitus and more rarely, conductive hearing loss (CHL). [1–4]

What are the symptoms of a jugular bulb diverticulum?

High-resolution CT-angiography is the method of choice, but because it is associated with some radiation, it is generally not the best choice as a screening procedure. On CT, a jugular bulb diverticulum is characterized by continuity with the jugular bulb, smooth edges, and absence of bony destruction.

What is high riding jugular bulb with dehiscent sigmoid plate?

Clinical perspective: High riding jugular bulb with dehiscent sigmoid plate is an anatomic variant that may be associated with tinnitus. The differential diagnosis of tinnitus encompasses a variety of aetiologies, however, pulsatile tinnitus points to an underlying vascular aetiology.

Can a high jugular bulb cause hearing loss?

When present, the high jugular bulb can be associated with bleeding during surgery. When it comes into contact with inner ear structures, it can cause tinnitus, hearing loss, a conductive hyperacusis, and Meniere’s diseasetype symptoms. Tinnitus is attributed to a direct pressure wave from the Jugular.
