SERONEGATIVE ARTHRITIS
Inflammatory arthritis that lacks the presence of rheumatoid factor, including ankylosing
spondylitis, psoriatic arthritis, Reiter’s syndrome, and enteropathic arthritis.
FIVE SUBGROUPS OF SERONEGATIVE ARTHRITIS ARE
DISTINGUISHED:
•ankylosing spondylitis: ~90% HLAB27 positive
•psoriatic arthritis: ~60% HLAB27 positive 1
•reactive arthritis: ~85% HLAB27 positive
•enteropathic arthritis (i.e. extraintestinal manifestation of IBD)
•undifferentiated spondyloarthritis

Chronic inflammatory disorder affecting the articulations, ligaments, and tendons of the
spine and pelvis
Unknown etiology
Predominantly affecting younger adult males.
Involves the axial skeleton.
Characterized by
1. Articular bony ankylosis
2. Ligamentous ossification
3. Enthesopathy.
CLINICAL FEATURES
Chronic Low Back Pain In Young Men
Initially Involves Sacroiliac Joints Bilaterally, Then Ascends The Spine.
Skip Involvement Can Occur
Pain And Tenderness Over Bony Protuberances
Morning Stiffness
Peripheral Involvement Of The Large Joints Occurs In Up To 50% Of Patients, While
Up To 30% Will Have Involvement Of The Smaller Joints.
Complications Include Iritis, Aortitis, Valvular Incompetence,Aneurysms, Conduction
Blocks, Upper Lobe Pulmonary Fibrosis, Inflammatory Bowel Disease, Renal Failure
Owing To Secondary Amyloidosis, Carrot-stick Fractures, Andersson’s Lesion, And
Prosthesis Ankylosis.
Laboratory Findings Will Show Esr Elevation, Depending On Disease Activity, Mild
Anemia, Positive Hla-b27 (90%; 6% False Positive), And Negative Rheumatoid
Arthritis Latex(Seronegative)
RADIOLOGIC FEATURES
Initial changes occur in the sacroiliac joints, then at the thoracolumbar and
lumbosacral junctions; spine shows progressive changes, generally in an ascending
manner
Major signs are osteoporosis, erosions with surrounding sclerosis, and bony ankylosis.
Enthesopathy can be seen.
Sacroiliac joint: involvement is usually bilateral and symmetric.
Cervical spine: findings include decreased lordosis, body and facet fusion,
atlantoaxial instability and odontoid erosions, decreased vertebral body size in
lower levels, tapered spinous processes, and intervertebral foramen enlargement and
is the most common area for carrot-stick fractures (C5–T1).
Thoracic spine: changes include syndesmophytes, facet and costal fusion, increased
kyphosis, and osteoporosis.
Lumbar spine: changes include decreased lordosis and sacral angle, facet fusion,
(trolley track sign), bamboo spine; early involvement (Romanus lesion, shiny corner)
common at thoracolumbar junction.
Pelvis: abnormalities include symphysis pubis changes, similar and parallel sacroilliac
involvement.
Hip: involvement is usually bilateral and reasonably symmetric. Signs
include small osteophytes, subchondral cysts, and uniform loss of joint
space, with axial migration of the femoral head. May eventually ankylose .
Shoulder: involved in 30% of cases and is usually bilateral. Signs include
surface erosions and, occasionally, a hatchet erosion at the superolateral
aspect of the humerus and uniform loss of joint space. Enthesopathy at
coracoclavicular ligamentous attachments at inferior clavicular surface.
Foot: manifestations localize to the calcaneus, with enthesopathy,
especially at Achilles and plantar insertions. Spurs usually fluffy and
irregular compared with degenerative spurs

SACROILIAC JOINT.
Stage 1. Pseudo-Widening of the Joint Space
Stage 2. Erosive and Sclerotic Changes.
Stage 3. Ankylosis.
STAGE 1. PSEUDO-WIDENING OF THE JOINT
SPACE
STAGE 2. EROSIVE AND SCLEROTIC CHANGES.
STAGE 3. ANKYLOSIS.

