AIBU to ask whether anyone knows much about adrenal lesions?

[JetTail]

Specifically interpretation of Hounslow measurements and washout figures?

Probably the biggest long-shot ever taken on Mumsnet lol

Measurements are calculated on CT scans.

CT without contrast: a low density nodule, 10HU, then do a CT with contrast (1) measure density (2) wait 15 min and re-measure.
Calculate the %change in density - the actual calculation with depend on whether the CT without contrast is available
(not unusual for a nodule to be identified incidentally for the first time on a CT after contrast has been given as this is usually how scans are done).
There are % cut-off for a benign nodule.

Hope the long shot helped

It has helped in that I can tell that you know what you're talking about .
They did without and with contrast (CT) having only picked up on its presence accidentally a year ago and then, only having noticed it after an MDT as initial CT results didn't show it - they weren't looking for it lol.

However, the results appear to be a little contradictory.

If I give you the measurements, as they also mention the 'washout' percentages, would you be able to interpret what it's saying? Anything I can find online in terms of explanations uses different terms to those written by the consultant.

Thank you very much for your reply. It seems to be an obscure area of medicine as my doctor friend has never heard of Hounslow lol.

I have absolutely nothing helpful to add, but I mis-read your title as adrenal lesbians. I wondered what was so special about the adrenal glands of lesbians.

I hope you are well, and the adrenal lesions aren't anything untreatable.

It's small (1.7 cm) on left adrenal and is stable and doesn't appear to be producing anything - apart from bafflement in me lol. However, from my interpretation of a medical-type thing which I found on google, the results of the CT measurements, ie density and washout, suggest something other than benign.

This is the article I read.
www.ncbi.nlm.nih.gov/pmc/articles/PMC4448636/

However, the figures in the report, don't really correspond to the terms used in this article.

PMSL!!! Lol.

And what are the odds of a mumsnetter having heard of Hounslow and also having come across this thread! Honestly, I prefer Mumsnet rather than google as there is always one mumsnetter who knows shit!!! Well, there are a lot who think that they know shit too but I really didn't think anyone would reply.

I'm not sure whether you get informed when your response has been quoted, so to cover all bases, I'm going to @ you @Coffeewinecake

Results as follows:
'She had a CT of adrenal with contrast on 9th of March. This showed indeterminate 1.7 centimetre nodule in the left adrenal with baseline density of 26 Hounsfield with 58 Hounsfield in portal venous phase and 41 enhanced within the delayed phase. The absolute washout was 53% and relative washout 25%. However the nodule has remained stable from the scan on 1st of February 2021 to the current scan'

It might have helped had I referred to Hounsfield rather than Hounslow in my OP. I'm sure Hounslow has done something noteworthy in his life too, but Hounsfield is the dude involved in this discussion

Just bumping after the weekend in the event that anyone knows anything about the above i.e. Hounsfield measurements, not Hounslow.
Thank you!

Apologies for the delay @JetTail

The % washouts have been calculated correctly and make he adrenal indeterminate.

If the absolute washout had been >60% (or relative washout >40%) then they could pretty confidently state it is a benign lesion.

I must stress that the adrenal nodule may sill be benign and it’s good that it has been stable for the past year.
Context will be relevant.

HTH

Thank you - It's pretty much the conclusion that I came to also after reading the article I linked about 20 times. It's a bit of a contradiction, in terms of the results they're finding. The frustration is that I haven't had any follow-up arranged and the consultant endocrinologist will discuss whether further imaging is required at the next Adrenal MDT. Who knew such a thing existed! And I have no idea how often such events take place. So I shall remain in limbo, googling lol.

It’s good that it will be discussed at the adrenal MDT - you will get a consensus o expert opinion (physicians, surgeons, radiologists and pathologists).
The endocrinologist should contact you to discuss the results. MDT frequency can vary from weekly to monthly.
I would it give it a couple of weeks (which I appreciate will feel like an eternity) and contact their secretary if you still haven’t heard anything.

I'll just have to wait I guess! Thanks for your help.
