This 56-year-old patient fell and had a shoulder
0:03
dislocation and, by the way, has axillary nerve dysfunction.
0:08
But I'd like to highlight and focus on these masses
0:11
in front of the shoulder in the axial projection.
0:16
They're very glom-like, or glenolabral
0:19
ovoid mass-like, or they look like masses.
0:22
So what are they?
0:24
Well, first of all, look in the bicipital groove.
0:27
It's empty.
0:28
The transverse ligament, predominantly made up
0:30
of the coracohumeral ligament is ruptured.
0:32
And what is this rounded oval mass?
0:36
It's the dislocated tendinotic
0:38
hypertrophied biceps long head.
0:41
We've got another mass.
0:42
Look at this gigantic mass right here.
0:46
It consists of inflammatory tissue and synovial hypertrophy.
0:50
Now, if this was a piece of labrum, triangulated
0:52
labrum inside it, that had torn off inferiorly and
0:58
migrated superiorly, we'd call it a glom lesion.
1:01
A glenolabral ovoid mass.
1:03
Without it, we call it a pseudoglom lesion, or
1:06
a tumor-factive area of synovial hypertrophy.
1:10
As we go down, we do see the inferior labrum
1:14
intact, but when we get to the axillary region,
1:17
the axillary portion of the labrum is injured.
1:19
So it isn't quite clear, clinically,
1:22
whether that's a piece of labrum or not.
1:24
If it's a labrum, then it's a glom lesion.
1:27
If it's not a labrum, it's a pseudoglom lesion.
1:30
And here's another fake glom lesion
1:32
from the dislocated biceps long head.
1:36
And that concludes our discussion of gloms and pseudogloms.
1:40
See our other vignette on the diagnostic glom lesion.
