Hello everyone.
0:02
Dr. Sidney Levy here continuing our discussion
0:04
of laryngeal squamous cell malignancy.
0:08
We were talking about supraglottic tumors and I would
0:11
like to round that off by mentioning some of the
0:14
differential diagnoses of lesions in this region.
0:19
Firstly, one of the challenges that
0:22
head and neck radiologists often face
0:24
is deciding whether a tumor originates
0:29
or the piriform sinus, or the post cricoid space.
0:33
And that can be difficult, especially when
0:36
normal anatomical structures have been effaced.
0:39
But as a general rule, it's worth remembering
0:42
that, firstly, regarding the areoepiglottic
0:45
folds, which we have here, although they're
0:49
quite abnormal, a supraglottic tumor will
0:52
tend to be centered medial
0:55
to the center of the areoepiglottic
0:57
fold, whereas a piriform sinus tumor
1:00
will tend to be centered laterally.
1:02
And it's just worth remembering that the lateral
1:04
wall of the areoepiglottic fold is considered part
1:08
of the piriform sinus, whereas the medial wall
1:11
is considered part of the supraglottic larynx.
1:14
So, you just need to make a judgment as
1:16
to where you think the tumor is centered.
1:18
Post cricoid space tumors tend to be a little bit
1:22
further down and a little bit more medial as well.
1:27
They're often midline tumors, most of the time.
1:30
Other differentials in this region might
1:32
include adenoid cystic carcinoma or
1:35
other minor salivary gland malignancy.
1:38
But this is usually a diagnosis made
1:40
retrospectively with the help of a pathologist.
1:44
And occasionally, you may see autoimmune conditions
1:48
such as rheumatoid arthritis or sarcoidosis which
1:51
can mimic a tumor in the supraglottic region.
1:55
Rarely, you may see the sequelae or consequences
2:00
of gastroesophageal reflux disease in this area.
2:05
A laryngocele is usually readily
2:07
distinguishable by being either a fluid or
2:10
air filled cystic structure in the area.
2:13
But remember, a laryngocele
2:15
can also occur with a tumor.
2:17
So, just because you see a structure that looks like
2:20
a laryngocele, you need to look very carefully to
2:23
make sure that there isn't an associated mass lesion.
