However, 2 conditions-synovial chondromatosis and tenosynovial giant cell tumor (pigmented villonodular synovitis)-occur in the lining (synovium) of joints. (msdmanuals.com)
Diffuse tenosynovial giant cell tumor has a high local recurrence rate that often leads to further surgery and morbidity. (msdmanuals.com)
OBJECTIVE: This study investigated radiographic images and the differential diagnosis of intracranial diffuse tenosynovial giant cell tumor (D-TGCT) in order to better understand the disease and improve the rate of preoperative diagnosis. (bvsalud.org)
Pigmented villonodular synovitis (PVNS), also known as diffuse tenosynovial giant cell tumor, is a benign proliferative disorder of uncertain etiology that affects synovial lined joints, bursae, and tendon sheaths (see the images below). (medscape.com)
Must be differentiated from diffuse tenosynovial giant cell tumor. (tumorsurgery.org)
Tumors2
The tumors arise from neoplastic synovial cells that overexpress a growth factor CSF-1 (colony stimulating factor-1). (msdmanuals.com)
Typically occur in the hand where they represent the second most common type of soft tissue tumors after synovial ganglions. (bvsalud.org)
Proliferative1
Arthroscopy revealed characteristic findings of proliferative synovial disease with numerous loose bodies (Fig 3). (medscape.com)
There is a malignant soft tissue tumor called synovial sarcoma that arises in different types of soft tissue but is not of synovial origin and seldom occurs inside of a joint. (msdmanuals.com)
MRI also can identify many types of soft-tissue abnormalities about the hip, including synovial cysts, periarticular bursitis, soft tissue masses and articular abnormalities such as synovial chondromatosis. (dieutridau.com)
Joints2
The tumor may be nodular (focally localized) in smaller joints of the hands, feet, and knee, or, more commonly, diffuse in larger joints such as the knee and hip. (msdmanuals.com)
The Synovial Joints On-Demand Conference Series is included as part of a 1-year and 2-year annual subscription to MRI Online. (mrionline.com)
Tendon2
Two primary forms of PVNS are described: a diffuse form that affects the entire synovial lining of a joint, bursa, or tendon sheath, and a rare focal, or localized, form. (medscape.com)
GCTTS present as localized or diffuse proliferation of synovial-like cells, giant cells, inflammatory cells and xanthoma cells along tendon sheaths. (tumorsurgery.org)
Lesions2
[ 1 , 2 ] Localized lesions are more common than diffuse involvement, comprising 77% of total lesions in one review, with a 3.3:1 localized-to-diffuse predominance ratio. (medscape.com)
PVNS lesions on histology demonstrate synovial cell proliferation, xanthomatous cell accumulation, hemosiderin deposition, and the presence of multinucleated giant cells. (medscape.com)
Knee1
The knee is a complex synovial joint that can be affected by a range of pathologies: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. (thelaunchqueen.com)
Bodies5
Care was taken with a meticulous synovial debridement with thorough removal of the loose bodies. (medscape.com)
While most of the fragments were free loose bodies, some were transitional from the intrasynovial phase, classic in synovial chondromatosis. (medscape.com)
Double-contrast arthroscopic computed tomographic scan confirms intra-articular location of loose bodies, with multiple filling defects characteristic of synovial chondromatosis. (medscape.com)
Both are treated by open synovectomy and, for synovial chondromatosis, removal of any intra-articular bodies and metaplastic synovium. (msdmanuals.com)
Treatment of synovial chondromatosis may be symptomatic, but if mechanical symptoms are prominent, arthroscopic or open removal of the bodies or synovium is warranted. (msdmanuals.com)
Joint1
On physical examination of the elbow, mild synovial thickening was palpable in the lateral soft spot and diffuse joint line pain was present with range of motion. (medscape.com)
Range1
On physical examination, he had mild palpable synovial thickening and pain through range of motion, which was limited from 35° of extension to 132° of flexion with 45° of supination and 60° of pronation. (medscape.com)
