This was a seven-month-old child who had spasticity

0:04

in the lower extremities, bilaterally.

0:06

We have the T1-weighted scan,

0:08

the STIR image and an axial T1-weighted scan.

0:12

As we look at the T1-weighted scan,

0:14

we see that we have a lesion that

0:16

is brightened signal intensity,

0:17

which is posterior to the spinal cord.

0:20

In what compartment is it located?

0:22

Well, we see that the CSF space is widened at the border

0:26

of the lesion and the spinal cord

0:28

is separate from the lesion.

0:29

And therefore we are in the intradural

0:32

extramedullary space.

0:34

The spinal cord is actually terminating

0:35

at an appropriate level,

0:37

so there is no tethering of the spinal cord.

0:40

And yet this lesion,

0:41

which is bright on T1 and suppresses on the

0:44

STIR image, is clearly containing fat,

0:46

and that's verified also on T1-weighted scan

0:50

without contrast, showing bright signal intensity.

0:52

On this scan, the spinal cord is being displaced anteriorly.

0:56

So this is an example of a lipoma in the

1:00

intradural extramedullary space without

1:03

associated spinal dysraphism.
