Sciatic Neuropathy

HIDE
PrevNext

0:00

So this is my, this is the last case,

0:03

a 20-year-old female amateur,

0:06

MMMA fighter, uh, foot drop.

0:08

After five days of intense kick training session,

0:12

her coach kicked her post posterior, uh, upper tight a lot,

0:18

and like, let me show you the images of this case.

0:23

So here are the images of the, of this case.

0:27

Let's start with the this T two with fat saturation.

0:31

And we can see right here look that this is the left,

0:36

the right sciatic nerve.

0:37

This is the left sciatic nerve.

0:40

Look, the size and the signal of the sciatic nerve.

0:45

It's total, it's totally different.

0:47

The left SCIA nerve, it has a, it is, it's bigger,

0:52

it's larger, and it has a right signal,

0:55

a high signal in comparison with the other size,

0:59

with the right size.

1:00

So this is, uh, neuropathy of the sciatica nerve,

1:05

uh, due to this, uh, training session

1:09

with the direct trauma, chronic direct trauma, uh,

1:13

at the sciatic nerve, uh, close to the, to the

1:18

tuberosity right here.

1:20

So this is the, so this is the T two

1:23

XO imagery I'm gonna show you here.

1:25

Now the, the Corona imagery, um,

1:30

it's the kind of stir imagery right here,

1:32

and we can see the right satic nerve right here

1:36

and the left satic nerve, high signal intensity

1:39

in this left, left satic nerve in comparison

1:42

with the right satic nerve.

1:44

And this is that T two space imagery that is, uh,

1:49

that we use a lot to evaluate

1:51

and to reconstruct some, some, um, uh,

1:56

some images doing neurography.

1:58

And we can see the difference between the left satic nerve

2:01

and the right satic nerve.

2:03

And in this case, just to, just to, to show, uh,

2:07

what happened, uh, with this case.

2:10

Uh, so this was the finding, uh, this was the finding

2:14

that I just showed you,

2:16

and this was our, uh, neurography showing the difference

2:20

between the two nerves, the high signal intensity

2:23

of the left sciatic nerve.

2:24

This is post contrast contrast imaging showing the,

2:28

the enhancement of the left, left side nerve.

2:31

The patient also has signals, uh, signs

2:34

of isco femoral impingement, at least for, uh, by image.

2:38

I'm not, uh, not clinically, I think.

2:41

And I I just wanna show the, the ERV vision area

2:46

that was happening at the posterior type of the patient

2:51

and also add the lag, uh, the, the left leg

2:54

of the patient when you compare

2:56

with the right leg of the patient. And

2:58

One year later, the patient come to us to do a follow up.

3:03

And in this follow up she was, uh, asymptomatic

3:07

and, uh, by imaging the nerve,

3:10

the left side nerve, it's okay.

3:13

There is no lesion. Uh, we can, we can't see any lesion, uh,

3:17

at, at the left sciatic nerve.

3:19

So it was a happy ending of this in this case.

3:23

And with that, with this happy ending, I finished my,

3:28

uh, participation, uh, as, uh, panelists showing cases

3:33

for this course.
