This is a 25-year-old woman who has a history of trauma while
0:06
reaching overhead, and she's having pain with overhead motion.
0:11
So let's go over these images.
0:13
In these cases, we want to assess the superior labrum.
0:17
And we're going to start with the oblique coronal sequence.
0:20
In this case, it's an oblique coronal
0:23
fat-suppressed proton density.
0:25
And what I do is I try to find the supraglenoid tubercle.
0:30
So it's this projection of bone,
0:33
right on top of the glenoid rim where the biceps takes off.
0:38
And this is very important because the quality of the biceps is
0:41
going to determine the classification of superior labral tears.
0:46
So, in this case, we are seeing a fluid, linear collection that
0:53
is traversing the superior labrum at its base and extending
0:58
from the free margin into the base portion of the labrum.
1:05
When we go anterior to the long head of biceps tendon,
1:10
we can see that fluid collection, linear fluid collection
1:13
interposed between the free margin and the base of the labrum.
1:18
This has been called the audi cookie sign.
1:20
The cream is the fluid bright signal intensity,
1:25
and then the base and the free margin of the
1:27
labrum would be the dark portion of the cookie.
1:32
As we go posterior to the long head of biceps tendon,
1:36
we see that this tear is extending posterior to it.
1:39
So we have a SLAP type II that is extending through the base
1:44
of the labrum, and the long head of biceps tendon is intact.
1:48
There is no extension of the tear into the biceps.
1:51
So that is a key element in the classification.
1:55
It makes the difference between a type II and a type IV.
2:00
Now let's check the axial images.
2:02
So here we can better see the audi cookie sign.
2:06
So we have the fluid collection right there,
2:09
interposed between the free margin of the labrum
2:13
and the base of the labrum in this location.
2:17
We can also see the takeoff of the biceps.
2:20
And this is why the pathophysiology of superior
2:23
labral tears is usually related to traction
2:26
by the long head of biceps at its origin.
2:29
So we have that in this patient.
2:32
So, let's check the sagittal images in this patient, and
2:36
we can see right here the takeoff of the biceps tendon,
2:41
and we can track the biceps tendon on consecutive images.
2:45
We're going to do that right now, and we
2:48
can see the biceps is completely normal.
2:50
So, in summary, we have a superior labral tear extending
2:54
anterior and posterior to the long head of biceps origin
2:58
without extension into the biceps fibers themselves.
3:02
SLAP type II.

Report
Patient History
25-year-old female with left shoulder pain after injury while reaching above head.
Findings
ROTATOR CUFF: Supraspinatus, infraspinatus, teres minor, subscapularis and biceps as well as its labral anchor complex are intact.
SUBACROMIAL/SUBDELTOID BURSA: Normal.
MUSCLES (ROTATOR CUFF/DELTOID, TRAPEZIUS, PECTORALIS): Normal.
BICEPS TENDON: Normal.
AC JOINT: Mildly inflamed.
CORACOCLAVICULAR LIGAMENTS: Normal.
SUBACROMIAL ARCH/OUTLET: Normal.
SUBCORACOID ARCH: Normal.
GLENOHUMERAL JOINT: Normal.
GLENOID LABRUM: Abnormal. Extending from anterior to posterior is linear signal intensity that propagates into the posterior quadrant of the shoulder where none should be. On some coronal slices, the labral penetration is full depth, but on the majority, it is partial depth. Linear shape and location compatible with SLAP 2C. Some anterosuperior extension is highlighted.
BONES: Normal.
SUBCUTANEOUS SOFT TISSUES: Normal.
AXILLA: Normal.
Impressions
SLAP 2C with anterosuperior extension.
