alright, so now
0:03
another young gentleman 26 year old male right up
0:06
a quadrant pain. And this was interesting in that the patient got
0:09
a I'll just tell you the history got a CAT scan showing no real
0:12
abnormality that got an ultrasound where they couldn't find
0:15
the gallbladder. They got a Hiatus scan that showed no
0:18
uptake in the gallbladder. And so they were like
0:21
well, you know worried about cholecystitis potentially,
0:24
but because there's
0:27
no uptake in the gallbladder, but the or potentially,
0:30
you know, the gallbladder was just absent but
0:33
there's no history of Prior Kohl's hystectomy. So they got another Imaging modality
0:36
to sort of sort this out and that's what I'll share with a group.
0:39
Somebody's asking why renal Pharaoh in the right? Kidney is
0:42
working perfectly. I think that I miss
0:46
you. I'm not really sure to be honest. I think I was just a history that was provided.
0:49
I think oftentimes we get these generic histories, but they certainly
0:53
were not this is the second case. Yes, somebody's
0:56
asking but certainly perhaps a
0:59
left kidney was dysfunctional enough that it was affecting
1:02
the overall renal function in the patient.
1:04
So let me show the second case. It's an MR a few
1:07
more sequences to look at and I'm happy to you know, scroll through some selected sequences
1:10
and I'm happy to scroll through more
1:13
of the group once okay, so I'll start up with the t2fatsat sequence. Remember, this
1:16
is a young patient right upper quadrant pain HIDA scan
1:19
showed no uptake in the gallbladder, but, you know,
1:22
they weren't really worried about clinically about cholecystitis.
1:25
But person also never had a cholecystectomy. So they're
1:28
just wondering
1:29
What's going on with the gallbladder? What's going on in this patient? So here's
1:32
the
1:35
t2fatsat sequence
1:44
Right, you can see a bunch of organs here spleen kidneys
1:47
adrenal glands.
1:50
Probably just sort of hone your eyes to the
1:53
sorts of things that you may be worried about given this.
1:56
History is the coronal T2 image.
2:07
And I'll show you a myth of the MRCP that
2:10
helps at all.
2:14
These images didn't come out too. Great. I'd imagine so I'm not sure
2:17
this will help you but let's look at the
2:20
Excuse me, the T1 pre.
2:24
- let's give
2:29
you a post contrast sequence in the arterial phasers. Look gonna
2:32
be a little bit of motion here. So
2:37
I'll say that I not sure if the motion
2:40
will affect.
2:43
Don't think it should affect your interpretation of.
2:46
What's going on? There's no mass or anything that I'm asking
2:49
you to characterize. It's just this is probably the best sequence the
2:52
portalena's face.
2:54
Got some of the other organs again.
3:06
So the question they're really asking is you know, what what's going
3:09
all the gallbladder that inflamed. Is it
3:12
missing? He's had no prior history cholecystectomy.
3:20
I see a few.
3:24
People in the chat box. I'm just gonna address that in the second
3:27
while I go through the final set of sequences. I wanted to share with the group is the in and
3:30
out of phase out of face on this side and face on this side.
3:34
All right,
3:42
there you have it. So I'm just going to put up.
3:45
Let's see.
3:48
Go back
3:51
to this box here. Okay, let's see we have here. Yeah, so
3:55
somebody describe that there are multiple pancreatic
3:58
system. So that is a good observation. It's a
4:01
correct observation as well. It's a maybe useful
4:04
observation scleros and colonitis. Okay can
4:07
generally absent golf better. You know, I suppose that can happen.
4:11
I yeah anything can be continually absent. I
4:14
haven't really seen a case of that but I'm sure
4:17
if I go to radiopedia, it's there fatty liver. That's another correct
4:20
observation. I don't see a call platter. Yeah, that's that's that's
4:24
absolutely correct David. That's that's the tough part here.
4:27
Is it there is it really really small app since missing gallbladder? Yeah
4:30
cystic duct obstructive Stone.
4:32
Okay. So a lot of good thoughts portal means a
4:35
little dilated. Let's look at that observation day. Do you
4:38
remember being a little bit big?
4:40
Yeah, it looks a little bit big. I don't know if it's
4:44
maybe a little bit bigger than normal. I agree with you. I'm not
4:47
sure if it's pathologically big but the
4:50
question I have for group is is that the one thing I'm sort
4:53
of emitting obviously here is that
4:56
MRP again? I'll show that the one thing I'm admitting from
4:59
the group.
5:00
is that
5:03
The patient has some underlying history. There's an underlying.
5:07
History that this patient has that I haven't given the group.
