Here is an example of an IDH mutated glioma
0:05
in a patient, 28-year-old male,
0:08
presenting with headaches and otherwise clinically intact.
0:12
You can see that MRI shows a very large
0:17
tumor involving the frontal lobe.
0:19
It's actually extending across the midline by the volatile
0:23
frontal lobe involvement,
0:25
with hardly any edema
0:27
around this very well-defined mass,
0:30
which shows some heterogenous fatty enhancement
0:33
within the tumor, and more importantly,
0:36
if you look at the CT scan done a day earlier,
0:40
it actually shows you that this tumor
0:42
has some areas of calcification,
0:45
which in fact could also be confirmed on
0:49
the susceptibility weighted imaging.
0:52
All our brain tumor patients
0:54
also undergo susceptibility weighted imaging sequences,
0:57
and you can see these tumors
1:00
are mutated gliomas.
1:03
They might show areas of hemorrhage
1:06
as this one is showing,
1:07
but also some of these susceptibility blooming signal,
1:12
which we are seeing,
1:13
is also related to calcification.
1:16
As you can see, some of these areas are dark on
1:19
phase imaging right over here,
1:21
which kind of corresponds to the calcification
1:24
we saw on the CT scan.
1:27
So, you know, these tumors,
1:29
they could be calcified,
1:30
and once we see the calcification in a tumor,
1:34
which looks like that, in the frontal lobe in a young patient,
1:38
you can suggest a diagnosis of an oligodendroglioma,
1:41
which this turned out.
