Parotid Lymphoma on PET-CT

HIDE
PrevNext

0:00

This is the PET scan on the woman that we just

0:05

demonstrated, had a relatively well-defined mass in the

0:11

right parotid gland.

0:12

As we scroll the images,

0:15

as you can see,

0:15

the normal lymphoid tissue of the nasopharynx adenoidal

0:20

tissue shows radiotracer uptake, which is okay.

0:24

However, here in the parotid gland, we have that big,

0:27

round mass that we saw on the CT scan,

0:31

and that represents a patient with a lymphoma,

0:35

which is showing high FDG avidity.

0:39

We want to look at the entire neck on this individual to

0:42

ensure that the patient does not have additional lymph

0:45

adenopathy. As we scroll further inferiorly,

0:50

you might identify that there

0:53

looks like there's a possible separate mass that is

0:58

superimposed on the mandibular

1:00

posterior portion of the mandibular angle here,

1:05

which could represent an intraparotid lymph node.

1:08

It certainly is either an exophytic portion

1:11

of the tumor or a separate lymph node.

1:13

This ended up being a separate lymph node.

1:17

The remainder of the evaluation of the

1:19

neck was negative.

1:21

So this high avidity,

1:23

very high uptake of the FDG PET

1:27

is typical of lymphoma,

1:29

and it did help identify additional lymph node in

1:33

the parotid gland.

1:35

On the contralateral side,

1:37

I'm not sure what this is.

1:38

This could be muscular.

1:41

muscular uptake in the styloglossus muscle.
