Bilateral Schizencephaly

HIDE
PrevNext

0:00

This is a young child,

0:02

approximately one year of age,

0:04

who had enlarged ventricles and bilateral

0:08

schizencephalic clefts.

0:10

A shunt was placed, so you can see this

0:12

ventriculostomy catheter that goes

0:14

into this large CSF space.

0:17

And we can see a large left-sided open lip

0:20

schizencephalic cleft, or what looks like that.

0:23

We can confirm that on MRI when we confirm that

0:26

it's lined by gray matter.

0:27

And also, a right-sided schizencephalic cleft.

0:31

Once the shunt was placed,

0:34

we can see the CSF space decreased in size.

0:37

There's been decreased mass effect upon the

0:40

remaining parenchyma of the left frontal

0:43

lobe and the left occipital lobe.

0:45

Here is the MRI appearance

0:46

of the shunt apparatus.

0:48

And notice that the right-sided schizencephalic cleft,

0:51

you barely can see CSF going through it.

0:54

So this now is closer to what people would refer to

0:57

as a closed lip schizencephaly.

0:59

You can see in this patient,

1:02

there's abnormal sulcation lining the margins

1:05

of the schizencephalic cleft.

1:07

So, it's gray matter with polymicrogyria.

1:10

If we go to the right side,

1:11

we also see areas of polymicrogyria that shows

1:15

up better on this axial T1-weighted image,

1:18

where you have polymicrogyria lining this cleft.

1:21

Now, this also brings about the challenges

1:25

in pediatric imaging,

1:27

where due to their small size

1:29

and due to some movement,

1:30

even sometimes if they're getting sedated,

1:32

it can be difficult to get pristine images like

1:36

you see in a textbook on every single case.

1:38

But you don't need it.

1:40

You don't need to prolong sedation in a child to

1:43

get an image for a textbook

1:45

as long as you can make a diagnosis.

1:47

So if you know what you're looking for,

1:49

if you make your diagnosis,

1:50

all you need is images that can

1:53

help you make your diagnosis.

1:55

And so,

1:56

this patient has bilateral schizencephaly,

2:00

a large open-lipped left-sided

2:02

schizencephalic cleft,

2:03

and a very narrow open lip versus closed

2:06

lip right-sided schismus. schizencephalic
