suspected mesial temporal ganglioglioma

Posted by

hello everybody,
im new to the group and english is not my first language, so sorry for the mistakes.
i've been diagnosed of a ganglioglioma (low grade glioma) in my right mesial temporal lobe.
it was discovered by errors, because i bugged my doctor for a rmi.
i had a really strange flu, tinnitus and a kind og ghost image problem in my right eye.
so i had the scan february and then one with contrast liquid in march.
I went to the hospital of my town where neurology is a must and they told me take it easy is a loww grade tumor, see you in six month
so i went in another town to a super brain surgeon , and he told me is 99% a ganglioglioma or dnet.
so wait 6/8 months and repeat the mri with contrast and enjoy the summer.
last month i went to milan , at neurological hospital, that is a real super place for all this.
i takled with a neurooncologist, neuroradiologist and radiotherapyst.
he confirmed me the same thing and asked me if i wanted to be followed by thei team of specialists.
i said yea.
they called me after a month yesterday.
they discussed my case and they wnat me to spend some day by the center to check some tests, because i should have symptoms(seizures) that i really don't have.
repeat the mri and decide what is going to happen. if i have to take surgery or other therapy.
they told me nothing is changed from the last month. but the place where i have this lgg is really serious.
im totally scared.
im really scared.

Hello Isaw,

Sorry your post hasn't had a reply yet. How are you feeling now? Have you had any more results back?

Hopefully this will bump your post up and someone with more knowledge will be able to help you.

Take care,

Hi there

i face pretty much the exact same situation: suspected right temporomesial lobe ganglioglioma or DNET (head of hippocampus, amygdala, some parts of uncus). 

it was found by accident roughly 1 year ago. i also have no symptoms (no seizures etc). I am 50 years old. 

after having seen multiple experts (neurosurgeons, neurologists, epileptologists) I have decided to NOT have surgery. As i have no symptoms i also have no other therapy but rather live my normal life as before this was found (except yearly MRIs to check up).  

Gangliogliomas and esp. DNETs are benign. Prognosis is excellent. Being a trained neuropsychologist myself, I have read most available research papers on these tumors. I feel very confident about my decision not to have surgery. I am also in touch with others here in my country that face the same or a similar situation (suspected ganglioglioma/DNET), they are on wait and watch as well. 

glad to talk more if you want to get in touch

best of luck

thanx a lot for your reply.
i went to the best neurological center in italy last month.
in a week and all the medical exams possible.
i'm waiting my records and files.
they said nothing had changed from 8 months ago.
but they push to resect the lgg.
is 2 to 2,5 cm big.
i really don't know what to do.
big questions
thanx a lot
ps: is there a forum or a fb group about this specific glioma?

my GG/DNET is 2.1 x 2.2cm, so similar to yours. 

why do they want/push to remove it? 

GG/DNET grow extremely slowly, if at all (Grade 1). While "true" lgg (astrocytoma, oligodendroglioma) grow much faster, even at lower grade (roughly 4mm per year). 

since yours has not grown, it reinforces the suspicion of being a benign tumor (i.e. GG or Dnet). which is of course good news. 

the challenges I see with resecting the GG/Dnet: 

- surgery may result in seizures (while I currently have none), due to scars in neural tissue / "left over" tumor etc
- temoporomesial temporal lobe is a delicate region, close to vital stuff (arteria etc), so it takes a lot of experience from surgeon
- removing hippocampus may result in memory problems
- removing amygdala may result in emotional problems (amygdala being one center of emotions in the brain)

I dont see myself taking this risk if at the moment i have zero problems, and if indeed it is a GG/Dnet. all experts I have talked to said that GG/Dnet only have to be operated if they cause seizures that cannot be treated with medication (which they typically do), NOT because of the tumor itself. Of course, without operation one cannot be 100% sure if it is a GG/Dnet. However, MRI can give good indications, and no growth can confirm the suspicion. if indeed it is a GG/DNet, likelihood is high that we have it since birth. 

anyways, I fully understand that this is a difficult decision...

they told is because im young and the outcome should be better.
they told me they take 5/6 of this surgery per month, so they are an excellence on that.
they told me they sugget but i am the one who'll take the decision. 
im going to meet another neurosurgeon i went monts ago to have other suggetsion. 
my family doctor told me to wait.
mine lgg doesn't take contrast, is not well defined and kind of bubble and cystic.
thanx for the reply
keep in touch
it was so hard found someone with the same issue and have suggetsions
thanx really a lot

i hope you are fine
i went to a neurosurgeon today (the one first suspected a ganglioglioma, and the one i asked for the second opinion)
i brought the last mr , tc etc.
he told me that:
if is a dnet i can keep on watch and wait
but if is a ganglioglioma the resection is the best option and the one in the future.
he said he can't say 100% is a ganglioglioma or dnet, based only on mri.
so im kind of confused.
im still waiting the call form the hospital i went for one week ehre i took all the exams (as they have my oldest mr etc)
it seems they are so interested in the surgery and i really dont know why.
for the first time i saw the "thing" in my brain.
and is bubbly, ike a lot of small cysts, but hey, i really can't explain it.
so now this second opinion tolm me to wait 8 months and then take the third rmi.
he told me that 8 months are not enough to understand if it grows or not . but it takes up to one year and a half.
im confused again.
thanx for the suport

hi there

thanks for the update. "bubbly" and cystic are hallmarks of DNET but cysts are also typical for Ganglioglioma (GG).

