Let's look at a classification system for
0:04
benign prostatic hypertrophy on MR imaging.
0:08
We've got three two-dimensional fast
0:11
spin echo images of the prostate,
0:14
axial, sagittal, and coronal.
0:17
So let's begin with the low bar
0:20
classification system for BPH.
0:23
Type 1.
0:26
The enlargement is predominantly anterior
0:29
and pushes the urethra towards the back.
0:32
There is some anterior hypertrophy in this case.
0:37
Type 2.
0:39
There'd be a solitary area of retrourethral,
0:43
there's the urethra, retrourethral
0:45
enlargement, but above the verumontanum.
0:48
And we do have that.
0:51
If we had that and it was
0:52
isolated, it would be a type 2.
0:55
What's a type 3?
0:57
Type 3 is when you have both and they're balanced.
0:59
This one is a type 3.
1:01
It's balanced.
1:02
Both the anterior gland, maybe a little
1:05
imbalanced, and the posterosuperior gland
1:08
are enlarged above the verumontanum.
1:10
So I would say this one's a little
1:12
bigger, it's slightly imbalanced
1:14
towards the back than the front.
1:17
What's it type for?
1:19
Prominence of the median lobe, the periurethral
1:21
tissues, which may push the central zone up,
1:26
but also invaginate and encroach on the urethra.
1:30
As a pedunculated mass.
1:32
This one is actually the least common
1:34
and hardest to see because everything
1:37
gets crowded around the urethra.
1:39
And it's hard to know whether you're
1:40
seeing an intramural lesion that's
1:43
pushing in or a pedunculated lesion
1:46
with a stalk that's pushing in.
1:48
So that one to designate in an isolated
1:50
fashion as a type 4 requires very high
1:53
resolution one-millimeter or thinner MRI.
1:57
So those are the four low bar classifications.
2:01
Which you can use and
2:02
extrapolate onto the MR image.
2:04
This, an example of a pretty balanced hypertrophy.
2:07
A little more in the back than the front.
2:11
A type 3 pattern of lobar BPH.
