Hello, everyone.
0:02
Dr. Sidney Levy here, continuing our discussion
0:02
4 00:00:04,760 --> 00:00:08,320 of the diagnosis and staging of base of
0:08
tongue oropharyngeal squamous cell malignancy.
0:11
I would like to formally stage this
0:13
example case for you in this vignette.
0:17
I have post-contrast T1 weighted imaging
0:20
in three planes with fat suppression.
0:23
And we are looking at a bilateral base of
0:27
tongue malignancy which has originated on the
0:30
right-hand side but since spread to the left.
0:33
The first thing I'd like to do is to draw the
0:35
outline of the tumor for you to help orient you.
0:38
So it is the region of abnormal enhancement
0:42
which is clearly visible in all three planes.
0:47
So what are the salient features to T stage this tumor?
0:51
The first one
0:53
is how much does it measure in its maximal dimension.
0:57
So, this tumor, if we measure it from here to here,
1:02
is about four centimeters in maximal dimension.
1:06
If we're in any doubt, you should always give the
1:08
benefit of the doubt to the lower measurement.
1:11
But in this case, we can confidently
1:13
say that this tumor is just over four
1:16
centimeters in maximal dimension.
1:18
So that automatically places
1:20
it into at least T3 category.
1:24
It also has crossed over to the contralateral side.
1:28
The other important features are
1:30
invasion of nearby structures.
1:33
So these include, as previously discussed in
1:36
another vignette, extrinsic tongue musculature.
1:40
This tumor is involving the genioglossus.
1:45
So they are the most commonly
1:47
involved extrinsic tongue muscles.
1:50
I will draw them for you.
1:54
This is the right one.
1:55
And then the left one, as you can see, has
1:57
been partially obscured at this level by
2:01
the tumor which has extended posteriorly.
2:04
We can also get an impression of it
2:06
in this region here on the sagittal.
2:08
So, given that this tumor has invaded extrinsic
2:12
tongue musculature, it is automatically upgraded
2:15
to a T4A tumor, irrespective of its dimensions.
2:20
It is not a T4B tumor because the masticator
2:23
space, the nasopharynx, the skull base,
2:27
and the carotid artery are not involved.
2:29
In our next vignette, we will end stage this tumor.
