1

soft tissue swelling RA

2

sausage digits in psoriatic arthritis

3

gout

4

demineralized bone in RA

5

increased bone density in psoriatic arthritis

6

uniform joint space narrowing

think INFLAMMATION: RA, septic arthritis, seroneg spondyloarthropathy

7

non-uniform joint space narrowing

think DEGENERATIVE: OA or CPPD

8

left RA, right OA

9

in what rheumatologic conditions are there only small or focal defects (joint space preserved)?

gout, pigmented villonodular synovitis, "early" OA

10

where do marginal erosions happen first?

"uncovered" bone at margin of joint

11

in which conditions do you see marginal erosions?

RA, psoriatic arthritis, reactive arthritis

12

RA w/ marginal erosions

13

gout:

  • erosions may be remote from joint
  • overhanging edge of bone

 

14

in what conditions do you see subluxation

with erosions: RA

w/out erosions: SLE

15

subluxation w/out erosion = lupus

16

bone production findings

OA: osteophytes, subchondral bone

Seroneg spondy: periosteal new bone, ankylosis

Gout: overhanging edge

17

subchondral bone - OA

18

reactive arthritis

19

left: ankylosing spondylitis

right: DISH

21

calcifications: pyrophosphate arthropathy or normal aging

22
