Neoplastic Disorder Choreas

HIDE

0:00

Here's our 67-year-old man with known

0:03

Huntington's chorea and a family history thereof.

0:06

He's got some mild movement abnormalities.

0:09

We follow the cingulate sulcus all the

0:11

way back to the supermarginal sulcus.

0:15

And then right in front of that is this kind of

0:17

obliquely oriented sulcus that

0:19

delimits the motor area.

0:22

And then in front of the motor area

0:24

is the supplementary motor area,

0:26

especially as we go towards the midline,

0:28

and that supplementary motor area,

0:30

which is an inhibitory area,

0:32

a control station for the rest

0:35

of the body is atrophic.

0:37

I want to talk about chorea in

0:38

neoplastic brain disease.

0:40

And I'll bet you can't guess which neoplasm

0:43

is most prone to present with chorea.

0:45

It's the one that likes to infiltrate the deep

0:48

recesses of the brain and the basal ganglia

0:50

and the subthalamic nucleus,

0:52

namely periventricular lymphoma,

0:55

if you're getting asked a question about it.

0:57

Any tumor, though,

0:58

that disrupts the striato-pallido-thalamo-cortical

1:03

motor circuitry can do it,

1:05

but lymphoma is the classic.
