Question 24

ABCDE da artrite psoriásica

Answer 24

Articular: small marginal bone erosions, arthritis mutilans with acro-osteolysis and pencil-in-cup deformities, joint subluxation, interphalangeal ankylosis, sacroiliitis (frequently asymmetrical).

Bone: bone productive changes, periostitis, Ivory phalanx (distal phalanx dig 1), spondylitis (asymmetrical paravertebral ossifications).

Cartilage: joint space narrowing

Distribution: see illustration, asymmetric and predominantly peripheral.

Extra findings: skin lesions, telescoping fingers.
Soft tissue: Enthesitis, dactylitis (sausage digit), onycholysis (the nail separates from the skin).

Question 25

ABCDE Artrite reativa

Answer 25

Articular: in later disease ill-defined erosions like psoriatic arthritis (typically calcaneus is involved) Bone: Bone proliferation but also juxta-articular osteoporosis and enthesopathy/enthesitis Cartilage: uniform joint space narrowing. Distribution: asymmetric, see illustration Extra findings: usually triggered by a preceding infection Soft tissue: swelling soft tissue (also sausage digit)

Question 26

Question 27

ABCDE da gota

Answer 27

Articular: “punched out “ erosions > 5 mm, that spare part of the joint with an overhanging edge of new bone. Lesão saco bocado Bone: bone mineralization is normal. Chondrocalcinosis or osteonecrosis can occur. Cartilage: joint effusion (earliest sign), preservation of joint space Distribution: see illustration, there is a predilection for peripheral joints. Most often it has an asymmetric, random distribution. Extra findings: usually male, hyperuricemia Soft tissue: tophi: pathognomonic, eccentric nodular soft tissue swelling due to crystal deposition around the joints is common. These may be hyperdens due to the crystals and may calcify. Olecranon and prepatellar bursitis.
