So for this very last scrollable case

0:02

that we'll be doing together, I've actually picked something

0:06

in the brain, which is very far away from the prostate.

0:08

So we are not even going to kind

0:10

of look at the prostate in this one.

0:11

There's some mild heterogeneous uptake.

0:13

Um, we'd be correlating with the MRI

0:14

and also why the patient presented, but I picked this case

0:17

because of an incidental finding.

0:20

So even on the rotating myth,

0:21

it's actually kind of tricky to see.

0:23

Let's kind of dial it up and see if we can find it,

0:25

but not so much.

0:27

But this is a good, um, reminder that we always have

0:30

to scroll through the entirety of our image stack regardless

0:34

of whether or not we're looking at the prostate or not.

0:36

Um, so the brain's still important.

0:38

This patient has had a craniotomy,

0:39

but if you come down here, you'll notice

0:41

that there's some abnormal uptake.

0:43

And this is right at the cerebellar pontine angle.

0:47

And there is PSMA expression in an intracranial lesion,

0:52

so cerebellum, and then we've got patchy increased uptake.

0:54

And this is another example of A-P-S-M-A expressing lesion

0:59

or a low grade neoplastic lesion

1:02

and sent it at the cerebellar pontine angle with,

1:04

unfortunately, I, the low dose CT doesn't show this as well

1:07

as the, the fusion 'cause of some beam hardening artifact,

1:10

but this was an example of a proven schwannoma.

1:13

So neurogenic tumors will demonstrate

1:15

some P sm a expression.

1:17

So it's important to kinda keep that in mind.

1:19

If you see an odd lesion, could this be a neurogenic tumor,

1:22

particularly in this location

1:23

or in the paraspinal regions with typical features?

1:26

Um, so not all that is psma AVID is prostate cancer.

1:30

And this is kind of similar in the vein to

1:31

what we're seeing with ganglia.

1:32

We see ganglia with uptake

1:34

and so this is a peripheral nerve sheath tumor.

1:37

Um, and a nice example, one of that.
