There are 10mm to each centimeter; therefore, a mm is definitely smaller than a centimeter. (A centimeter is slightly less than 1/2 inch.) Annies are usually measured in mm, however, I have heard of some measured in centimeters when they get to the "giant" size. I don't know of equivalent measurements like you are asking, but someone else may. If you look at your standard ruler, the cm with the mm are on the opposite side of the inches. I used to just measure it out on a paper and draw a circle around the dimensions to get an approx. idea of the size of mine, and also used the mm to determine the neck size.

Thanks or the information. I saw the ruler comparisons, however in the different sites, 1 said centimeter is bigger and the other said millimeter is bigger

My GF just found out she has a tumor around 5 millimeters but described it as the size of a persons hand. She is upset and I didn't know what to say but felt she may be confused on MM vs CM's.

Drawing the circle is a great idea. I happen to have my aneursym CD so I can actually see it pre-op.

I can't remember if mine was 7.5 cm or 7.5 mm. I only remember the 7.5.

Thanks again.

Well, then her tumor is exactly 1/2 centimeter--about the size of a baby pea in my estimation. Yours must have been 7.5 mm (exactly like mine) because 7.5 cm would definitely be the width of an average woman's hand and that is huge!

I just spoke with my GF and she has a 5.2 cm pancoast tumor. She had a port inserted this morning and will have radiation, then chemo. They will try to shrink it and then surgically remove it.

It was her husband whom told my husband that it was the size of a hands fist. He must have been in a panic mode.

I pulled my aneurysm report out and mine was 7.5 and I was told that it was the size that most ani's have a tendancy to burst at or grow bigger. So right the and there I had mine clipped without even thinking about it. My feeling was either fix it or have a stroke just worrying about it growing. To much stress to NOT have it repaired.

Now in what you said that it is big or did I misunderstand you? Because I have my MRI & Cat Scan CD's and in looking at it pre-op it looks like its about 1/2" or less, def not the size of a fist.

I did look up my GF's tumor and just not sure about the prognosis of it especially because its malignant. She said the doctor said its curable and good prognosis. Either they do not want to tell her the seriousness of it "yet" or the info online is wrong. They will remove it once the radiation & chemo is completed.

All we can do is pray for all of us going through these awful conditions and hope for the best. Any type of growth in any part of a body is a scary, stressful situation to be in.

Good luck to her. That is large, but then again we are talking about a tumor and not an aneurysm. I stated that both yours and mine (annies) were about the same size at 7.5 mm (not cm). If they had been centimeters, well then that would have been a real problem! It makes sense that they want to shrink her tumor before removing it surgically. Anyhow, I wish the best outcome for your friend. Take care, Patty

When I was in ICU, one of the nurses said my aneurysm was 12.5 cm, partner wanted confirmation and a doctor said 12.5 mm. It is important to know the difference, the rule of ten, etc

Oh I just thought of something…see if you or your husband has a drill bit gauge. Now days the cheap ones are plastic with holes and measurements in mm or fractions or decimals. They are used to figure out the thickness of a drill bit or screw or nail. Some will have a ruler along the sides, one metric, the other standard. It might give you a better idea of size. Some are a set with metric and standard on different plates. Though I really like Patty’s idea since you can draw it out quickly and put the neck in. Thanks for the idea Patty!

And here’s a great explaination of m, cm, mm (I like woodworking) and it may be where the confusion started Jeanne. If you need more you may want to try googling for objects or pictures in the measurement you wish to know.

Thank you all for sharing data on this...yes, I knew how to pull it up online...but had such difficulty "remembering" the basics... and, always have to look again in the time frames...and, will be noting the (of record) on some imaging...w/the conversion to inches...our basic /average comprehension of size...

Now my next interest...is in the portion of that measurement...and, for which shape...the most average saccular...aka "berry" shape?

My diagnosis, off L ICA @ PCOM branch was:

3-4mm neck X width on ICA - not length to aneurysm body

5 mm from its neck to base of aneurysm

7 mm length?) distance from side to side...seems that size/shape likely relates

to the structures and/or gray and/or white matter / other

arteries ...and, how those allow an aneurysm to form its shape ?

OR does the pressure of those tiny bulging / expanding

aneurysms re-shape the structures and white/gray matters?

My mentality "pictured the 5 and 7 in reverse...tho the image shows it clearly in its shape I listed...

I’m not sure what the measurements relate to as we were told one size, my chart has the two sizes and unfortunately I won’t see my doc for a year… I will see if I can find the answer. I also wonder if they measure mine from the most outer lobes (I had a multi lobed aneurysm) or just the saccular part minus the lobes?

Found another website...(12 years for me!) if I ever read it before I have no memory of it...or notes in my Word program...I have learned to browse my own stored data!

The reason noted here ...is that they reference "one size"...by mm's...and do equate to inch fractions...

but they do not (same as other sites) qualify which direction they are measuring...one of these days when I post my "natural" aneurysm image(s)... I can suggest why I get so confused on "sizing"...of a natural saccular aneurysm...

And, as I sit here typing...comparing it to a balloon...I have to concentrate (re-learn)...whether they need to be qualified ...."round" or "oblong"...or whatever...

That is here my confusion comes in...when we are told one 'size'....and, then some records note the varied portions...

I found only the diameter of the aneurysm being measured by several sites. I can’t honestly say if they are measuring neck and height and which order those are in the equation. So maybe neck x diameter x height or diameter x height without neck measurement or perhaps the three measurements are from 3D pictures which then would equate to diameter x height x depth.

Moltroub...thanks...there are more issues....to/of which we do not get basic data provided by/thru the hellth care industry... the sizing is as confusing as to why the aortic arch has not been explained...when it is the parent of the three main arteries...feeding thru our neck and into our brain... will provide some more on that later on..

I failed to proof my website typing above... so here it is again...hope it is right
