Well, thank you very much for sticking it out to the end.

0:04

I hope that this course was useful to you.

0:06

We initially went through several of the benign tumors

0:10

of the brain as well as the posterior fossa tumors,

0:13

and then we shifted to looking at gliomas.

0:17

The emphasis on the gliomas is the introduction

0:21

to the 2021 WHO classification

0:25

and the importance of that with regard to

0:28

how we describe tumors now,

0:30

with more emphasis on the molecular genetics

0:34

than the histopathologic features of the lesion,

0:37

there are some correlations between imaging findings

0:40

and those immunogenetics and molecular typings,

0:44

and we've emphasized those with regard to, for example,

0:47

the flare mismatch sign.

0:49

As a representative of IDH mutant,

0:52

we talked about the four types of medulloblastomas

0:56

and how they tend to look differently, similarly

0:59

with the appendamoma.

1:01

And we also introduce the concepts of the, um,

1:05

the midline gliomas

1:07

and the correlation with that,

1:09

with the H three K 27 M mutation.

1:13

So I hope that this, uh, has been helpful to you as a primer

1:17

for the neuroradiology of brain tumors, both benign

1:22

as well as the gliomas.

1:25

And, um, enjoy the rest of your day.
