A case report on synovial chondromatosis in adult with secondary arthritis

Abstract

Introduction: Primary synovial chondromatosis (PSC) is a rare, usually monoarticular disorder of synovial joints. PSC is characterized by the formation of osteocartilaginous nodules in the synovial connective tissue. Case Description: We report a case of 65 year old male with Primary synovial chondromatosis in left hip. On clinical examination, patient had restricted abduction, rotational movements and a flexion deformity of 30 degree in left hip with an antalgic gait. Patient gives a history of difficulty in walking since last 10 years. The patient had taken some treatment to relieve his pain which were relieved temporarily. Patient's symptoms were only of pain when he started observing a change in gait and progressive deformity since last 2 years. The patient has not taken any definitive treatment for his complaints. Ultrasound examination of the left hip revealed joint effusion and demonstrated numerous multiple hyperechogenic foci. Plain radiographs anteroposterior view of pelvis with both hips show multiple soft tissue shadows with multiple irregular shaped calcification around femoral neck. Conclusion: Rounded lesions seen in the joint should always be investigated histopathologically and on the basis of non-invasive investigations for Synovial Chondromatosis. The imaging appearance of PSC appears sufficiently unique to allow its differentiation from other causes of intra-articular pathology.