5:10
but that
5:13
disease into that rare disease entity as it were.
5:16
all sort of put together
5:18
Couple of observations that the group is made. Somebody asked us
5:21
closingitis. I think it's a good thought my own experience
5:24
perhaps it's just with some of the mrtps that we get. It's a little bit tough on
5:27
the mrsp to look for that. I like to look at those on the post contrast sequences.
5:30
And what I'm looking for is areas of
5:33
ductal dilatation and narrowing which
5:36
is strictures and on the post Contour sequences bile will
5:39
be dark as it contains fluid. And so you'll see areas of biliary
5:42
reductibilitation and then you won't see that bile duct and then you'll see it
5:45
again as it dilates and you won't see that bottled up and so you sort of have these alternating areas
5:48
or multifocal and so if you
5:51
just look at you know that, you know, the the post Contra
5:54
sequences which are thinner slices you really don't
5:57
see any ducks that are dilated nor do you see a CBD that's dramatically affected
6:00
and so I was one of the thoughts of somebody in
6:03
the group had but
6:05
You know, I don't know if I see convincing evidence of that based on
6:08
these images. And so
6:11
let me see the chat feature. Where is the group going?
6:15
Okay, here we go. Here we go congenital absence
6:18
missing gallbladder bronze diabetes.
6:21
Oh, I haven't heard that term in
6:24
a long time. Thank you for igniting some
6:27
some memories there. Some Ron
6:30
is asking about cystic fibrosis which seems to be out there. But I appreciate them
6:34
putting themselves
6:37
with that diagnosis a true
6:40
eight. Try to get topic gallbladder. Okay PSC static
6:43
fibrosis Colonial position gallbladder
6:46
over long CBD PSC also going
6:49
to be pancreasics CFT are okay. Okay. So
6:52
yeah, this is nice. I I like that
6:55
people are starting to not only
6:59
get warmer trying to figure
7:02
out the disease is that they've absolutely nailed it
7:05
and so I won't torture the group anymore. Thank you for your
7:08
engagement. Ladies and gentlemen, this is
7:11
a case of cystic fibrosis is what the patient had and the reason
7:14
I wanted to
7:15
With the group is you know, listen, you know, you
7:18
know in our in our patient population, you know, we we do see cystic fibrosive time
7:21
in the classic case that we all see that we all
7:24
show in sort of case conferences of that fatty atrophic, you
7:27
know, the fatty pancreas the absence of the pancreas and I'm sure
7:30
if I showed you that case you guys would be you know, why why did
7:33
I even tune into the seminar?
7:35
I know that I know that day in and out
7:38
one thing that
7:40
that I learned a little bit later on in my training was the
7:43
you know, the other manifestations of
7:46
cystic fibrosis in the abdomen and pulse and that
7:49
sort of is always interesting and it's almost now I look for those
7:52
manifestations because the ones that we see all the time are so
7:55
burned in my memory and one of the things you can see is
7:58
multiple multiple pancreatic cysts. They're diffused
8:01
just like here and it's thought to beat
8:04
you to inspipated secretions, which dilate the Ducks these are not
8:07
neoplastic. This person will not develop cancer as
8:10
a result of these cysts, but you can see it best on the t2 aided
8:13
sequence multiple multiple systems the first comment that I think somebody
8:16
made which is good for you to recognize that and you
8:19
know, you can certainly see cysts like
8:22
this, you know in other conditions but you know,
8:25
maybe in chronic pancreatitis you can multiple times but the
8:28
pancreas there is very very trophy in those instances. And so
8:31
that's one of the manifestation to cystic fibrosis is
8:34
something called pancreatic cystosis, and you can
8:37
also sometimes get some calcifications so it can
8:40
look like
8:40
Pancreatitis so that sometimes gets confusing that's even
8:43
rare. But when you see these cyst, that's what you
8:46
have to think about. Well, the other things that patients with cystic fibrosis can
8:49
get in the abdomen is hepatocytosis, but that
8:52
itself is not
8:54
You know, is that an important finding because
8:57
we see that in our patient population all the time, but certainly this
9:00
patient has hepatic stytosis. So that's that's not subtle and
9:03
then the final question which I think is the most
9:06
unfair question. But but there
9:10
it is is where is the gallbladder? Right
9:13
and so I think a few people say can generally absent Gall better. I'm sure
9:17
that exists and and certainly that's
9:20
something that I would have thought about if I'm scrolling in the setting but if
9:23
you know a little bit about cystic fibrosis, you'll
9:26
know that there are some call that automatic stations of cystic
9:29
fibrosis one of which is for some reason this really one
9:32
of my favorite entities is micro micro gallbladder.
