Q

What is the difference between marginal and non-marginal syndesmophytes?

A
marginal syndesmophytes (intervertebral bony bridges, delicate, symmetric) are more commonly seen in ankylosing spndylitis
non-marginal (bulky, discontinuous) syndesmophytes are more commonly seen in reactive arthritis and DISH

Q

What is synoviochondrometaplasia?

Q

What is a marginal erosion and what category of arthritis is it seen with?

A

marginal erosions are irregular with no sclerotic margin
usu at radial margins of 2nd and 3rd MC head in Norgaard/ballcatchers view
seen with RA

Q

What is the significance of widening of the atlantodental interspace?

A

can lead to direct compression of the brainstem or cause neurological damage by excessive kyphosis
• Cervical (MC) spine involvement in 50-80%; few at T/L junction
• Odontoid/dens erosions
• C1-C2 instability → neurologic damage (enlarged; N <5 in child); atlanto-axial subluxations
• Pseudobasilar invagination
• Facet involvement; stair-stepping (anterior-lysthesis; can get with DJD as well)
• IVD involvement

16
Q

Which conditions demonstrate laxity of the transverse ligament?

A

SLE, Downs Syndrome, possible in RA but rare

18
Q

Is SI involvement common in rheumatoid arthritis?

A

No, if present it’s usually minimal sclerosis

uni/bilateral and asymmetrical

19
Q

Describe the radiographic difference between rheumatoid and psoriatic arthritis in the hand and wrist.

A

Psoriatic looks similar to RA except w/o hyperemia
PA: DIP and PIP joints of the hand, Ray pattern (affects all joints of a single digit), ST swelling, Fluffy periostitis, “Pencil in a cup” deformity, marginal erosions, tapered bone ends, asymmetrical with uniform joint space loss
RA: MCPs and PIPs, marginal arosions, radial margins of 2nd, 3rd MC head, DIPs extend, PIPs flex, ulnar deviation at MCP joint

20
Q

What is the gender incidence of rheumatoid arthritis?

A

Onset at 20-60 y.o.; peak 40-50 y.o.

F:M 3:1 until age 40, then 1:1

21
Q

What is the first site of involvement with ankylosing spondylitis?

A

Pelvis: iliac side and lower 2/3 of the SI joint
Spine: thoracolumbar jxn

22
Q

What is the second site of involvement with ankylosing spondylitis?

A

may have peripheral involvement of hips, shoulders, heels but mainly SI and thoracolumbar joint involvement

23
Q

Is sacroiliac involvement usually unilateral or bilateral in ankylosing spondylitis?

A

usually bilateral and symmetrical

24
Q

What is the gender incidence of ankylosing spondylitis?

25
Which condition demonstrates squaring of the vertebral body?
ankylosing spondylitis
26
What is the shiny corner sign?
Increased radiodensity of the corners of the vertebral body related to osteitis, reactive sclerosis that is seen in AS.
27
What is a carrot-stick fracture?
fracture of an ankylosed segment in AS--> usu causes paralysis
28
Which condition demonstrates similar sacroiliac joint and vertebral column findings to AS?
Enteropathic arthropathy, UC, Chrons, Whipples, Salmonella, Shigella, Yersinia
29
Which two seronegative spondyloarthropathies demonstrate non-marginal syndesmophytes and peripheral arthritis?
Psoriatic and Reiters | non marginal syndesmophytes are thicker, not throughout the spine as in AS
30
Reversible deformities of the hand are seen in which condition?
SLE: ie may have ulnar deviation that can be overcome with mm contraction (lax ligaments, not dt bone deformity)
31
What is acro-osteolysis and which conditions demonstrate this finding?
resorption of the extremities as seen in psoriatic arthritis
32
What is the overhanging margin sign and which condition is this seen in?
Pathognomonic finding in Gout--> sclerotic margin outside the joint capsule
33
What structures are primarily involved in CPPD?
(calcium pyrophosphate dehydrate crystal deposition disease) fibrous and hyaline cartilage of the knee, wrist, pubic sym. triangular fibrous tissue in meniscus thick, irregular poor defined menisci
34
What structures are primarily involved in HADD?
(hydroxyapatite deposition disease) | Should and Hip MC; calcification a short distance from insertion of a tendon, MC supraspinatous/ bursa