either way, most gangliogliomas are grade 1 (as are DNET), thus benign and very slow growing, if at all. 

in my case, as in the other similar cases I am aware of here in my country, neurosurgeons do not really make a difference between DNET and GG when it comes to decide between surgery vs wait & watch. 

honestly, if I were you, I would wait and get another scan as soon as useful (typically 1 year after last). if there is no growth, and you do not have any problems, it strongly suggests Grade 1 - and thus wait & watch can make sense. it is the approach I take. 

what is clear is that we have a higher risk for seizures, and of course we have to live with knowing that there is a tumor in our brain. on the other hand, surgery can result in seizures as well. 

it is confusing, i fully understand - have been there as well... 

again, IF you can live with this for another year, to then get another scan, that would be my approach. 

hope it helps

all the best to you

hello Hemsby some news.
the neuroradiologist doc from the neurological instuitute wrote me today
she told me she talked with the neurosurgeon and he told her that is for the surgery.
im really in shock  because i dont know why.

i will ocntact the neurosurgeon in the next days.
i thought that as im asymptomathic they'd wait.

Hi there


honestly, if you can I would try to relax - the most important information, I think, is that your tumor is most likely benign (DNET or Ganglioglioma). benign essentially means that it wont grow (or not much) and you will not die from this.

what this means, in my mind: 

- you have time to make your pro/contra surgery decision, esp. since it was discovered by accident and you are asymptomatic

- being "in shock" (which I 100% understand) is not a good place to make a decision - vs. wait for another year and do another MRI, and have much more time to absorb all of this

- you may have this tumor since childhood/birth - if so, why take it out now if you have no symptoms? 

it is important to remember, I think, that neurosurgeons tend to go for surgery ("in doubt, cut it out"), so take that into consideration. Neurologists are more conservative. Will be interesting to understand the WHY they suggest surgery. 

at the end of the day, it will be your decision, its your brain after all :)

keep me posted and good luck to you

thanx a lot for the reply
they waited two months for the answer.
i think they really want to cut it off to understand 100% what it is

while i know that MRI can not proof the type of tumor (nor the grade), I dont buy the logic to make 100% what it is via surgery in our case. Reason: a bubbly, cystic tumor that takes no contrast, has not grown in 8 or more months, is located in temporomesial temporal lobe (classic location of DNET/GG) AND does not cause symptoms is very likely a DNET or GG. waiting another year and doing another MRI can further help to establish this - if it does not grow, it is not a LGG (astro, oligo). if it grows, its a different story. 

just my perspective, of course. you have to be able to live with this (vs worry all the time), should you not do surgery at the moment. I find that I can very well but everyone is different...

im stil waiting to receive my file. because i took some memory test and functional mri.
the neurologist told me me in october that they are for surgery, because the outcome is better. but hey, as you told i dont have symproms. nor seizures etc.
my family dcotor is not for the surgery right now.
all the neurosurgeons are confused as i dont have symptoms.

Hi there,

I was on the internet trying to find someone who had similar and this came up so I hope you don't mind me adding to the conversation?

I had an MRI scan 4 years ago now for pain and symptoms my neuro thought could be MS, and was told I didn't have MS but FM but an incidental finding was a cystic lesion in my left temporal lobe.  It was an MRI and then with contrast and they said it looked to be benign and that I should just carry on my life and not worry about it.  Easier said than done but I do try.  They didn't give it a name but said probably there since birth, and it sounds much like this.  I saw the pictures, it is the size of a plum, so quite big, but they consider none of my problems are connected to this.

2 years ago I started getting headaches and was understandably worried as I know there is something "in there" I had another scan and was told not to worry.  Should add I am now 52.

But now I get worse headaches and sometimes my head hurts to touch, also I have breathing restriction in my left nostril.  I don't like to go back to docs and say as they always just say not to worry, but seeing on here others are still watched yearly, they never said anything like that to me and I seem to have to beg to get another test.  Would you think I would be in my right to ask for another to see as although maybe an op would not be possible, I think I would want to know and I get panic attacks that don't help.  I feel I am being paranoid if I ask again or would others out there feel the same?

Thank you

Hello Zanna

I am sorry to learn all that you have gone through. You are certainly not being paranoid. I think most of us here might feel the same. Frankly I’d go back and get reassurance on the various symptoms. I’d mention the pain to the touch and the blocked nostril. The latter may well be unrelated as you really can have more than on thing going on. You could have a sinus or have polyps problems, all of course unrelated to your earlier symptoms. Even if it all adds up to nothing, that proper reassurance will let you get on with life, without worry.

Best wishes