9:35
So I think some people in the chat box had a
9:38
credit gallbladder and I think the term is micro gallbladder, but
9:41
I tried it is very reasonable. So my goal here is to find the
9:44
gallbladder and believe it or not. This is the only sequence which I could find it right over
9:48
here is your gallbladder.
9:50
It's small. There's nothing else. This is going to be it's not a loop
9:53
of bowel. It's not a bile duct. It's right with a gallbladder should
9:56
be and it's really small. It's micro. In fact, you know,
9:59
and I looked up the definition of micro gallbladder
10:02
because I'm sure there are people in the in the group that
10:06
They'll want to know about Michael. You
10:09
know, how do you define it? And you know, I think
10:12
a ballpark number that I looked at I think is easier
10:15
to remember is like two centimeters in width by one centimeter in in
10:18
transverse time it two centimeters in length
10:21
by one centimeters in transverse diameter to be honest.
10:24
I'm not going about measuring these call patterns, but we all have a sense of
10:27
what a normal gallbladder. Perhaps should look like even if
10:30
it's collapsed.
10:31
This is Tiny. And so this patientistic
10:34
so is in fact it's you know, knowing that
10:37
we're not surprised that we couldn't even see
10:40
any uptake in the gallbladder. Some of the inspected secretions. I think somebody's
10:43
talked about that the chat box will contribute to
10:47
to the micro gallbladder. Maybe that's the theory of why it's
10:50
very small but even it, you know, even if there was uptake in
10:53
this, you know, good luck perhaps finding that
10:56
in the context of the highest scan or even an ultrasound think it'd be very tough and it
10:59
was very tough on the CT. I happen to read the CT on
11:02
this patient. I do remember seeing it and and mentioning my report micro
11:05
gallbladder because it's just one of those manifestations that
11:08
you can see assistive and there are others in
11:11
the admin politics you get distill intestinal obstructive syndrome. They can
11:14
have also issues with the stamina vesicles and males and so this
11:17
was a case of cystic fibrosis to
11:20
the micro gallbladder.
11:21
And so let me share this this slide
11:24
with you to for a few
11:27
words about cystic fibrosis autosomal recessive and one of the things
11:30
that I think it's important for us to know about these other manifestations Beyond
11:33
say the chest and the nor in a
11:36
and the most common manifestations in other organs is that you know, we've
11:39
had better.
11:40
Treatment algorithms for patientistic fibrosis. And
11:43
so these patients are surviving longer and so you end
11:46
up seeing you know, you will in Time end up seeing more different
11:49
manifestations of that. We don't that we
11:52
haven't traditionally seen and in the pancreas of course
11:55
fatty replacement is the most common but you can see these cysts
11:58
for the reason that was that I mentioned they're
12:01
very small. They replace the pancreas the San
12:04
Diego pancreatic cystosis. You can sometimes also see califications
12:07
and that's thought to be some data abnormal physiological that
12:11
promotes calcium binding
12:13
and so these patients don't have chronic pancreatitis. It's
12:16
just calcifications a tiny calcification associated with
12:20
Cystic fibrosis stewtosis, you can see up to 50% of
12:23
patients. So that's pretty obvious. You look at the endophase images and
12:26
the micro golf. I look at that almost a third that's not
12:29
an uncommon amount. I suppose, you know, and so
12:32
and thought to be either Treaty of the cystic
12:35
doctor chronic stenosis and something to do with the way the
12:38
secretions are manifested in these patients. A lot
12:42
of people mentioned PSE they can get PSC type picture in
12:45
in their Ducks. This person did not have that but that's a
12:48
possibility. So I think it's a good thing to look for and of
12:51
course another organs in the battle. They can
12:54
get distal intestinal obstructions in your ass to look at that from time to
12:57
time. Would you this top? I'm not sure if this
13:00
helps even an impatience that's one of the questions that are being
13:03
asked I find that even with patients in normal gallbladders
13:06
is very seldom that I see the gold or filling up really nicely. It
13:09
might help in the sense that it you
13:12
have this will increase the background the signal
13:16
intensity of the liver prank. And so maybe you see a small
13:19
sort of
13:20
micro gallbladder the gallbladder fossa as
13:23
a dark signal amidst the variety of list
13:26
Haida. In fact was done in this case that one of the other panelists people
13:29
are asking about Ida it
13:32
was actually done in this case. They didn't see the gallbladder.
13:34
And so my end of one based on this case was suggest
13:37
that the height I would not help or at least it did not help in this case.
