SPONDILITIS TB
• Increased kyphotic curve of thoracic
spine with angulation at T9-10 level.
• Collapsed T9 and T10 vertebral bodies
with obliteration of T9-10 intervertebral
disc space.
• Bilateral paraspinal soft tissue (arrows).
• Diagnosis: Tuberculous spondylitis
RADIOGRAPHS: EROSIONS
• Terdapat area lusen dalam aspek lateral badan vertebra yang berdekatan (erosi)
• Penyempitan ruang diskus
• Central lucency with surrounding sclerosis suggesting chronic infection
RADIOGRAPHS: ENDPLATE DESTRUCTION
RADIOGRAPHS: ATYPICAL FEATURE
CT : CALCIFICATION

Kerusakan badan vertebral yang luas menyebabkan fragmen tulang.
OSTEOARTHRITIS (OA)
OA of hip
• Marginal osteophyte formation (solid white arrows)
• Subchondral sclerosis (solid black arrows)
• Subchondral cyst formation (dotted black arrows)
PRIMARY OA OF HIP AND KNEE
PRIMARY OA OF THE HANDS
SECONDARY OA OF HIP
There is a marked discrepancy between the
two hips with severe and advanced
osteoarthritis of the right hip (black arrow)
and a relatively normal left hip (white arrow).
CHARCOT ARTHROPATHY (NEUROPATHIC JOINT)
The hallmark findings of a Charcot joint, however, are
fragmentation of the bones surrounding the joint, which
produces numerous small, bony densities within the joint
capsule (white arrows), and joint space destruction (black
arrows). The most common cause of a Charcot joint of
the knee is now diabetes.
CALCIUM PYROPHOSPHATE DEPOSITION DISEASE
A, Hook-shaped bony excrescences along the 2nd and 3rd metacarpal heads are a common finding in CPPD (white arrows). The
radiocarpal joint is narrowed (black arrow). B, In the wrist, characteristic findings include calcification of the triangular fibrocartilage
(white arrow), separation of the scaphoid (S) and the lunate (L) (scapholunate dissociation), and collapse of the capitate (C) toward
the radius (black arrow), called scapholunate advanced collapse (SLAC).
EROSIVE OSTEOARTHRITIS
The erosions are typically centrally located
within the joint (black arrows) and, combined
with the small osteophytes associated with the
disease (white arrows), produce what has been
called the gull-wing deformity.
RHEUMATOID ARTHRITIS (RA)
A, In the hand, the erosions of metacarpalphalangeal (MCP) joints (white arrows)
B, In the wrist, erosions of the carpals (dotted white arrow), ulnar styloid (solid white arrow), and narrowing of
the radiocarpal joint space (solid black arrow) are commonly seen.
GOUT
The hallmark of gout is the sharply marginated Olecranon bursitis in gout.
erosion, which may have a sclerotic border (white • Large soft tissue mass around elbow shown by white
arrows). The overhanging edges of gouty erosions have arrows
been called rat-bites. • Erosions adjacent to the elbow joint (black arrow)
PSORIATIC ARTHRITIS
Telescoping of one phalanx into another (pencil-in-cup deformity)
ANKYLOSING SPONDYLITIS
• Solid white arrow points to bony overgrowth at the ischial
tuberosity
• Bilaterally symmetrical sacroiliitis is the hallmark of
ankylosing spondylitis. This eventually leads to bony fusion
or ankylosis of the sacroiliac joints until they disappear as
joints altogether (solid black arrows)
• The symphysis pubis is also ankylosed (dotted black arrow)
ANKYLOSING SPONDYLITIS OF SPINE
• Bony bridges joining the corners of adjacent
vertebrae called syndesmophytes (white arrows).
• Progressive ossification connecting adjacent
vertebral bodies produces the bamboo-spine
appearance.
