This was a one day old infant who, uh,
0:03
underwent screening spine ultrasound
0:05
for multiple congenital anomalies.
0:07
This patient had esophageal atresia
0:10
and so there was concern for ral malformation,
0:13
so vertebral body anomalies, anorectal malformation,
0:17
cardiac anomalies.
0:18
The T is tra esophageal fistula,
0:20
which this patient had the esophageal
0:22
atresia version of that.
0:24
Um, and then limb abnormalities is the l.
0:27
So we are presented
0:28
with this spine ultrasound in this one day old infant.
0:31
So we are imaging with our linear high frequency transducer.
0:34
This infant is in the prone position
0:37
and we are starting in the longitudinal or sagittal plane,
0:40
and we can see vertebral bodies
0:42
and intervertebral disc spaces anteriorly.
0:45
We see posterior elements at the, uh,
0:48
at the superficial aspect of the screen
0:50
because we are imaging from a posterior approach.
0:52
And then here is our spinal cord
0:54
and our spinal canal contents
0:56
with a nice normal looking cord.
0:58
Nice, normal, uh, looking central app penal canal
1:00
and nice normal looking anaco CSF at the dorsal
1:04
and ventral aspects of this cord.
1:06
As we go inferiorly though, we're going to, uh,
1:08
pay close attention to the morphology of our conus meis.
1:12
We're gonna look at where are thecal sac ends,
1:15
and we're gonna look at our phylum terminality.
1:18
So when we're trying to guess,
1:19
or trying to label appropriately the levels
1:22
of the vertebral bodies,
1:23
we're gonna in our mind's eye draw a line parallel
1:26
to the lumbar spine vertebral bodies.
1:28
We're gonna draw a line parallel
1:30
to the sacral vertebral bodies
1:32
and where they intersect is going to be L five S one.
1:35
So this is L five. This is S one
1:37
as a confirmatory thing we can do in this patient is the
1:40
thecal sac should end at the S two vertebral body.
1:44
So this is, uh, confirming
1:46
that this vertebral body is S two.
1:47
So S two sacral two, sacral one L five vertebral body,
1:52
L four vertebral body n conus meis.
1:54
It extends all the way to the L four vertebral body.
1:58
Not only that, this is our phylum terminality
2:01
and this looks just a little bit thick to me.
2:03
Um, I don't see it measured, um, by our stenographer,
2:06
but this is gonna be an abnormal, uh, lumbar spine, uh,
2:10
abnormal position of the conus mellis
2:12
concerning for tethered cord.
2:14
So this patient will go on to MRI.
2:18
So the t here is showing us
2:19
that the coil segments are un ossified.
2:22
We have normal, rectangular
2:23
or square shapes of our sacral vertebral bodies.
2:26
This is L five and again, our conus meis,
2:29
we can see at the superior aspect
2:31
of the screen here extends all the way to L four.
2:33
So this is a low line conus meis.
2:36
Um, we don't see evidence of a presacral mass, so don't,
2:40
just don't forget to look at your vertebral bodies,
2:42
look at the spinal cord contents, look at your, uh,
2:45
coil segments, but also look at the rectum
2:48
and see if there's any sort
2:49
of abnormal heterogeneous mass in this infant.
2:51
Especially in an infant with multiple congenital anomalies.
2:54
You don't wanna miss a presacral mass, um,
2:57
coexisting at the same time.
2:59
Our tech has labeled the levels for us.
3:01
Thank you stenographer. So this uh, spin is process.
3:04
They have labeled as L three.
3:06
So this is the L three vertebral body. This is L four.
3:08
So they're counting matches our counting
3:11
with this conus mellis extending all the way
3:13
to the L four vertebral body.
3:15
We're gonna look at our motion next.
3:19
So on this cinematic image, uh, normally the nerve rootlets
3:23
of the coquina
3:24
and the conus midis move nice with, uh, respiratory motion
3:28
with cardiac pulsations.
3:30
And this just looks stuck.
3:31
There's not a ton of movement of these nerve rootlets
3:35
of the coquina surrounding this lowly conus meis.
3:39
Um, this phylum terminology on the syn image doesn't look
3:41
particularly thick, but it's not moving.
3:44
So this is concerning for, um, lowly conus meis.
3:48
So concerning for tethered cord, this patient will go on
3:52
to lumbar spine, uh, screening
3:54
or, uh, this patient will go on to follow up spine MRI
3:59
to confirm findings and for preoperative planning.
