All right, so briefly we want to talk about
0:03
the MSK changes that we can see on MRI.
0:05
And this is not an MR enterography, although you
0:08
do need to keep your eyes out for these findings
0:13
manifestations of Crohn's and ulcerative colitis.
0:16
But this patient has bilateral changes adjacent
0:19
to their sacroiliac joints with a very dark
0:21
T2 appearance with relatively symmetric look.
0:25
I'm sorry, this is T1, and it's dark
0:27
on this T1 sequence in that region.
0:29
And then on the T2 weighted sequences,
0:32
it's also going to be very dark in that region.
0:35
And that corresponds to the
0:36
sclerosis that we typically see.
0:38
with sacroiliitis, and it is widely
0:42
apparent here on the CT scan.
0:44
So remember to look for that,
0:46
it's often symmetric.
0:47
It can involve the regions around the SI joints,
0:51
as well as you can see similar changes with a symmetric
0:54
appearance involving the spine with related sclerosis.
0:57
And another extraintestinal manifestation we need
1:01
to look for in the MSK system is avascular necrosis,
1:04
which can be related to the steroids and other
1:08
anti-inflammatories that these patients receive.
