For moving right along here.
0:03
And we'll go from easier cases to harder cases. So here's a
0:06
sort of Mystery Case for you. Let me
0:09
start at the top and I'll scroll through this case.
0:17
And I'll open the poll questions now. So
0:20
what do you think the most significant abnormality
0:23
is here almost to the side and I'll keep scrolling.
0:31
If you just a few more seconds just finish answering.
0:35
All right, let's close the poll and see what people thought.
0:41
All right, and I'm curious. So some people
0:44
said the septum and other people
0:47
said The myocardium, so let's take a look and see I am
0:50
try to guess what people are going to say on
0:53
these cases so I can understand people said septum
0:56
because I I believe that they perceive that the septum here
1:00
is is thin or perhaps you can't see a septum
1:03
but I can tell you if this were a
1:06
big ASD one thing that usually see with that big of
1:09
an AST is Right hard and enlargement which we don't see right there.
1:12
So the symptom is really there. There's no ASD the persons
1:15
who said Mike hurting them are correct. So, let's see
1:18
what the findings. Are. You see low attenuation Foci
1:21
in The myocardium of the left ventricle,
1:24
especially at the left ventricular Apex.
1:27
And you can see that this is so low attenuation. It looks a
1:30
lot like fat. In fact, it is fat.
1:32
However, the mycardium is not really very
1:35
thin. It's sort of normal thickness my cardium.
1:38
I can show you that here. So the question is are these
1:42
old infirks like we see almost every
1:45
day where we see fat fatty metaplasia
1:48
of the left ventricle from inferks. Well, no,
1:51
these are multiple territories. It
1:54
doesn't really confine itself too. I've asked
1:57
for territory also, it's very globular. So
2:00
when is the last time you've seen an inference look like that look like
2:03
a blob of fat and furthermore,
2:06
although some of these areas are some endocardial
2:09
which in Forks old and
2:12
forks. Love to give you others are actually some epicardial
2:15
and midwal like this.
2:18
So that's not typical for old inference.
2:21
Now, what could this be? This could
2:24
be a couple different things if I told you this patient had tubers for
2:27
Roses. Well two sclerosis is famous
2:30
for producing the so-called inter.
2:32
Cardial fatty Foci, which can look
2:35
like this you can just get fatty deposition within the
2:38
heart also, you can get fatty deposition within
2:41
the heart with just aging but that tends to
2:44
involve the heart diffusely. It tends to be patchy tends to
2:48
involve the right ventricle a lot as well as the left ventricle intense not
2:51
to be as focal as this
2:54
So let me show you and Mr. Of this patient
2:57
and let's go to the next series here. So the
3:01
Mr. Here if you're not a cardiac imager, you're
3:04
not you may not be used to looking at this but this is a
3:07
short axis view. We're looking at a slice right through the
3:10
heart here and you can see that the
3:13
normal myocardium is going to be dark and
3:16
this is so called an old myocardium and the the
3:19
hyperintense area here. This is
3:22
after we've injected Galilean and waited about
3:25
10 minutes. So this is late abnormal Catalina
3:28
in enhancement. You can see that their focal globular areas
3:31
of enhancement here in the left ventricle and
3:34
scanning on down you see it particularly at the Apex a lot
3:37
of enhancement of the left ventricle. I can
3:40
go to the next series here and show you even more of
3:43
this enhancement. So you can see now we're
3:46
looking at the left ventricle along the long
3:49
access here. You can see a lot of enhancement globular enhancement
3:52
and this is not a Vas.
3:54
Territory, this is actually patient with myocarditis and myocarditis.
3:57
Although we don't see it every day on
4:00
non-gated CT do this. It's one
4:03
of the things that when it is is burned
4:06
out so to speak it can leave areas of
4:09
fatty amount of plasia within the heart within
4:12
especially the left ventricle. So when you
4:15
see nonvascular territory fat like this one of the
4:18
things that you may want to think about is another insult
4:21
that the patient may have had like a myocarditis or
4:24
even a burnout sarcoidosis could also
4:27
have this appearance. Although have to say I've never seen a sarcoidosis
4:31
do this. I have seen my cardio. Myocarditis do
4:34
this several times. So so a nice case of
4:37
fatty replacement of areas of the left ventricle due
4:40
to a prior my carditis.
