Case: NSIP in Systemic Sclerosis (SSc)

HIDE
PrevNext

0:00

So here's a patient with NSIP.

0:04

It's relatively based

0:06

or predominant, actually, I think pretty convincingly.

0:09

So there are areas of reticulation

0:11

and traction bronchiectasis.

0:12

If all you saw was this in the cost frank angle,

0:15

this is the only slice that you had.

0:17

I think that most people, including myself would say, oh,

0:20

this actually feels like maybe probable UIP.

0:22

Maybe this is early UIP.

0:25

I'm not sure if there's honeycombing down here,

0:27

but if you look at the rest of the lung parenchyma

0:29

and in particular right around here

0:32

and look at the distribution in the axial plane, you'll see

0:35

that there's clearly relative subpleural sparing

0:38

and so are predominant relative subpleural sparing

0:43

reticular abnormality, traction bronchis.

0:45

This is a case of fibrotic hp,

0:47

and this patient has systemic sclerosis.

0:50

Remember what I told you before, patients

0:51

with NSIP almost always their diseases related to

0:55

a secondary cause,

0:56

and in this case it's related to systemic sclerosis.

1:01

You'd like to see a little bit of a dilate esophagus

1:03

to make it classic, but sometimes they just don't have it.

1:04

They don't have the dilate esophagus,

1:06

even if they have the underlying disease.
