Hello everyone.
0:03
Dr. Sydney Levy here.
0:05
Today, I'd like to formally stage this example
0:09
postcricoid region squamous cell carcinoma
0:12
as part of our hypopharyngeal series.
0:15
I have pre and post-contrast T1-weighted imaging in the
0:18
axial projection and pre-contrast T1-weighted imaging
0:22
in the sagittal projection on the right-hand side.
0:25
So firstly, to T staging, we need to measure the tumor.
0:30
This tumor extends from the postcricoid space
0:34
inferiorly into the upper cervical esophagus.
0:37
It measures approximately 4 centimeters,
0:42
so that would put it immediately into a category
0:46
of T2 or T3, depending on its exact dimension.
0:52
However, it has some adverse features, which
0:56
make it a moderately advanced malignancy.
1:00
Specifically, if we trace the tumor from up here,
1:05
we follow it down, there is actually direct tracheal
1:10
invasion at the level of the upper cervical esophagus.
1:16
That automatically confirms that the tumor
1:19
is involving esophageal muscle, which
1:22
upgrades it to a T4A tumor straight away.
1:26
But in addition to that, there is evidence of a
1:28
fistulous connection with the cervical trachea.
1:32
So that makes it a T4A tumor straight away.
1:36
Other features which are important to look for whether
1:41
there is laryngeal cartilage involvement, in particular,
1:45
the cricoid cartilage for postcricoid region masses.
1:50
This tumor has spared the posterior
1:52
wall of the cricoid cartilage here.
1:56
So that's not involved.
1:58
It is also not involving the hyoid bone, thyroid gland,
2:03
central compartment soft tissue, such as strap muscles.
2:07
And in addition, it is not involving the prevertebral fascia
2:11
or the carotid artery or other mediastinal structures.
2:15
All of the involvement is within the neck.
2:19
As we can see on the sagittal projection, we are
2:22
not seeing involvement of the superior mediastinum.
2:26
So therefore, this is a T4A tumor due to the
2:30
fact that it is involving esophageal muscle,
2:34
as it has extended inferiorly from the postcricoid
2:38
region into the upper cervical esophagus and then
2:42
invaded anteriorly into the cervical trachea.
2:47
In our next vignette, we will end stage this malignancy.
