Hello everyone.
0:02
Dr. Sidney Levy here, I'm continuing our
0:05
discussion of the diagnosis and staging of
0:07
oropharyngeal squamous cell malignancy, and
0:10
would now like to focus on the soft palate.
0:15
So soft palate tumors tend to be less common
0:17
than palatine tonsillar tumors, and can often be
0:22
difficult to appreciate in the axial plane, so it's
0:24
important to make use of orthogonal projections.
0:28
In this particular case, our sample tumor
0:31
is best appreciated in the coronal plane.
0:35
It's important to look for asymmetry of
0:38
the soft palate, because these tumors tend
0:41
to be infiltrative, sometimes ulcerated.
0:46
And sometimes the only clue you will get
0:48
is a diffuse asymmetric thickening or mass
0:51
like appearance of one of the soft palates.
0:55
So I'd like to, uh, use this case example where I
0:58
have pre-contrast T1-weighted imaging without fat
1:01
suppression, pre-contrast T2-weighted imaging with
1:04
fat suppression, and post-contrast T1-weighted imaging
1:08
with fat suppression on the right in the coronal plane.
1:13
I will draw the tumor for you.
1:15
The coronal plane demonstrates it most easily.
1:19
It is an asymmetric mass-like
1:21
thickening of the left soft palate.
1:25
It is easy to mistake these tumors
1:27
for palatine tonsillar tumors, and
1:30
a helpful landmark can be the uvula.
1:32
On T1-weighted imaging, they are often
1:37
iso-intense to adjacent
1:40
muscle, sometimes hypointense, or slightly
1:45
hypointense to normal soft palate mucosa.
1:50
In this case, not so.
1:52
On T2-weighted imaging, they are hyperintense
1:56
tumors, and you can always compare that with normal
1:59
soft palate, which will be less hyperintense.
2:03
So in this case, this is a normal soft palate.
2:07
This is the tumor, and you can see that the T2
2:10
signal intensity is increased on the left-hand side.
2:14
On post-contrast imaging, they usually demonstrate
2:17
either focal or diffuse moderate enhancement.
2:20
In this case, it is reasonably focal.
2:23
In our next vignette, we will discuss the
2:25
patterns of spread of these tumors, and then
2:28
go on to discuss patterns of nodal drainage.
