So, this is a very typical scenario
0:03
we see in clinical practice
0:05
where you have a patient,
0:08
74-year-old male, presenting with
0:12
cognitive decline going on for the last 2 months
0:15
and memory loss,
0:17
as well as some speech difficulties.
0:20
In MRI brain, as you can see,
0:23
we have different sequences,
0:25
FLAIR T2 post-contrast,
0:27
showing you a very ugly necrotic enhancing mass
0:33
with a lot of swelling and edema
0:37
in the right cerebral hemisphere
0:39
and also has some areas of
0:42
respective diffusion in the solid part.
0:45
And if I have to show you the perfusion maps,
0:48
it's very vascular.
0:49
You can see the blood volume is
0:52
markedly increased
0:53
in the solid enhancing part of the tumor,
0:57
even over here.
0:59
One of the things I struggle with is
1:01
trying to exactly localize where this
1:03
enhancing necrotic mass is,
1:05
just based on the axial images,
1:08
and that's where I would suggest
1:11
that everybody should look at the sagittal
1:13
reconstructed images,
1:16
and that's...
1:16
those are very helpful to decide.
1:18
For example,
1:20
based on this information I got from the sagittal images,
1:23
you can see that this tumor
1:25
is actually in the temporal lobe only.
1:28
It's not involving the frontal lobe,
1:31
probably going a little bit into the insula over here,
1:35
but definitely not involving the frontal lobe.
1:38
All the edema and swelling is in the temporal lobe.
1:41
And this is what we typically see with
1:44
primary de novo GBMs.
1:47
The reason I would like to call this a primary de novo GBM
1:51
IDH wild-type is because of the age,
1:54
more than 40 years.
1:56
This patient is 75
1:57
and presenting with subsequent neurological deficit.
2:01
Now, we also know that these tumors
2:04
are really bad tumors to have
2:06
and this is what happens.
2:08
This is a scan done a year and a half.
2:11
I'm not showing you all the follow-ups.
2:14
This patient did
2:15
undergo all the therapy regimens available,
2:18
including surgery, initial debulking
2:21
followed by a standard Stupp regimen,
2:24
and even a vast and therapy for the recurrent tumor.
2:28
But you can see
2:29
you know
2:30
the tumor is clearly increasing in size.
2:34
It is progressive
2:36
and this unfortunate patient ended up dying
2:39
after 20 months of the initial diagnosis.
