Sometimes there is overlap of the imaging features
0:04
of allergic fungal sinusitis and polyposis.
0:09
In this case, we have a patient
0:11
who has on T one weight imaging hyperintense secretions,
0:15
which correspond to darker signal.
0:17
On the T two weight scan, we have the opacification
0:22
of the nasal cavity even into the Aries
0:24
as we've seen previously.
0:26
So this patient does have polyps,
0:29
but also has features
0:30
of allergic fungal sinusitis right on T one dark on the T
0:35
two wade scan with expansion of the perinasal sinuses
0:39
and on post gadolinium hand scan this kind
0:43
of irregular enhancement that we might be associated
0:46
with the presence of polyps in this case.
0:50
You also see there are areas where the bone is so thin
0:54
that we lose the normal periosteum dark signal intensity
0:59
on the T one weighted
1:01
and post gadolinium T one weighted scan,
1:03
and even on the T two weighted scan.
1:05
So this is very thin bone, so this is polyposis,
1:09
but this is associated with the allergic fungal sinusitis
1:13
as well as the nasal polyps which are extending even
1:17
to the anterior Aries of the nasal cavity.
