Here's a patient with a brainstem lesion in the right
0:03
lateral aspect of the brainstem.
0:05
It's a very hyperintensity
0:06
and T two clear defined margin here.
0:11
Here's the appearance on T, one way of imaging,
0:13
and there's some heterogeneous central enhancement on, um,
0:17
post contrast T one.
0:19
The FST imaging shows sort of like an exophytic component
0:23
extending into the porous acoustics.
0:26
Um, the direct link coded fractional antrop maps showed the
0:29
descending fibers of the corticospinal tract were actually
0:32
pushed over and not infiltrated.
0:36
So this patient underwent resection.
0:38
It did a subtotal resection. Here's the intraoperative MRI.
0:43
They went back and did more
0:44
and got a near total to gross total resection of the lesion.
0:49
So you can see the preoperative image,
0:50
the first intraoperative MRI,
0:52
the second intraoperative, MRI.
0:54
They had a transient left-sided motor weakness,
0:56
but no permanent weakness and motor improved from baseline.
0:59
This was called the DIPG at other hospitals,
1:01
but the final diagnosis was a pilocytic astrocytoma.
1:04
So we felt comfortable based upon the other imaging features
1:08
that this was amenable to resection.
1:09
But this is another reason why, um, you know,
1:13
biopsying a lesion that may not be classic
1:15
or typical can really help guide you in the right direction.
