“…In CC changes of synovial membrane (thickening, synovial villi, effusion) were similar to those found in inflammatory diseases (14)(15)(16)(17); those findings show that CC is a disease with inflammatory factors which often attack the AC with degenerative changes caused by old age of patients (18)(19). Moreover synovial phlogosis may increase cartilaginous damage and it could justify the thinning of cartilage in CC, which is similar to that of serious osteoarthritis.…”

Chondrocalcinosis: Sonographic study of the knee

Summary Sonography of the knee was performed in 28 patients with chondrocalcinosis and in 46 normal subjects. In each joint the authors examined synovial membrane, articular cartilage of femoral condyles, synovial fluid and menisci; they also searched for Baker's cysts. A significant thickening of synovial membrane was present. In 43 joints sonography showed linear hyperechoic images within condylar cartilage; they were parallel to bone surface and were interpreted as calcifications because of the coincidence with radiographic images. A significant thinning of articular cartilage was also found. Sonography of the knee is a useful method of examination for the evaluation of articular changes in chondrocalcinosis.

Pigmented villonodular synovitis of the knee: computed tomographic appearances

Five patients with pigmented villonodular synovitis (PVNS) of the knee demonstrate the value of preoperative, contrast medium-enhanced CT scanning. The technique is shown to be particularly useful in locating recurrent lesions and in demonstrating that popliteal and posterior calf masses are due to PVNS affecting the knee joint itself. In two of the five patients PVNS was not considered a possibility before the CT scan, and none had evidence of bone erosion on plain radiographs. In none of the patients was the unenhanced CT scan able to demonstrate evidence of decreased radiolucency due to fat within the tumour or density greater than the adjacent skeletal muscle, indicating haemosiderin deposits.

“…The incidence rate of PVNS is low and relatively rare in clinical practice. Hence the sonographic manifestations of PVNS at home and abroad were mostly case reports 3–5 . Although the application value of ultrasonography in the early diagnosis and activity assessment of RA has been widely confirmed 6–8 .…”

“…Hence the sonographic manifestations of PVNS at home and abroad were mostly case reports. [3][4][5] Although the application value of ultrasonography in the early diagnosis and activity assessment of RA has been widely confirmed. [6][7][8] There were few studies on the value of ultrasonography in differentiation of PVNS and active RA, moreover there was no relevant report on the application of superb microvascular imaging (SMI) and contrast-enhanced ultrasound (CEUS) in the differential diagnosis of the two diseases.…”

Objectives This is a prospective study to evaluate the clinical value of high‐frequency ultrasound (HFUS), superb microvascular imaging (SMI), and contrast‐enhanced ultrasound (CEUS) in differentiation of pigmented villonodular synovitis (PVNS) and highly active rheumatoid arthritis (RA). Methods Twenty PVNS patients and 24 active RA patients were selected to undergo HFUS, SMI, and CEUS examinations. The characteristics of HFUS, SMI, and CEUS in PVNS and RA were compared, and the differential diagnosis performances of HFUS, SMI, and CEUS in PVNS and RA were evaluated by receiver operating characteristic (ROC) analysis. Results There were statistically significant in joint effusion, synovial thickness, synovial morphology, synovial echo, synovial vessel shape, synovial enhanced direction, and enhanced pattern between PVNS and RA (P < .05). However, no statistically significant were found in bone erosion, synovial boundary, blood signal grading of synovium, synovial enhanced strength, and CEUS quantitative parameters (including PI, TTP, S, MTT, and AUC) (P > .05). The AUC of HFUS, SMI, and CEUS for differential diagnosis PVNS and RA were 0.832, 0.675, and 0.817, respectively. The AUC of HFUS + SMI, HFUS + CEUS, SMI + CEUS, HFUS + SMI + CEUS were 0.923, 0.940, 0.817, and 0.940, respectively. The AUC of HFUS + SMI and HFUS + CEUS was higher than that of each alone (P < .05). Conclusions HFUS, SMI, and CEUS can be used as supplementary methods for diagnosis and differential diagnosis in PVNS and active RA. What is more, the combination of HFUS + SMI and HFUS + CEUS was suggested.
