Bilateral synovial chondromatosis in the knee joint with both intra and extra-articular diseases

Abstract

Synovial chondromatosis is a rare disease of unknown etiology. It usually occurs unilaterally in the large joints like the knee, but may occur in the shoulder, elbow, hip, ankle and temporomandibular joints. The disease is usually intracapsular, but can also be extracapsular on rare occasions. The diagnosis of synovial chondromatosis is given after an anamnesis, physical examination and radiographic examination. However, the diagnosis is obtained after histological examination of the synovial tissue. We report an unusual presentation of bilateral synovial chondromatosis in the knee joint, with both intra and extracapsular localization. never described in the literature. Although synovial chondromatosis is described as a benign disease, it can be very destructive and debilitating. These lesions can mimic a malignant tumor and present a diagnostic problem.

Bilateral generalised synovial chondromatosis of the knee: Bone scintigraphic demonstration with radiologic correlation

“…Bilateral and generalized synovial chondromatosis of the knee is extremely rare, and only a few cases showing radiologic findings of disease has been reported. [ 7 8 ] This is a rare presentation of generalized synovial chondromatosis involving both knees which demonstrated on 99m Tc-MDP bone scintigraphy with X-ray and CT correlation.…”

Temporomandibular Joint Synovial Chondromatosis: A Rare Case

“…Therefore, localization, nature and changes in the neighboring structures can also be detected by computed tomography (CT) and MRI examinations, especially in the stages before ossification. 16,17 CT can show better calcified nodules and bone erosions than direct radiographs. Because of the superior soft tissue contrast and multi-planar imaging features, the typical image detected on MRI is joint articular effusion and intraarticular, intrabursal and tenosynovial soft masses with nodules.…”

Primary synovial chondromatosis: an elemental investigation of a rare skeletal pathology

“…Applying Milgram's staging to the results from the cadaveric dissection in this study, a diagnosis of bilateral, extraarticular PSC could be postulated: cartilaginous deposits found in the synovial membrane of the left semimembranosus bursa suggest a possible stage I disease state, with the loose bodies in the right indicating stage III. Bilateral, extraarticular presentations of PSC have been reported [28] but are exceedingly rare. More research is required to investigate potential underreporting of bilateral cases when staging is asymmetrical, with the more conspicuous side possibly overshadowing the other.…”
