Question 1

need advice on 5mm prominent structure on mri. possible jugular bulb. all prior mris have been ok.  symptoms, facial differences and unsteady gait.

Accepted Answer

Neuroradiologist: Make sure the study was read by a neuroradiologist. If the radiologist who read it has group associates with neuroradiology training they will usually be happy to provide a second look at your study without cost.

Question 2

what does this mean? asymmetrically diminutive left transverse sinus, likely congenital, as evidenced by an asymmetrically diminutive left jugular bulb and jugular vein?

Accepted Answer

: If this is the sole remarkable finding, the report indicates the presence of a congenital variation of no pathological consequence.

Question 3

dominant l jugular bulb is seen with tiny infundibulum. there is varient venous anatomy at the l base of skull with a prominent venous/vascular structures/sinus and anastomosing with the jugular bulb and extending extracrainially. means?cause pt?bad?

Accepted Answer

Radiologist report: Ought to be discussed with the ordering physician, can't comment on the findings, have to be clinically correlated, best wishes

Question 4

mri due to migraines. mri report said,  high riding left jugular bulb and cerebellum tonsils low lying but no chiari. what symptoms would i experience with each of these?

Accepted Answer

None: Those are “normal” anatomical variants and have nothing whatever to do with migraines. The physician who ordered the MRI has the ethical obligation to review the report with you and interpret it in terms you can understand, or, if they can’t, to find someone who can. You have a right to expect that. Remember that for the future.

Question 5

migraine history mra/mri results: right a1 anterior cerebral artery is hypoplastic. right p1 posterior cerebral artery is markedly hypoplastic. low lying cerebellar tonsils, no chiari. borderline high riding left jugular bulb.what's the significance?

Accepted Answer

How it is: The description you provided describes the anatomy seen on the MRA/MRI
The significance needs to be correlated with your clinical exam and findings.
Without more information difficult to say much more. Consult your ordering physician for complete diagnosis.

Question 6

explain my anomaly: sup. sag. sinus extending into posterior fossa in the midline w/bifurcation into two veins draining into jugular bulbs?

Accepted Answer

Not an issue: You just possess a variation of some of the venous drainage in the brain, and has no pathological significance.  Has nothing to do with your headaches or dizziness.  Ask you doctor why you possess these issues, and what treatment might help.  Maybe see a neurologist.

Question 7

what will happen if your jugular is cut?

Accepted Answer

It could lead to: death.

Question 8

what can jugular pulses indicate?

Accepted Answer

Venous Pulse: The jugular venous pulse can be helpful in differentiating some types of cardiac vs pulmonary conditions.

Question 9

what causes jugular venous reflux?

Accepted Answer

Physiology: The jugular vein connects directly to the superior vena cava and then to the right atrium of the heart. When the heart is overfilled, the jugular vein becomes distended. If you press on the liver, you  can accentuate this ("hepato-jugular reflux") and that observation is used to increase the sensitivity of the physical exam for early signs of heart failure.

Question 10

how is vein ( jugular ) examined ?

Accepted Answer

Several ways: On physical exam the examiner can observe the pulsations in the neck. This requires some skill and not all physicians are experienced in this. A Doppler test can evaluate the flow in the internal jugular veins. Computed tomography can also evaluate the venous flow when contrast is injected. Thanks for trusting HealthTap!
