This is our third example of ependymoma.
0:04
This is what is known as a myxopapillary ependymoma.
0:08
The difference between the myxopapillary ependymoma
0:11
and the other cord ependymomas
0:13
is its predilection for the filum.
0:16
The myxopapillary ependymoma is considered an
0:20
intradural extramedullary lesion, even though
0:25
it is involving the filum,
0:28
which is the extension of the spinal cord.
0:30
So the spinal cord, as you can see,
0:32
is ending at the appropriate L1 level,
0:36
and we see this lesion which expands from that
0:40
termination, which is the filum.
0:42
So this is a myxopapillary ependymoma.
0:45
It's an ependymoma that typically occurs in an
0:47
older age group than the more stereotypical cord
0:52
ependymomas, and it may be associated with calcification,
0:55
as well as hemorrhage,
0:57
but it occurs in the lumbosacral region.
1:02
The myxopapillary ependymoma has variable
1:06
contrast enhancement and is usually,
1:09
as one would expect, affecting the lower
1:12
extremities, as well as bowel and bladder continents.
