User :   Hello, I just recieved an mri, but my doctor is out for the day. I'll still go to him, but I am curious about some of the things in my report. My mother has an avm so I most concerned about that. I have headaches and vertigo.
The report says "nonspecific, increased, bright signal about the lateral ventricals. Differential diagnosis includes remote, congenial insult, small vessel disease, and chronic ischemia." What does this all add up to? Could it be an avm? AVM is not mentioned in the report. The report also says "no mass."
Doctor :   hi
Doctor :   Dr
User :   hello
Doctor :   let me read ur query
User :   okay
Doctor :   no this is not an avm
User :   okay, would it say "avm" in the report?
Doctor :   AVM can be diagnosed by a MRI angiography
User :   alright, but would any of the things listed here in my mri report suggest an avm?
Doctor :   no
Doctor :   not at all
Doctor :   may i know your age ?
User :   okay, what is a congenital insult? Just an injury before birth? 33.
Doctor :   yes, injury during birth
Doctor :   like reduced blood supply during birth can cause brain damage
User :   Okay, so does this mean one-time injury? Like non progressive?
Doctor :   yes
Doctor :   low blood supply induced damage can present in this way
Doctor :   including atherosclerosis
User :   Okay, and chronic ischemia. I know that means chronic loss of oxygen. So, this can't be from an avm? What will it do to me, if anything, in my lifetime?
Doctor :   no it cannot be due to an AVM
Doctor :   NOTHING much damage can result out of it
User :   Okay, last thing, the bright spots, these are what? areas damaged by the low oxygen?
Doctor :   they are due to presence of fluid in the third ventricle , and that is normal
User :   everybody has them, or its just common?
Doctor :   every body has the hyper intensity due to the third ventricle
User :   okay, so none of this can be an avm at all? The avm would look like something else?
Doctor :   yes this is not an AVM
Doctor :   a AVM can be diagnosed by a MRI angiography as a abnormality in the vasculature
Doctor :   the MRI can detect any bleeding due to a ruptured AVM , which is not the case with u
User :   okay, so does this report hold anything bad? The chronic ischemia, can that increase a stroke or anything?
Doctor :   no
Doctor :   its not a stroke
User :   okay, thanks. Just curious, you are an MD? speciality?
Doctor :   I am a Internist , MD
User :   where in the world are you practicing?
Doctor :   INDIA
User :   alright
User :   well, thanks
User :   I think that clears up everything
Doctor :   You are welcome
