Pigmented villonodular synovitis (PVNS) is an uncommon musculoskeletal tumor that is typically benign and often diagnosed radiologically by magnetic resonance imaging (MRI). Fluorodeoxyglucose (FDG)-uptake positron emission tomography (PET) is an imaging tool primarily used in oncology to evaluate malignancy. FDG measures metabolic activity with standardized uptake value (SUV). A high SUV is su...

Background: Pigmented villonodular synovitis (PVNS) is a benign but locally aggressive proliferative disorder, commonly arising from the synovium of long bone joints, tendon sheaths and bursae. PVNS is rarely found in the temporomandibular joint (TMJ), with around 52 reported cases in the current English literature. It is most commonly found in the knee joint, followed by the hip, ankle, small ...

PURPOSE We report 10 years' experience in arthroscopic treatment of pigmented villonodular synovitis (PVNS) of the knee in a series of patients affected by the localized or diffuse form of the disease. The purpose of the study is to critically examine the results of arthroscopic synovectomy in the knee affected by PVNS, to determine the safety and effectiveness of the procedure. TYPE OF STUDY...

Pigmented Villonodular Synovitis (PVNS) is a relatively rare, benign proliferation lesion of the synovium of large joints. The etiology is varied and unclear. We had report a 79-year-old woman had PVNS after 14 years right hip arthroplasty with metal prosthesis. Here we report another 4 patients had PVNS after arthroplasty. The second one had PVNS in the 2(th) year after hip arthroplasty with b...

Tuberculosis (TB), once a disease confined to undeveloped or developing nations is currently in resurgence, which is attributable to pandemic human immunodeficiency virus (HIV) infection and immigration from endemic areas. Tuberculous arthritis is difficult to diagnose early because of its atypical insidious clinical manifestations and nonspecific imaging findings. TB is also known as the 'grea...

BACKGROUND We present a case of a 51-year-old male patient with pigmented villonodular synovitis (PVNS) of the left temporomandibular joint (TMJ) that initially presented as a slow-growing left facial mass. Upon further workup, a contrast-enhanced CT scan demonstrated an expansile soft tissue mass in the left TMJ. METHODS The lesion was diagnosed through fine-needle aspiration biopsy. The pat...

Two elite female athletes presented with anterior knee pain with range of motion and reproducible tenderness to palpation. Diagnostic arthroscopy was performed in both cases resulting in excision of a nodular pigmented villonodular synovitis (PVNS) in the first patient and scar tissue in the second patient. Correct diagnosis of anterior knee pain in the elite female athlete can present a challe...

Background. Pigmented villonodular synovitis (PVNS) is a rare benign tumor affecting large joints and prompts excision to prevent local destruction of the joint. The purpose of this case report is to describe two differing surgical approaches for management of PVNS of the hip in patients requiring concomitant treatment for additional hip pathology. Methods. This report discusses the presentatio...
