This is a case of a 57-year-old female

0:03

that we have seen previously.

0:07

But in this case I'm going to focus on the findings

0:11

related to the primary lesion.

0:15

She presented with abdominal pain due to polyhis

0:20

and was found incidentally a gastric mass

0:24

and the biopsy revealed well differentiated

0:29

neuroendocrine tumor.

0:31

So this study was done for staging.

0:34

When we start looking at this case, I'm going

0:37

to change the window to be able to identify the areas

0:41

of abnormality given that as default as you can see,

0:46

the liver has very intense uptake and so does the spleen.

0:50

So in order to separate these structures, I'm going

0:53

to manually change that contrast.

0:56

So now that I have done that, I'm looking at the me images

1:00

and I identify that there's an abnormal intense

1:05

focal uptake in the region of the upper abdomen,

1:10

and the rest seems overall, uh, physiologic,

1:13

but we will look at it in better in detail.

1:19

So centering ourselves in the abdomen

1:23

and scrolling through, we can see that there is these area

1:27

of uptake correlating to a partially calcified mass that

1:32

arises from the cardio of the stomach.

1:36

And this was consistent

1:37

with a biopsy proven neuroendocrine tumor.

1:41

Now, the key of these study not to identify the primary,

1:45

which they knew, but

1:47

to address if there is distant disease or novel disease.

1:51

In this case, we did not identify any other areas of noal

1:56

or disease, so this case was localized to the stomach.

2:02

One thing to notice is that there is a focus

2:04

of uptake lower down in the left hemi abdomen, that if you

2:10

look at it as rounds of tissue,

2:14

which is uh, spleen, the same way

2:17

that the spleen has uptake the spleen or accessory.

2:21

Spleens also take up tracer.
