Laboratory studies:
erythrocyte-sedimentation rate is increased suggesting infection, it is normal to condromatoza primary and secondary to theincreased
C-reactive protein is evaluated if it suggests possible infection, the levels are normal in primary condromatoza are high in thesecondary
differential blood count may suggest inflammation-
Lyme titer-endemic areas is important if infection is suggested.
Imaging Studies:
Radiography is often diagnostic. Plain radiograph often showscharacteristic elements: body in multiple calcified bone or joint or bursa. When not calcified fragments are not observed, requiringartrografice studies to demonstrate their presence. Pressureerosions and cyst formation observed in the adjacent bones.Artrogramele tomography and CT are useful for demonstratingintra-articular noncalcificati corpus.
MRI shows round multiple corpora hipointensi izointensi or facemuscles. Some body can be completely free or intra-articular,while others are adherents of the synovial surface. Intravenous administration of gadolinium allows differentiation epensamentelorarticular synovial hyperplasia.
Histological examination: the thick formations describe HEstaining, Vilo synovial membrane crowded with islands ofchondrocytes. Chondrocytes in the nodules are arranged inclusters. Shows atypical chondrocytes with moderate nuclearpleiomorfism, large nuclei, binucleere. Mitosis are rare. If there iscalcification is distributed unevenly in spots. In late stages thenodules may undergo ossification endocondrala vascular invasionand bone formation.
The differential diagnosis is made with the following conditions:vilonodulara synovitis pigmented tubercle and corpus ofrheumatoid arthritis, synovial hemangioma.
