Complex Ovarian “Masses” – Overview

0:01

All right, so now we'll change

0:02

gears a little bit and we'll talk

0:03

about more complex ovarian masses.

0:07

And you'll notice here that I have mass

0:09

again in quote because we use that

0:11

term for a wide variety of different

0:14

pathologies, but let's just zoom out a

0:17

little bit and talk about what a mass is.

0:19

It's actually a space-occupying

0:21

region with its own volume.

0:24

So, I always tell my residents and

0:26

fellows to be very careful using the word

0:28

mass because even though that's technically

0:31

correct, it's really just a lesion that

0:33

occupies space, it has a negative connotation.

0:37

When people read the word mass in their

0:38

report, they automatically think cancer.

0:41

So we need to remember that masses can be

0:43

neoplastic or non-neoplastic, and that can

0:46

range from a benign tumor to a malignant tumor.

0:49

A mass can also be due to

0:51

hemorrhage or an endometrioma.

0:53

It can be due to a cyst.

0:55

It could be due to post-surgical or inflammatory

0:58

conditions caused by adhesions as well.

1:02

So, wide spectrum of abnormalities

1:04

that can cause masses.

1:06

And we'll just take it slow.

1:07

We'll start from benign and move our way over

1:09

to the more sinister and malignant lesions.

1:12

So in terms of MRI, there are certain ovarian

1:15

masses which do have unique MRI features.

1:18

So those include mature and immature teratomas,

1:22

endometriomas, which we talked about,

1:24

and then fibrous lesions, which have low T2

1:27

signal, including fibroma, fibrothecoma,

1:30

cystadenofibroma, and Brenner tumor.

1:33

So we'll talk about, in general,

1:35

we'll go over these categories of

1:38

lesions and their MRI features.
