Okay,
0:01
so let's take a look at this first pathologic case.
0:04
And what we notice almost immediately
0:07
is that there is opacification,
0:09
which is present in the middle ear cavity bilaterally.
0:13
So, let's stop at this level.
0:14
So at this level,
0:16
we see, on the right side, the head of the malleus
0:18
and the short process of the incus,
0:21
the ice cream and the ice cream cone.
0:23
And there is opacification in the middle ear cavity,
0:26
as well as in the anterior epitympanic space.
0:30
And we also see the opacification of the mastoid
0:33
air cells with the aditus ad antrum,
0:35
the connection between the middle ear
0:37
cavity and the mastoid antrum.
0:39
And we don't really see destruction of these mastoid septae.
0:45
Might be a little bit concerned down here,
0:47
but it looks almost symmetrical.
0:49
That might just be normal variation.
0:51
And you see that there is soft tissue which is all
0:56
around the neck of the malleus and the long process of
1:00
the incus extending to the stapes.
1:02
And even at the oval window, there is soft tissue there.
1:05
And this is also seen on the left side.
1:09
So on the left side, not as bad.
1:11
We see mastoid fluid.
1:13
We do see some soft tissue around the incudostapedial
1:17
joint and the stapes.
1:19
And I'm saying soft tissue,
1:21
but this is usually just fluid.
1:24
And in this situation,
1:26
we would comment about the otomastoiditis without any
1:31
complications identified that would suggest
1:33
either coalescent mastoiditis or mass effect
1:36
that might suggest a cholesteatoma.
1:39
Now, as I mentioned, we want to look at the scout view.
1:43
And why do we want to look at the scout view?
1:45
So the scout view, in this case, is to identify that this
1:49
is an adult. So once we have an adult with otomastoiditis,
1:53
we want to make sure that we're going to be looking
1:55
at the nasopharynx. And once again, this patient,
2:00
for what looked like an older person on the scout image,
2:06
has an awful lot of nasopharyngeal adenoidal tissue,
2:10
and it's somewhat asymmetrical to the left side.
2:14
So this is the case that although we would have a good
2:17
description of the middle ear cavity and mastoid issues,
2:22
we would also talk about the prominence of the adenoidal
2:26
tissue greater than expected for a 60-year-old,
2:28
with some asymmetry to the left side.
2:31
Recommend endoscopic evaluation.
2:34
And this may be a patient who,
2:36
in this case, was an HIV patient
2:39
who had adenoidal hypertrophy,
2:41
which may have occluded the eustachian tube orifices
2:44
bilaterally and led to eustachian tube dysfunction
2:48
and bilateral otomastoiditis.