PSORIATIC ARTHRITIS
Psoriasis is a common skin disorder associated with joint disease and
characterized by peripheral joint destruction and deformity: sacroiliitis and
non-marginal syndesmophyte formation
ROLE OF CONVENTIONAL IMAGING IN SERONEGATIVE SPONDYLOARTHRITIS.pptx
CLINICAL FEATURES
Age 20–50 years; equal sex ratio.
Skin lesions characteristic, usually on extensor surface (knees, elbows, back),
also scalp, abdomen, and genital region. Lesions are well-defined, dry, raised,
red and silvery, scaly patches
Presence of nail changes seen in 80% of arthritis patients.
Arthritis is usually in peripheral joints, especially DIP joints
Whole finger or toe may show soft tissue swelling (sausage digit).
ESR normal (except in acute phase), negative rheumatoid arthritis latex,
positive HLA-B27 in 75% of patients with sacroiliac involvement and 30% in
peripheral arthritis.
PATHOLOGIC FEATURES
• Fundamentally similar to rheumatoid arthritis, but pannus affects cartilage less and
erosions are smaller and
slower in their development.
• Adjacent to erosions, there is often prominent periosteal new bone that is typically
fluffy.
• Erosions often will progressively taper the end of an entire bone.
• Large amount of intra-articular fibrous tissue widens the joint and results in eventual
bony ankylosis.
• No subcutaneous nodules or rheumatoid factor
RADIOLOGIC FEATURES
General features include soft tissue swelling, normal bone mineralization, erosions, and
tapered bone ends, prominent juxta-articular fluffy periostitis, and jointspace widening or
bony ankylosis.
• Hands and feet: asymmetric involvement, ray pattern, most commonly involves DIP joints,
no osteoporosis, mouse ears sign, widened joint space owing to fibrous tissue deposition
and bone resorption, pencil-in-cup deformity, opera glass hand deformity, no ulnar
deviation.
• Sacroiliac joint: involved in up to 50% of psoriatic arthritis patients, usually bilateral but
asymmetric and unusual to be narrowed and ankylosed.
• Spine: atlantoaxial subluxation and dislocation, normal apophyseal joints (except in the
cervical spine), syndesmophytes of two types—non-marginal, marginal (non-marginal are
the most common)—broad-based and tapered, asymmetric, unilateral, and most common in
the upper lumbar and lower thoracic spine

ENTEROPATHIC ARTHRITIS
ROLE OF CONVENTIONAL IMAGING IN SERONEGATIVE SPONDYLOARTHRITIS.pptx
CLINICAL FEATURES
Usually begins in young adults.
• Peripheral arthralgias, with rapid resolution and no residual sequelae common,
especially knee, ankle, elbows and wrists.
• Spinal involvement identical to ankylosing spondylitis seen in up to 10% of ulcerative
colitis and, to a lesser extent, regional enteritis and may precede onset of intestinal
disease.
• Increased incidence of HLA-B27.
PATHOLOGIC FEATURES
Pathogenesis unknown, but most likely related to formation of immune complexes,
resulting in inflammatory joint involvement.
RADIOLOGIC FEATURES
Identical to ankylosing spondylitis—bilateral sacroiliitis, leading to
ankylosis.
• Syndesmophytes and apophyseal ankylosis in the spine.
• Occasional peripheral long-bone periostitis (hypertrophic
osteoarthropathy).
REITER’S SYNDROME
A triad of urethritis, conjunctivitis, and polyarthritis
usually following sexual exposure or, less commonly, certain types of dysentery.
CLINICAL FEATURES
Affects males 50:1, 18–40 years of age.
• Arthritis predominantly of lower extremity, especially foot, calcaneus (lover’s heels),
ankle, knee, sacroiliac, and thoracolumbar spine; residual deformities if chronic.
• Bilateral conjunctivitis, non-specific urethritis, mucocutaneous lesions (keratodermia
blenorrhagicum).
• Laboratory signs of inflammation; positive HLA-B27 in 75% of cases.
RADIOLOGIC FEATURES
Swelling, osteoporosis, uniform loss of joint space, erosions,
periostitis.
• Specific target sites: forefoot, calcaneus, ankle, knee, sacroiliac,
spine.
• Foot: metatarsophalangeal and interphalangeal joints.
• Calcaneus: plantar and Achilles insertions.
• Ankle: loss of joint space, swelling, periostitis.
• Sacroiliac: erosions, sclerosis, loss of joint margin, asymmetric
and often unilateral.
• Spine: thoracolumbar, asymmetric, skip non-marginal
