I want to talk about some miscellaneous structures on the
0:03
midline sagittal MR that we frequently forget to look at.
0:07
The pituitary gland is one of them.
0:09
We've got the adenohypophysis or pars distalis
0:13
and pars intermedia right there.
0:15
The pars nervosa with a little bit of fat in the back,
0:17
the pituitary stalk or pituitary infundibulum,
0:23
and the median eminence,
0:24
as it comes up and fans out a little bit.
0:27
More importantly,
0:28
structures that we frequently forget to look at,
0:30
most of the time we don't forget to look at
0:32
the pituitary gland, includes the superior sagittal sinus,
0:36
which will frequently have in plain,
0:38
slightly hyperintense wispy flow.
0:41
But it shouldn't look like a big fat intermediate
0:44
signal intensity gray worm.
0:46
And I'm going to make it gray intentionally right now.
0:48
You'll see how hard it is to see,
0:50
because when it's gray and smooth
0:53
and you've lost any flow phenomenon,
0:56
it's going to blend with the adjacent gray brain,
0:59
and you're going to completely miss it.
1:01
So be on the lookout for an expansile solid,
1:06
non-flow phenomenon area of gray signal
1:09
throughout the superior sagittal sinus.
1:11
This is absolutely critical not to miss.
1:14
Anteriorly, you've got flow voids
1:15
and implant flow phenomena in the
1:17
basilar artery and in the basal plexus
1:20
of vessels and/or veins.
1:22
You've also got, anteriorly, the nasal cavity,
1:26
the sphenoid sinus,
1:27
and frontal sinus discussed previously.
1:30
One structure that is frequently overlooked,
1:32
especially in an adult, 50-year-old or 45-year-old,
1:36
is the adenoidal pad.
1:38
The adenoidal pad should be virtually nonexistent or flat.
1:41
So when it's hypertrophy,
1:43
you've got to consider things like Lymphoid hyperplasia,
1:45
and even in certain circumstances, if asymmetric,
1:48
nasopharyngeal carcinoma.
1:50
Don't forget to look at the uvula,
1:52
the opening of the oral pharynx, the base of the tongue.
1:56
That's it from me.
1:58
Pomeranz out.
1:59
That concludes miscellaneous structures,
2:01
you should take a look at on your sagittal midline scout.
