As noted in several other pulsatile tinnitus pages here, the relationship between venous hypertension, PT, and venous sinus stenosis continues to be defined. Some believe venous stenosis to be the long-sought cause of IH, others feel that high CSF pressure … Continue reading
Here is a more nuanced case of venous pulsatile tinnitus. Venous sinus stenosis is perhaps the most under-recognized cause of pulsatile tinnitus today. See Venous Sinus Stenosis page and Cases 1 and 2 of venous sinus stenosis and stenting for … Continue reading
The most under-recognized cause of pulsatile tinnitus is venous sinus stenosis. It is a common and usually asymptomatic / incidental finding. However, that is not always the case. Some patients develop pulse-synchronous tinnitus due to turbulent flow across the area … Continue reading
Venous sinus stenosis is the most under-recognized cause of pulsatile tinnitus. Venous sinus stenosis, particularly of the sigmoid sinus, is common and, in vast majority of cases, asymptomatic. Which is why it is usually overlooked on imaging studies. Many patients … Continue reading

Venous pulsatile tinnitus is one of the most common causes of this under-recognized disorder. The hallmark of venous tinnitus is the ability of patient to suppress the sound by ipsilateral jugular compression, which reduces flow in the entire ipsilateral transverse/sigmoid/jugular … Continue reading
A well-known association between pulsatile tinnitus and intracranial hypertension is now established. Most patients with significant IH have at least sigmoid sinus stenosis. The chicken/egg question of what begets what remains unsolved. Does high CSF pressure collapse the sinus? Or … Continue reading
Introduction to Cerebral Angiography and Its Role in Modern Diagnostic Imaging Unlike most parts of this website, this page is primarily intended neither for the patient, nor for an angiographic trainee / practitioner. Its target is a medical professional, … Continue reading
Brain Dural Arteriovenous Fistula (BDAVF) This page is intended as a source of information and education for patients suspected of or having been diagnosed with a brain dural fistula. Please remember the “Disclaimer” — none of this information may be used … Continue reading
Superficial Cortical Venous Network An extensive network of interconnected veins running within the sulci, highly variable in size, route, and drainage pathway subserve venous egress of the cerebral convexity. These veins typically drain the cortex, u-fibers, and some underlying deep white … Continue reading
