Causes of Bursitis

HIDE

0:00

<v ->Now the causes of bursitis are many.

0:03

I mentioned that at the beginning.

0:04

I'll show you a few examples.

0:06

This is gout.

0:07

And generally when you're dealing with gout,

0:09

there'll be areas of persistent low signal,

0:12

even on fluid-sensitive sequences.

0:15

Here's another example of gout

0:16

involving the olecranon bursa.

0:19

Here is gout involving the deep infrapatellar bursa.

0:23

We'll be talking more about that later on.

0:27

When we deal with septic bursitis,

0:29

there are two particular bursae

0:31

that are most commonly involved.

0:33

The olecranon bursa,

0:34

and this one, which is the prepatellar bursa,

0:37

here communicating with the superficial infrapatellar bursa

0:42

that's tended with fluid.

0:44

And you can see the peripheral enhancement

0:47

with the gadolinium.

0:49

And another example.

0:50

This is septic olecranon bursitis,

0:53

which led to contamination of the olecranon,

0:56

hence osteomyelitis,

0:59

which then led to contamination of the joint.

1:02

And that would be then a septic arthritis.

1:06

And we deal also with an entity known as

1:09

hemorrhagic bursitis.

1:11

And this is typically associated

1:14

with coagulation abnormalities.

1:16

And we see it most commonly in the olecranon bursa,

1:20

but the other location that is fairly common shown here

1:24

is the prepatellar bursa.
