Hello everyone, Sidney Levy here discussing
0:04
laryngeal squamous cell malignancy.
0:07
We've discussed supraglottic and glottic tumors, and
0:11
we've used an example of a large transglottic tumor.
0:14
I'd like to round off our discussion
0:16
by mentioning the subglottis.
0:18
Subglottic tumors carry imaging features
0:22
of being either infiltrative or exophytic.
0:25
and tend to narrow the subglottis,
0:27
which is usually a smooth, round contour.
0:30
So, one of the first indicators of a subglottic
0:34
tumor is an irregularity to the normal
0:38
ovoid or round contour of the subglottis.
0:41
So, as you can see here, this is abnormal.
0:45
We are well and truly into the subglottis
0:48
by this stage, and we should have a
0:51
nice rounded contour, smooth contour.
0:54
There shouldn't be any bulges or
0:56
projections like there is here.
0:58
The tumors themselves are similar
1:00
to other laryngeal tumors.
1:02
T1 hypointense to intermediate, T2 intermediate
1:05
signal enhancement, which may be variable,
1:09
maybe homogeneous or heterogeneous.
1:12
You need to make a comment on the status of the cartilages,
1:15
and the cartilage which is most at
1:17
threat at the level of the subglottis is the
1:20
cricoid cartilage, which is demonstrated here.
1:25
In this case, the tumor is not clearly
1:28
involving the cricoid cartilage.
1:32
CT is important for assisting in the assessment
1:35
of cartilage erosion or involvement and
1:39
should be obtained in quiet respiration.
1:41
It is important not to ascribe cartilage
1:44
involvement when sclerosis only is present.
1:48
So what I mean by that is if there is
1:51
sclerosis of cartilage, but there is no destruction,
1:56
you shouldn't say that the cartilage
1:58
is, is, is clearly involved.
2:01
With regards to subglottic tumors, nodal spread
2:04
is uncommon in a similar fashion to glottic tumors
2:07
because there is a paucity of lymphatic supply.
2:11
If there is locally advanced disease,
2:14
you may see involvement of regional
2:17
lymph nodes in the superior mediastinum.
2:20
So level 7 paratracheal lymph nodes are quite
2:24
commonly involved by subglottic tumors if
2:29
there has been locally advanced disease.
2:32
Afterwards, you may look at levels 3 and 4 as well.
2:36
Subglottic tumors tend to present late
2:39
and are often associated with cartilage
2:42
invasion and extralaryngeal extension.
2:46
So if you see tissue which is internal to the cricoid
2:50
ring, you should consider subglottic tumor and it may
2:55
require direct inspection by an otorhinolaryngologist.
