This was a seven week old.
0:02
So one week of life, former premature infant
0:05
who was born at 24
0:07
and two weeks gestational age, who came
0:10
for screening head ultrasound at Day of Life one.
0:13
So as we start with our, uh,
0:14
baby head transducer in the coronal plane going anterior
0:17
to posterior the first image, we can see
0:19
that there's gonna be an abnormality.
0:21
Uh, we have dilated ventricles.
0:23
We are a little bit off plane here, if that's okay.
0:26
We have a dilated left frontal horn, lateral ventricle.
0:29
The more striking abnormality is this very abnormal hyper
0:32
coic material, completely filling this right lateral
0:36
ventricle frontal horn.
0:38
Um, there is associated abnormal hyper genicity
0:41
of the adjacent per ventricular white matter.
0:43
Um, and it is very challenging
0:45
to see our ventricular or penal lining.
0:48
Here is, uh, a much better example
0:50
where you see this genic hemorrhage filling
0:52
and expanding this right frontal horn lateral ventricle.
0:55
We see abnormal hyper coic material in the adjacent
0:59
periventricular white matter.
1:01
We also see echogenic hemorrhagic material extending into
1:05
the third ventricle here on this coronal plane.
1:07
So this is gonna be formally known
1:10
as grade four germinal matrix hemorrhage.
1:12
Now it's more appropriately called periventricular
1:15
hemorrhagic venous infarction, so formerly known
1:18
as grade four germinal matrix hemorrhage.
1:20
Um, on this left side, it's gonna be important for us to try
1:23
to decide is there blood in this, um, left lateral ventricle
1:28
or is it, um, being squished
1:30
and entrapped by mass effect from
1:31
that dilated right-sided ventricle.
1:34
So, we'll, we'll play close attention to that
1:36
as we go through these images.
1:38
Our sonographer has measured
1:40
where she thinks the frontal horn,
1:42
right lateral ventricle ends,
1:43
and also on the left, she's me measured the anterior
1:46
horn, um, width.
1:48
Um, on the sagittal plane, we're gonna see similar findings.
1:51
And on this left side that this sonographer has labeled,
1:55
we do see some abnormal academic material in
1:57
this lateral ventricle.
1:58
So this is gonna be a left grade three germinal matrix
2:01
hemorrhage because we have genic blood in that ventricle
2:04
and we have ventricular magaly at the time of presentation.
2:08
Um, as we go to the right side to get a better look
2:10
or a different look, different plane of
2:12
that abnormal intraventricular hemorrhage
2:15
and abnormal parenchymal hemorrhage.
2:17
Um, we see similar findings as the coronal plane.
2:20
Unfortunately in this infant, this is an example
2:23
of the posterior fontella imaging.
2:25
So this stenographer took her transducer
2:28
and looked at the posterior fontella in this infant to try
2:31
to get a little bit of a better visualization
2:33
of structures posterior to the lateral ventricles.
2:36
Not gonna lie, it didn't add much,
2:38
but I thank you very much.
2:39
Sonographer. Wait.
2:42
There's an important finding
2:43
that I'm seeing on this trans mastoid view.
2:45
Looking at this cerebellum.
2:47
So this is labeled right side,
2:48
so this is gonna be right cerebellar hemisphere.
2:51
The more dependent side is gonna be the
2:52
left cerebellar hemisphere.
2:54
There is abnormal hyper coic material in
2:57
this right cerebellar
2:58
Hemisphere. So within
2:59
the parenchyma of the cerebellum itself,
3:02
the sonographer switched to the,
3:04
the hockey stick transducer,
3:05
which is a very high frequency linear transducer to try
3:08
to get a better, better look at
3:10
that right cerebellar hemisphere.
3:12
And this is very concerning for hemorrhage in
3:14
that right cerebellar hemisphere.
3:17
So posterior fossa hemorrhage is especially bad, more
3:21
so than super tentorial hemorrhage
3:22
because the posterior fossa is a small space.
3:25
And so when you have hemorrhage in your posterior fossa,
3:29
it can cause um, problems related
3:31
to mass effects on such a small confined space, more
3:35
so than super tentorial hemorrhage.
3:37
So of course, it's not good
3:38
to have periventricular hemorrhagic venous infarction.
3:41
It's also not good to have grade three germinal matrix
3:43
hemorrhage, but there's increased morbidity in mortality
3:46
when you have posterior fossa hemorrhage.
3:49
So let's confirm that on our cinematic images.
3:51
So we'll start with our linear high frequency transducer
3:54
images going from anterior to posterior.
3:58
The linear high frequency does not
4:00
give us super great detail.
4:01
So let's go to our, um, baby head transducer
4:04
to see if we can see some be, see better detail.
4:07
So on our curve, small footprint transducer, uh,
4:10
the tech clearly had, had difficulty scanning this patient.
4:14
Uh, you can see this dilated left vental horn,
4:16
lateral ventricle academic hemorrhage filled right lateral
4:19
ventricle with per ventricular hemorrhagic venous infarction
4:22
as we're going anterior to posterior.
4:24
And I did not notice this, uh,
4:26
cerebellar hemisphere my first go round through this, uh,
4:28
Corona plane series.
4:30
But you can see
4:31
that abnormal right cerebellar hemisphere hemorrhage.
4:34
Let's go to a, um, sagittal to see if we can see that, uh,
4:38
those structures better.
4:40
Here. We're going midline to the right again,
4:43
that abnormal hemorrhage within the ventricle dilated
4:45
ventricle with per ventricular hemorrhagic venous infarction
4:49
with that abnormal hyper coic cerebellum
4:52
with architectural distortion of structures.
4:55
Let's go to our, we have a syne of this, uh,
4:58
through the right mastoid fontanel, so we can see
5:03
that, uh, cerebellar abnormalities even better.
5:05
Unfortunately. So the fourth ventricle is completely a face.
5:10
There is a mass effect
5:12
of the right cerebellum towards the left.
5:15
So unfortunately this infant does have a,
5:18
an even poorer prognosis
5:19
because of the presence
5:20
of this right cerebellar hemisphere hemorrhage.
5:23
So we have poster fossa hemorrhage, right
5:27
per ventricular hemorrhagic venous infarction
5:29
and left GRE three germal matrix hemorrhage in this
5:32
unfortunate infant.
