So this is a different patient who has the same diagnosis.
0:04
In this case, finally, we get a lesion on the left side.
0:07
So on the post-gadolinium enhanced scan of this patient,
0:10
who presented with pulsatile tinnitus,
0:13
we see contrast enhancement in the expected location
0:17
of the geniculate ganglion of the facial nerve,
0:21
and there's a little bit more extra enhancement of the
0:24
region of the bone which houses the geniculate ganglion.
0:29
And although this is relatively small in size,
0:33
you notice that it's definitely asymmetrical
0:35
with the contralateral side.
0:37
And this represents a post-gadolinium enhanced
0:40
MR appearance of the facial hemangioma.
0:44
Again, facial hemangioma should be referred to really as a
0:48
venous vascular malformation of the
0:51
facial nerve and the bone around it.
0:53
So it actually, usually resides within the bone.
0:57
On the CISS image, not much can be seen here.
1:01
Just this little extra soft tissue at the geniculate
1:04
ganglion on the left side compared with the right side,
1:09
representing the soft tissue mass of a venous
1:12
vascular malformation of the facial nerve,
1:14
so-called facial nerve hemangioma.
