0:00

Moving on, um, a along that kind of same kind of family

0:05

of, uh, masses.

0:07

Just wanted to show this case here.

0:09

What we're seeing on this T two sequence is a

0:14

kind of nodular, large rounded mass,

0:17

and a first glance kind of very confusing.

0:20

Like, what is this? Where is it coming from?

0:22

Um, again, very dark signal on T two.

0:27

There's not that many things that have such dark signals.

0:31

So we talked about, uh, fibromatosis.

0:34

Um, you can have desmoid tumors,

0:37

which is aggressive fibromatosis,

0:39

but you also want to keep in mind, uh, this entity, um,

0:42

which is another thing that can have dark signal.

0:44

And part of the reason it has dark signal is, uh, due

0:48

to the hemosiderin,

0:49

the old blood products within this lesion, we're used

0:53

to seeing this lesion within a joint.

0:56

Um, and it can be a diffuse or focal form,

0:59

but it actually can also be a long tendon sheaths as well.

1:03

Uh, and so, um, you guys probably already know I'm going

1:06

to be talking about, uh, pigmented vi nodular synovitis.

1:10

Um, the newer kind

1:12

of term is tenino synovial giant cell tumor.

1:16

Um, and so, sorry, this is having trouble loading,

1:19

but basically it was a very hypo intense,

1:22

um, mass like structure.

1:24

Um, and this was PVNS of the, uh,

1:29

of the hindfoot there.
