Does anyone have a Dnet brain tumour?

Hi everyone, I’m new to the group and wanted to introduce myself. My name is Lisa and I have had  an intruder since 2020.

I’m 49 and was diagnosed with a suspected DNET brain tumour following a long and quite stressful diagnostic journey. They can’t say 100% it’s a DNET because they don’t want to do a biopsy due to the location, so I’m currently on a watch-and-wait pathway with regular scans.

I’ve been told this tumour wasn’t present in childhood, which I understand is unusual for DNETs, and I’ve never had epileptic seizures, which again seems less common. What’s worrying for me is that it is growing slowly each year, even though surgery isn’t currently recommended.

Alongside this, I also have IIH, and I’m finding the combination of symptoms, uncertainty, and monitoring really challenging at times. I struggle with health anxiety, especially around scan results and the “wait and see” approach.

I wanted to ask:

Does anyone else here have a DNET, particularly diagnosed in adulthood?

What symptoms do people have apart from Epilepsy? 

Has anyone been on watch-and-wait with gradual growth?

How do you cope with the anxiety and uncertainty that comes with this?

Anyone using alternative therapies? 

I’d really appreciate hearing from anyone with similar experiences. Thank you for reading Blue heart

  • Hi Lisa 

    Yes it hards. 

    I aim to continue to eat healthy and get out and about as soon as possible after the surgery.

    My daughter was in the away last week. She was cancel on holiday.  I did no to cancel her the lose the trip because of me was in the surgery  I was home in 3 days,amazing. 

    She is come there to night and at the nextt GP account  on Friday and behold.

  • I hope you recover well. That's a fantastic picture. 

  • Hi,

    Yes, I have what is a possible DNet in he Glioneuronal Tumour family.

    I'm 52 now and was diagnosed just over 3 years ago after experiencing 'episodes' similar to seizures I had as a child.  Had an MRI and there it was, a tumour that they think I was born with and was the cause of the seizures when I was a kid.

    I've taken medication that controls the seizures for 40 odd years (apart from the blip a few years ago).

    In terms of the scan, I've had one every 3 months, 6 months and 18 months since I was diagnosed.  The latest one was earlier this month and it has grown by 6mm since 2024.  I'm not bothered as my feeling is that it has been there all my life, it's a grade 1 and grows slowly.  But because there has been growth, I have gone back to six months between scans.

    I've learnt to cope with it and regardless of how much it grows, my view is that providing it doesn't cause me any problems I just try not to think about it.  It was horrible when I first got diagnosed but I still hate scans and all the anxiety that goes with waiting for results!

    Hope that helps!

  • Thank you so much for replying — it really does help to hear from someone with a similar type of tumour and on a similar pathway.

    I do feel very lucky that I’ve never had seizures, and I remind myself of that often. At the same time though, I’ll be honest — sometimes that then makes me question whether the diagnosis is the right one, especially as DNETs are so often linked with epilepsy. It really messes with your head and adds another layer of uncertainty to an already uncertain situation.

    Like you, I’m finding that knowing it’s growing slowly but still being managed conservatively is one of the hardest things to get used to. Hearing how you’ve learned to live alongside it, rather than letting it dominate everything, gives me some reassurance that this gets easier with time.

    Scan anxiety is definitely something I struggle with too — I don’t think that ever fully goes away, even when you’re told it’s low grade and slow growing. It does help knowing I’m not alone in feeling like that.

    Thank you again for sharing your experience. It really means a lot and has helped me feel less isolated.

    Wishing you all the best with your ongoing scans and monitoring.
