Hello, everyone.
0:02
3 00:00:02,130 --> 00:00:05,790 Dr. Sidney Levy here, continuing our discussion on the
0:05
diagnosis and staging of sinonasal squamous cell carcinoma.
0:12
In this vignette, I'd like to discuss patterns
0:14
of spread of sinonasal squamous cell carcinoma.
0:19
I have an example here of a nasal cavity squamous cell
0:23
carcinoma with post-contrast T1-weighted imaging with fat
0:28
suppression in axial, coronal, and sagittal projections.
0:32
These malignancies can spread in almost all directions.
0:37
I will start off with this particular one,
0:39
which arose in the right nasal cavity here.
0:44
And as you can see, it has spread superiorly
0:49
into the ethmoidal air cells on the right-hand
0:53
side, and then through the cribriform plate
0:59
here into the anterior cranial fossa.
1:04
So this is a superior pattern of spread.
1:08
If the malignancy had arisen in the maxillary sinus, then
1:13
it can spread superiorly into the orbit, either directly
1:18
through the bony orbital floor or more indirectly via
1:23
the pterygopalatine fossa and inferior orbital fissure.
1:27
An alternative pattern of spread is inferiorly, in
1:30
which case the structures which can become compromised
1:34
are the hard palate here, particularly if it's a nasal
1:39
cavity malignancy heading downwards, or alternatively,
1:44
the maxillary alveolar process, if the malignancy has
1:49
started in the maxillary sinus and then eroded the
1:54
floor of that into the maxillary alveolar process.
1:59
An alternative mode of spread is anteriorly, and
2:02
sometimes these malignancies will spread directly
2:05
into the soft tissues of the cheek or the nose.
2:10
Alternatively, it can spread posteriorly into the
2:14
retroantral fat pad, pterygopalatine fossa, or more
2:18
laterally into the masticator spaces, which are here.
2:25
One other mode of spread is perineural tumor spread,
2:30
where a malignancy spreads along the course
2:33
of major branches of the trigeminal nerve.
2:36
For sinonasal squamous cell malignancy, it may spread via
2:41
the maxillary, or V2 division of the trigeminal nerve,
2:48
and its major branches, including the infraorbital nerve.
2:52
This has not occurred in this particular case, but it
2:54
is always something that is worth watching out for.
