As opposed to degenerative spondylomyelopathy,
0:04
most of the other lesions of the spinal cord that
0:07
we will examine will lead to cord expansion with
0:11
a possible exception of demyelinating diseases.
0:15
With demyelinating diseases,
0:16
you may see cord atrophy in those patients who
0:19
have undergone transverse myelitis and we
0:22
are seeing it in the chronic phase.
0:24
So what we're to do is to start
0:26
in on the neoplastic category.
0:28
And within the neoplastic category, you see that
0:30
the most common of these lesions are going
0:33
to be astrocytoma, ependymoma,
0:36
metastases and hemangioblastoma.
0:39
There are other unusual neoplasms that can affect
0:42
the spinal cord that we will also see in our
0:45
cases. So let's start in on the neoplastic cases.
