Question: Ct head scan came normal overall but they said in finding: cystic changes in left frontal calvarium felt to be venous lakes? What that means, is anything else that cystic changes in the left frontal calvarium could be? It could be dangerous? Venous lakes are dangerous?
Had MrI with and without contrast of the brain and the radiologist report said normal in both. They did not mention nothing about venous lakes in the left frontal calvarium or cystic changes there.

Brief Answer:
I would believe the MRI's more precise

Detailed Answer:
Thank you for your question. You raise a point which we see all the time in the routine use of CT and MRI scans in the same patient which is when a CT scan shows something considered to be a potentially important finding but a followup MRI fails to report anything near as impressive or even fails to report anything at all.

There is a lot of artifact or image residue that occurs in a CT scanner that does not happen in an MRI due to the ability of the MRI to resolve down to much smaller structural distances and to be able to distinguish tissue types and densities compared to the rather PRIMITIVE CT. In fact, on average MRI is said to be 10x more sensitive than CT scan in detecting REAL abnormalities. Therefore, in MOST cases, if a CT scan SEES something on a brain or other organ scan that an MRI fails to see I would tend to believe the MRI scan before getting too excited about venous lakes, cystic changes, or problems in the left frontal calvarium.

It seems to me that your brain and your skull (calvarium) are just fine from the MRI read and that you shall surely live plenty long enough and be in good enough health to see many more folk trying to sell worthless swamp land in Florida to unsuspecting "dumb northerners" like me, The XXXXXXX Indians BEAT The XXXXXXX Cubs this year cuz turnaround IS fair play and THIS IS OUR year, XXXXXXX Trump get re-elected to a 2nd term of office by even LESS of a popular vote total than he did this time, and of course, the #1 reason you MUST LIVE in good health, without pathology in your brain, calvarium, or skull's because you must see MANY, MANY, MORE April 15th's so that Uncle XXXXXXX can remind you just how LOVING he is on the one hand while SPANKING you hard enough with the other to make your change and other valuables fall from your pockets and ears right into his waiting big DEEP PANTS POCKETS!

Thank you for the answer. I saw 2 neurologist, they both said my brain looks healthy and good from the MRI (with and without contrast) everything showed to be good in there. And told me that looks like a healthy brain, I do beleive MRI should be more accurate and the radiologist that made that report said that everything was normal.but the radiologist that made the CT head report said that about left frontal calvarium with some cystic changes, that feel to be venous lakes. Can they be something else? Cystic changes, does everyone has cystic in their skull? (I beleive skull in the bone/hard part of the head)
I will totally rate you and recommend you to my friends. I just need peace of mind.

Brief Answer:
Is anything 100% in this life? But this is about as close as it gets

Detailed Answer:
I've read through your clarification response and once again for all the reasons I stated above my belief (confirmed by 2 neurologists who actually SAW the pictures) is that whenever there is a CT scan and an MRI scan that say different things I always tell my patients that the MRI is the study of choice and the one we will guide therapy and intervention by...NOT the CT. The other thing is the fact that people who read CT's are sometimes not even neuroradiologists....therefore, they may overread things or think they see entities that are really not there and misinterpret artifact....I've seen that in a number of cases.

MRI's are almost always read by NEURORADIOLOGISTS who are highly trained and specialized in CT'S, MRI's and other radioimaging studies. I wouldn't even doubt if the reading neurorads doc took the CT and compared it to the MRI. Our institution does that all the time...when there is a CT and MRI the 2 are read simultaneously. Most of the time.....when it comes to contradictory's the MRI that wins out.

If the MRI doesn't show cystic changes then, the CT is either showing artifact that is being misinterpreted or the image is being OVERread by the radiologist or it's being INCORRECTLY read......putting it yet a different MRI would not likely miss something as obvious as CYSTIC changes in what is normally a very thick and bony piece of the body.....MRI would have to pick it up. Maybe the radiologist read the scan of the guy who climbed in the scanner after you???? Believe it or not....I've seen that happen as well.....

I am doing my best to give you PEACE OF MIND.....and PEACE OF CALVARIUM......please take either my son and go in PEACE to love and serve the MRI read......NOT the CT! LOL!

Once again, your fine words of feedback are greatly appreciated for these insights if they've helped you in some way. My thanks for your questions.

Hello, I am from Canada and suffer chronic pain and fibromyalgia for 25 years. I am on methadone as one treatment and it has been recently altered here. Methadose solution for pain 10mg/ml Methadone HCI 10 mg/ml. Dose, drink 1.5ml four times daily. I can not take this as I said it has been changed. Now the government has made it sugar based cherry flavored, gag reflux crap. I have tried to wean my self off but have experienced anger, smashing plates, cried out for doctor assisted suicide as the pain and withdrawal of this drug is making me crazy. I am on subcutaneous lidocaine infusions weekly, nerve blocks in neck and shoulders, cortisone injections in both hips for bursitis and nerve blocks in lower back, L4,L5. I suffer with herniated, degenerative discs, c5,c6 too. I have osteoporosis, parathesia, IBS, awaiting surgery for bladder prolapse, endometriosis which required hysterectomy and oophorectomy and numerous laporoscopies leaving me with adhesions which are a constant cause of further pain. I am a chronic pain disease sufferer and to the world I look great...haha! I initially started to write to you only for advise on taking myself off methadone but here I went on and on. The list is long and I see many doctors and pain specialists however my quality of life is nil and I am only 55 years young. I can not seem to find answers, help or hope other than being prescribed opiates, methadone which has been changed to suit the government not the patients needs and numerous medications that make me worse. I am on a roller coaster of hell and pain and now I am withdrawing off this horrible new recipe of methadone as I throw up trying to take it. Why change something that was easy to take to this horrible sugar based cherry cough medicine taste that burns to the pit of my stomach whereby I need gravol settle? I am frustrated, in pain and have talked to nurse on line tonight...she told me to go to the hospital...LOL! Right! I can not live in this doctor retired, great I have a woman who has nine kids and never can catch up or give a you know what about her patients. I give up! This is only the tip of the ice have now idea many health issues I have! I have to leave my city to go for help to Vancouver, thank God for HOPE AIR! They took me to the last appointment with my Neurosurgeon and he has ordered another MRI, will be seeing me after or before if I can not take the pain! I am a mess...What happened to good doctors??? How did we get FIBROMYALGIA??? I have a clue...DDT spraying all over the playground I grew up in...playground was a gas line and electric power field...what do you think of that? Five out of six women who played there as children were not able to conceive!!! Gee, I wonder! I am on a quest to find answers and thought perhaps I would start here...I doubt I will get an answer though...Great! Off to cyber space this goes...I am from Canada and You are in the States! Nice! I was on a Canadian all of a sudden does it go here and now I need to pay! Well, thanks for nothing....I will proceed elsewhere because I will find an answer and from you...obviously not!

Biopsy said CD 79A and Lambda were strongly positive, CD 138, Cd 3 and Kappa were focally positive in a small number of cells, CD 20 was negative. Radiation therapy scheduled for tomorrow was put off so I could get another biopsy. MRI, PET, CT scans bone marrow test show no cancer cells anywhere. The growth in my gum was painful and swollen when I got my first biopsy, but how it only looks different , is not swollen and without pain. I am taking Keppra to prevent seizures, have started prilosec 6 days ago to reduce GERD. I am a 78 year old male. I am trying to make an appointment with an endocronologist.
