One of the question therefore is will a regular MRI or CT scan with/without contrasting dye show CVT? I'm not sure, because if it does, then why does a venogram even exist?

Also, if there is blood clotting, which would explain my symptoms: right nasal sinus congestion, right temporal lobe ache, lower right occipital pain + slight edema, and the recurring tenderness along sagittal sinus. I think this probably qualifies for intracranial pressure, wouldn't a physician want to see a venogram? How many other people in our society are carrying blood clots that will potentially cause strokes that couldn't otherwise be detected by a 2 min scan?
And shouldn't the back pressure be measured anyhow? The studies I've seen discuss the flow of blood into the aneurysm, but I haven't seen anything discuss venous blood (sinus) thrombosis (CVT, CVST) except that leads to sub arachnoid hemorrhage (SAH), which is deadly. The medical professionals will check your blood pressure, but if the pressure is different in your head, then what good will systolic/diastolic monitoring be? Unless of course, if its too late, maybe. idk.

More questions. More studies.

trojanbrain, welcome!

I can't answer your specific questions but there is this about the causes of brain aneurysms:

Brain aneurysm - Causes
- NHS

My daughter had a (ruptured) brain aneurysm, and at the time I was told that anything that raises blood pressure could cause an aneurysm to rupture.

I'm very sorry guys but I think you misunderstood my posts. I wasn't here seeking support, but trying to help others. I was breaking up my posts because they would drag on too long**

I can add some information for others.

Please use Google Scholar to look up the recent studies relating to cerebral aneurysms.

Consider using glycine as a supplement. This has been found to prevent damage if rupture/stroke occurs and may even mitigate aneurysms themselves. Also include ice packs to the head as this causes hypothermia neuroprotection. These are items you should have around the house in case of emergency if a stroke happens.

Also look up the recent research on CoQ12 (ubiquinone) and metformin as these compounds appear to attenuate (stop) aneurysm progression.

There are some rare cases in which aneurysms spontaneously disappear (!)

Small saccular aneurysms are generally safe unless they are irregular in shape, in which case, they may rupture anytime.

I also advise people here to review how to reverse plaque/arteriosclerosis formation, which is possible. This is partially related.

Hemodynamic blood flow is familial because the way your arteries are shaped during development (as determined by genetics), which influence the development of aneurysms. If someone in your immediate family has been diagnosed with an aneurysm, I strongly recommend your family members and you undergo screening.

God bless you all.
