Here is another MR scan of a
0:02
patient who is suspected of having
0:04
left parotid sialodocholithiasis.
0:09
We're going to start from below and scroll upward.
0:11
So here we are at the angle of the mandible,
0:14
the tail of the parotid gland.
0:15
We come upward and we see all this enlarged ductal
0:19
pattern that is not present on the contralateral side.
0:23
On the contralateral side,
0:25
we do see the prominence of the
0:29
venous system here and then the ductal system
0:32
coming towards the second mandibular,
0:35
second maxillary molar region. However,
0:37
within the left gland,
0:39
you see much larger ductal system,
0:42
more acinar pattern,
0:44
and you actually are able to see a calculus within
0:48
the proximal portion of Stensen's duct.
0:52
You may also wonder here about
0:57
whether or not there is some sludge.
1:00
Some sludge here.
1:02
Calcified sludge within the opening to the buccinator
1:07
muscle of Stensen's duct on the left side.
1:11
So this would be MR evidence of calculi in the ducts,
1:17
as well as probably a focal calcification
1:19
here within the gland seen here.
1:22
It doesn't look like a venous structure.
1:23
It looks like a calcification with
1:25
the ductal system being dilated.
1:28
This is kind of a chronic sialadenitis appearance to the
1:31
ductal system with areas of narrowing and
1:34
widening analogous to, for example,
1:37
fibromuscular dysplasia in the blood vessels.
