Doctor insights on: Periventricular gliosis
Had MRI of brain due to persistent headaches caused by head trauma. Impression mentioned mild periventricular gliosis. What does it mean?
Brain cell injury:
It means you may need more tests
'gliosis: a process leading to scars in the central nervous system that involves the production of a dense fibrous network of neuroglia (supporting cells) in areas of damage. Gliosis is a prominent feature of many diseases of the central nervous system, including multiple sclerosis and stroke. After a stroke, neurons die and disappear with replacement gliosis.'. ...Read more
If I have Right periventricular white matter likely Gliosis can I have symptoms of hand weakness and foot on the same side if it's MS?
No: Doesn't matter whether it's MS or anything else: stroke, tumor, anything: ANY lesion in the right hemisphere causes signs & symptoms on the left. Exceptions are a few left-handers & a VERY tiny proportion of right-handers. Southpaws have either left hemisphere dominance just like righties, or they have so-called mixed dominance. True right hemisphere dominance is exceedingly rare. ...Read more
MRI scan shows two small focal flair hot spots in either frontal lobes subcortically and Mild peri ventricular gliosis. What does it mean.
MRI scan shows two small focal flair hot spots in either frontal lobes subcortically. Mild peri ventricular gliosis. Age related mild diffuse atrophy.
Probably not...: ...significant. A few small lesions can be seen in many patients without an underlying problem. If there is any concern, then a repeat MR in 4-6 months can be performed. Without any interval change, then you should not worry. However, atrophy at your age is more worrisome and not common, and your Doctor should examine you closely for any underlying cause. ...Read moreSee 1 more doctor answer
Ventricular irritab: Assuming you are referring to pvc's or premature ventricular contractions - besides myocardial ischemia the most common cause I see is caffeine ingestion - followed by stimulant ingestion ie pseudofed. Cocaine and other illicit drugs as well as add drugs can cause irritability as well. Elimination of these will generally solve the problem if not its time to see a cardiologist. ...Read moreSee 1 more doctor answer
Cellular level: Irritability refers to enhanced ability of the heart cells to generate an electrical impulse (known as action potential). This happens when a substance referred to as cyclic amp increases in the heart cell causing increased entry of calcium into the cell. With increased calcium, the heart cell both fire impulses rapidly as well as contract vigorously. I will go over some of the causes next. ...Read moreSee 1 more doctor answer
Echocardiogram: This is most commonly done with an echocardiogram, an ultrasound of the heart. It is also assessed when dye is injected into the heart at the time of a cardiac catheterization or by the injection of radioactive substances into the heart, which is commonly done as part of a stress test. ...Read moreSee 1 more doctor answer
A foramen ovale (pfo) is a small hole between the two upper chambers of the heart. It exists as part of the "fetal circulation, " when babies are inside, lungs are full of amniotic fluid. The pfo allows oxygenated blood returning from the placenta to cross into the left atrium.
Pfos usually close, however if they do not there is a very small risk for a stroke or tia.
Most people have no symptoms. ...Read more
Abnormal heart rhyth: It means that the heart is not beating in sinus rhythm. The normal conduction is not present. The person is likely being seen by a cardiologist who will decide how best to treat. ...Read more
Ejection fraction: The left ventricle exists to pump blood throughout the body. During each heartbeat, the ventricle pumps a certain fraction of the blood it receives. A well preserved function means that the ventricle is maintaining its ability to pump blood efficiently throughout the cardiovascular system. During heart failure, the ventricle typically loses this ability. ...Read more
No where: Lv failure (i assume you mean reduced pumping power) does not result in any specific ECG findings. In fact, the ECG can look completely normal! On the other hand, in many patients, a whole range of abnormalities can be seen, including evidence of prior heart attacks (myocardial infarctions), conduction system disease, thickening of the heart muscle (hypertrophy), etc. See your doctor. ...Read more
I was told by a nurse that my test results showed I have ventricular tacicardyah, how worried should I be?
Get the facts: All fair-minded people respect nurses, and in fact they do much more than we doctors do to keep sick people alive and comfortable day-to-day. If you have real ventricular tachycardia, it'll take your breath away at best, and your physician (not the nurse) will have told you about it already and initiated appropriate treatment. Any doubts, get a second physician's opinion. ...Read more
What is the normal size of the rv in a adult? Right ventricular its 2.7 to what? And at how big is it dangerous?
Depends: It depends on where you are measuring the RV from. As based on the low normal your report, this is likely a mid RV diameter measure. At this point in the heart, normal is from 2.7- 3.3cm. In regards to dangerousness, this is a complicated answer. It depends on why it's enlarged but also how the function (pumping ability) is too. ...Read moreSee 1 more doctor answer
What is the difference between right ventricular mild enlargement and cardiomyopathy? Or is it basically the same, thing?
Can you tell me how is the magnitude of the isovolumetric relaxation altered by the increase of the ventricular lusitropy?
Increased: Isovolumetric relaxation is one of the most miraculous properties of the heart that needs to "actively relax" by untwisting in order to accommodate incoming blood in diastole, the relaxation phase of the cardiac cycle that produces the lower blood pressure number. Lusitropy is a term describing capacity for diastolic relaxation and isovolumetric relaxation increases with increases in lusitropy. ...Read more
