Here is another example.
0:01
A 28-year-old male patient presenting with headaches,
0:06
had this large tumor, very well-defined, homogeneously
0:12
bright on T2-weighted images in the right frontal lobe,
0:16
shows dark signal on the FLAIR images.
0:19
Majority of the tumor,
0:21
the central part of the tumor, showing you dark signal,
0:23
loss of signal on the FLAIR images,
0:25
except this peripheral thin rim of bright signal
0:28
and again, not showing contrast enhancement,
0:32
as you can see on the post-contrast images.
0:34
And showing you a rather facilitated diffusion on
0:38
the diffusion-weighted images. And again,
0:41
this is another example of a classic T2
0:44
FLAIR mismatch sign,
0:46
as we now know is...
0:48
and proven to be an IDH-mutated,
0:51
non-correlated 1P/19Q co-relation was found,
0:56
and an IDH-mutated astrocytoma.
