Okay, so here we have another contrast
0:03
enhanced CT scan of the abdomen and pelvis.
0:05
And again, we're seeing some, a little bit
0:07
of consolidation here in the left lower lobe,
0:09
some tiny imperfections in this patient.
0:11
Um, we also see a bit of periportal halos
0:14
as we saw in other cases consistent with,
0:16
uh, periportal edema in this patient.
0:19
Now as we come down, we're going to
0:20
see that the liver enhances pretty
0:22
homogeneously besides that periportal edema.
0:26
But on the other side where we always look at the
0:28
spleen, you can see that the spleen is heterogeneous
0:30
here with multiple peripheral, one would say wedge
0:35
type low attenuation regions within the spleen.
0:38
That is a classic appearance of splenic infarcts.
0:42
Additionally, as we come to the
0:44
retroperitoneal location, you can see multiple
0:47
low attenuation regions within the kidneys
0:50
bilaterally in that wedge-shaped appearance.
0:52
Again, that is a beautiful
0:55
appearance of renal infarcts.
0:57
Unlike the pyelonephritis that
0:59
was kind of gray in attenuation,
1:01
chis is lack of blood flow
1:03
causing ischemic wedge type infarcts, and as a result
1:06
of it being infarcted tissue rather than normal tissue,
1:10
these are actually very low in attenuation because
1:12
there's absolutely no blood flow to these locations.
1:14
Um, this is a classic appearance
1:16
of bilateral renal infarcts.
1:19
Again, we'll go on coronal, just to give you
1:21
a better look at that wedge-shaped appearance.
1:23
I feel like that looks like an apple pie to me.
1:25
I could have it with
1:26
some whipped cream.
1:27
And on the other side we have
1:29
multiple pie pieces as well.
1:30
So this is a patient who has bilateral
1:34
renal infarcts and splenic infarcts as well.
1:37
So mostly this,
1:38
this is going to be embolic in nature.
1:40
Uh, we would look carefully at the heart in a
1:42
patient like this or suggest an echocardiogram
1:45
as a source for their showering of emboli.
1:49
You also have to hope that they aren't
1:50
embolizing to anything more vital
1:52
in their head, such as their brain.
1:55
So this is an emergent situation in this
1:57
patient, but that's also a nice imaging
2:00
example of embolic disease within the abdomen and pelvis.
