Describe the pathophysiology and clinical features of primary and secondary synovial chondromatosis.
Describe and demonstrate multimodality-imaging features of synovial chondromatosis.
Describe the complications of primary synovial chondromatosis and their imaging correlates.
Discuss other intra-articular/peri-articular pathologies within the differential diagnosis with relevant distinguishing features on imaging
Synovial chondromatosis refers to the presence of intra-articularcartilaginous loose bodies,
whichmay ormay notbe calcified/ossified.
It is known by several other names,
namely synovial osteochondromatosis,
articular ecchondrosis and synovial chondrosis.
A distinction should be made between primary and secondary synovial chondromatosis.
It should also be differentiated from other intra-articular conditions,
which may have a similar appearance on imaging.
Primary synovial chondromatosis (PSC)is a relatively uncommon condition,
(incidence of 1:100,000) thattypically affects patients in the third to fifth decades of life.

Imaging findings OR Procedure Details
Primary synovial chondromatosis (PSC) imaging findings:
This is oftenabnormal in 70% of cases and may demonstrate the following features:
Innumerable intra-articular calcifications of uniform size,
which are evenly distributed throughout the joint Fig. 1 (or less commonly tendon or bursa Fig. 5Fig. 6).
Chondroid ring-and-arc pattern of mineralisation is common,
which can progress and undergo ossification.
In rare cases the chondral bodies can coalesce to form la arger,
conglomerate mineralised mass.
The joint space should be maintained,
however in chronic disease...
Synovial chondromatosis can have a varied appearance depending on whether it is primary or secondary,
intra or extra-articular or on the phase of the disease.
CT and MRI have characteristic appearances and in equivocal cases,
biopsy can aid diagnosis particularly if other intra-articular causes are suspected.
