This was a patient who had discomfort in the left side

0:03

of the floor of the mouth and was being evaluated

0:06

for a potential cyst in the floor of the mouth.

0:10

When we did the MRI scan,

0:11

we were a little bit confused because we saw this big

0:13

black thing that was associated with

0:16

the submandibular gland.

0:17

Now, this is a big black thing in the gland

0:20

rather than the duct.

0:21

If we look at the T2-weighted scan,

0:25

we see that it is entirely within the gland.

0:28

But within the gland,

0:30

you see focal ductal dilatation of the

0:33

glandular ductal system.

0:34

So this was not a Wharton's duct,

0:37

a submandibular ductal calcification.

0:39

This was a glandular calcification that

0:41

was obstructing the ductal system,

0:43

compared these ducts to the normal caliber

0:46

of the right-sided duct.

0:48

Not only that, but on the right side,

0:50

you see a nice example of Wharton's duct

0:53

crossing into the sublingual space.

0:55

Here we have the mass that is still

0:58

contained within the submandibular tissue.

1:01

On post-gadolinium-enhanced scan, we notice

1:04

that there is this non-enhancing

1:06

lesion within the gland.

1:08

The gland itself is a little bit enlarged

1:10

compared to the right side.

1:12

Nothing going on in the floor of the mouth.

1:14

This was a big rock.

1:16

This was a big stone in the gland.

1:18

And there is a difference between the stones in

1:21

the gland versus the stones in the ducts.

1:23

The stones in the ducts tend to be obstructive and lead

1:26

to more symptoms than those that are

1:28

just located in the gland itself.

1:31

And.
