So we'll start with our first case.
0:03
This is a 19-year-old patient who
0:04
came in with primary amenorrhea.
0:06
An outside ultrasound, which I don't have,
0:08
showed a "small uterus, no ovaries."
0:12
She was 46XX as well, just to confirm.
0:17
So we go to the MRI right here.
0:19
We have a T2-weighted image.
0:20
We have a small field of view and you
0:22
can see there's a left ovary here, fairly
0:25
normal size, lots of normal follicles.
0:27
On the right as well, we have
0:28
a normal physiologic dominant
0:30
follicle and lots of tiny follicles.
0:32
You have some tissue down here, and
0:33
then we get into the bladder, right?
0:35
Bladder's right here, rectum back here.
0:38
So vagina should be somewhere right around here.
0:43
There's your vagina, urethra,
0:44
vagina, rectum right here.
0:46
We're really not seeing any significant tissue.
0:49
We don't see a uterus.
0:51
Axial plane imaging of the uterus
0:52
is often very difficult to see.
0:54
So you're going to rely on your other
0:56
sequences, your other fields of view.
0:57
So here is your sagittal sequence.
1:00
So as we scroll through, again, you have
1:01
your bladder here, your rectum here,
1:05
kind of get them all in one plane right here.
1:07
Again, rectum here, anal canal right here,
1:09
bladder, urethra will be right in here.
1:11
That means this is the vagina right here, and we
1:13
just have this little bit of tissue right here.
1:17
And you can scroll through it to see, do you
1:18
think there's a very, very atrophic uterus
1:21
right here, or is this just all vaginal tissue?
1:24
You could have potentially a cervix,
1:26
so you're gonna look for an endometrium.
1:28
If you can see any of that or just the quality
1:30
of the tissue right here, and it all looks
1:32
very similar to the rest of the vaginal tissue.
1:34
All this sort of like mildly
1:36
T2 bright structure right here.
1:38
We don't see anything that shows a
1:40
normal uterus or cervix right here.
1:43
You can also confirm on your coronal image.
1:46
So we go backwards with your bladder right here.
1:49
Vagina should be somewhere right around here,
1:50
and this is all of your tissue right here.
1:53
And now we're all the way back into the rectum.
1:55
Again, some free fluid back
1:56
here, which is physiologic.
1:57
But here's your vaginal tissue right here.
1:59
So this is all just vaginal tissue.
2:01
Almost looks like a hysterectomy in that sense
2:03
where you have this vaginal tissue there.
2:05
So this is considered a hypoplasia right here.
2:09
So we see hypoplastic vaginal tissue.
2:11
We see lots of parametrial vessels.
2:13
That's what all of these are right here.
2:17
And we see our normal ovaries.
2:20
In her particular case, we did do some
2:22
imaging on the T2 of the abdomen to see
2:26
if she had kidneys, and you can see here
2:28
that she does have two kidneys normally
2:29
positioned and look pretty normal.
2:32
No anomalies there.
2:34
So what happens here, this can occur
2:36
because of an interruption of mullerian
2:38
duct development very early in development.
2:40
You can get a complete aplasia, or you
2:43
can get a hypoplasia, and that can include
2:45
the vagina, the cervix, or the uterus.
2:47
So in this case, our patient has
2:48
a vagina, but no cervix or uterus.
2:51
So obviously this patient will not
2:53
be able to carry a pregnancy to term.
2:56
She could have a surrogate potentially because
2:57
she does have ovaries, so she can have a
3:00
surrogate, but there won't be a pregnancy.
3:03
There's nothing you can do about that.
3:05
So in cases like this too, beyond
3:06
that, the goal is also to enable sexual
3:09
function if the vagina itself is affected.
3:11
And in her case, it is not.
