3 m.0:01
This was a patient who had metastatic neuroblastoma
0:05
with skull-based metastases.
0:08
We're starting in this neck
0:09
CT scan at the skull base.
0:12
So you can see the involvement of the craniofacial
0:14
region for which the patient had surgery.
0:17
You can see that the ethmoid sinus has been
0:19
operated on as well and the diffuse surgery
0:23
of the nasal septum, etc.
0:26
However, the patient appeared to have metastatic disease in
0:29
the retropharyngeal and carotid space region on the
0:33
right side. So let's look on the left side,
0:36
the internal carotid artery and the jugular vein,
0:39
in the poststyloid parapharyngeal space,
0:41
the carotid space. However,
0:43
on the right side we have this enhancing tissue
0:49
which is encasing the internal carotid artery.
0:54
So if we look for our internal carotid
0:58
artery at the carotid bifurcation,
1:01
we can see that there is diffuse involvement of the
1:07
internal carotid artery on the right side with
1:12
encasement by tumor that is enhancing.
1:16
And in fact,
1:17
we don't see the lumen of the internal carotid
1:20
artery as it is encased by the tumor.
1:23
If we continue up superiorly,
1:25
we can see that the carotid artery does reconstitute
1:28
at the petrous internal carotid artery.
1:30
So let's follow again the distal cervical internal
1:34
carotid artery here being encased
1:37
by this enhancing tumor.
1:40
So the 360 degrees of involvement of this carotid
1:44
artery by metastatic neuroblastoma suggests that indeed
1:48
this is encased and not surgically resectable.
1:53
And this is one of the examples of nodal metastases
1:58
that can lead to carotid encasement.
2:01
So you may have primary tumors of the systems
2:05
such as the hypopharynx or esophagus that was
2:08
described as well as lymph node metastases which
2:13
cause encasement and non-salvageable internal
2:17
carotid artery in this case.
