So let's deal with each category one by one.

0:04

This is a serous tumor.

0:07

They are situated outside the duct, extraductal,

0:10

granular tumors, showing classical honeycomb

0:13

appearance because there are multiple cysts.

0:15

Those are measuring less than 2 centimeters.

0:18

Number of cysts are usually

0:19

more than six in number.

0:21

And they're usually situated in the

0:22

proximal pancreas and can demonstrate

0:24

central scarring or calcification.

0:29

So serous tumors are usually more than six cysts,

0:32

and less than 2 cm in size, and they demonstrate

0:34

thin septation, classical honeycombing appearance.

0:37

Mucinous tumors are less than six cysts,

0:40

more than 2 cm in size, and they

0:43

demonstrate thick and thin septations.

0:45

And serious tumor can be seen

0:46

with Von Hippel-Lindau Syndrome.

0:49

This is mucinous tumor in the

0:50

pancreatic tail, and we can see number

0:52

of cysts are less than 6 in number.

0:54

There are thick septations, and the

0:56

cysts are measuring more than 2 cm.

0:58

Mostly they are situated in the pancreatic

0:59

tail, and seen in middle-aged females.

1:03

These are SPN (Solid-pseudopapillary neoplasm) tumors.

1:05

And these are usually seen in

1:06

younger females, mostly in the tail,

1:08

but they can be situated anywhere.

1:10

But remember, SPN tumors are solid cystic.

1:12

They demonstrate hemorrhagic areas or

1:14

necrosis, but they can mimic sometimes

1:16

necrotic neuroendocrine tumor as well.

1:20

So we have to be very cautious

1:21

once we are calling it.

1:23

Once we see the patient age group, young female,

1:26

involving tail or distal pancreas, there is

1:29

hemorrhagic content on T1-weighted images,

1:31

then possibly we should lean towards this diagnosis.

1:33

If there is enhancement in the early

1:36

phase, specifically in the arterial phase,

1:39

and the parenchyma, which is not necrotic,

1:40

it is enhancing in the arterial phase,

1:42

that will lean towards neuroendocrine tumor.

1:45

And again, the age group will be

1:46

different, or it will be a male patient.
