This is the case report of a 65-year-old man who experienced left calf pain after spraining his left ankle. On magnetic resonance imaging (MRI), a well-defined fluid collection was identified, with low intensity on T1-weighted images and very high intensity on T2-weighted images. On certain slices, a soft tissue mass in the proximal fibula was identified. Following resection of the fibular lesion, histological examination confirmed a benign tumor with cystic elements, described in the current pathology and radiology literature as juxta-articular myxoma...

Noonan syndrome is a genetic disorder with variable expression of distinctive facial features, webbed neck, chest deformity, short stature, cryptorchidism and congenital heart disease. The association of Noonan syndrome and giant cell granulomas of the mandible is widely reported. However, Noonan syndrome may also be associated with single or multifocal tenosynovial giant cell tumors, also referred to as pigmented villonodular synovitis. We report a child with Noonan syndrome, giant cell granulomas of the mandible and synovial and tenosynovial giant cell tumors involving multiple joints and tendon sheaths who was initially misdiagnosed with juvenile idiopathic arthritis...

PURPOSE: The purpose of this study was to present the long-term results of treatment of localized pigmented villonodular synovitis (LPVNS) comparing two operative procedures of excision of the lesion-the arthroscopic and the arthroscopically assisted mini-open. We hypothesized that the latter approach allowed for treatment of LPVNS with acceptable recurrence rates, complication rates and functional outcomes. METHODS: Between 1990 and 2006, 21 patients with LPVNS were treated with partial synovectomy through an arthroscopically-assisted mini open technique (group A), and 23 patients were treated with an arthroscopic excision of the lesion (group B)...

Pigmented villonodular synovitis (PVNS) is a rare, benign, but potentially locally aggressive and recurrent condition characterized by synovial proliferation and hemosiderin deposition inside the joints, tendon sheaths, and bursae. It usually affects the large joints such as hip, knee, and ankle. We report a case of PVNS of the knee joint in a young female which was treated by subtotal synovectomy alone without the use of adjuvants. At the 14-month follow-up, the patient was pain free and had no signs of disease recurrence...

Sarcoidosis is a systemic inflammatory disorder characterized by non-caseating granulomas, predominantly involving lung, mediastinal lymph nodes and other organs. Synovium involvement is infrequent, and as far as we know, involvement of a periprosthetic membrane has not been reported in the English literature. Intra-articular diffuse tenosynovial giant cell tumor ("conventional diffuse pigmented villonodular synovitis") is an uncommon, locally aggressive neoplasm with few previous case reports in which it arose in periprosthetic tissues after knee arthroplasty...

Pigmented villonodular synovitis (PVNS) is a benign, proliferative disorder of synovium. It often affects the knee, and rarely occurs in the temporomandibular joint (TMJ). This paper reported a 45-year-old male patient with PVNS of the TMJ, who was referred with a chief complaint of slowly growing and painless preauricular mass that was noticed about 1 year. Radical excision and follow-up were conducted, no recurrence and metastasis were noted.

INTRODUCTION: Pigmented villonodular synovitis (PVNS) is a rare, benign proliferative disorder of the synovial membrane that typically presents in adults and affects a single joint. Multifocal PVNS is very rare, particularly in childhood. We reported a rare case of multifocal PVNS affecting over 20 joints in a child. CLINICAL PROCEDURE: A 7-year-old female patient had a 6-month history of multifocal joints swelling with mild pain. She was diagnosed as polyarticular juvenile idiopathic arthritis at a local hospital...

This case concerns a male patient complaining of pain and discomfort in his right elbow, associated with decreased range of motion. Elbow radiography showed an osteolytic lesion in the metaphyseal region of the distal humerus and magnetic resonance imaging showed intra-articular tumor formation with swelling that suggested pigmented villonodular synovitis. Arthroscopic treatment was performed in order to obtain a synovial biopsy and then to carry out total synovectomy. Anatomopathological examination confirmed the diagnosis...

Pigmented villonodular synovitis (PVNS) is a benign disease affecting synovial membranes of young and middle-aged adults. The aggressive treatment of this disorder often involves external-beam irradiation. This study was motivated by the lack of data relating to the radiation exposure of healthy tissues and radiotherapy-induced cancer risk. Monte Carlo methodology was employed to simulate a patient's irradiation for PVNS in the knee and hip joints with a 6 MV photon beam. The average radiation dose received by twenty-two out-of-field critical organs of the human body was calculated...

OBJECTIVES: Benign synovial diseases of the hip including Synovial Chondromatosis (SC) and Pigmented Villonodular Synovitis (PVNS) are devastating diseases. Initially, patients present with hip pain unrelieved by conservative measures. The diagnosis of PVNS and SC are often delayed, leading to progression of joint damage. The purpose of this review is to present the latest on the diagnosis, management, and prognosis of SC and PVNS of the hip. METHODS: An extensive systematic search of MEDLINE and PUBMED Databases was performed...

The foot and ankle are commonly involved in a range of arthritides that affect the joints, bones, and soft tissues. Accurate plain film interpretation can often aid the diagnosis and monitor disease progression and treatment response. Ultrasound and MRI afford superior depiction of the soft tissues, and advances over recent years have centered on early detection of synovitis, enabling earlier diagnosis and treatment. Advantages and disadvantages of the imaging techniques of radiography, multidetector computed tomography, ultrasound, and MRI are discussed, as is optimization of these modalities for the assessment of the anatomically complex joints of the foot and ankle...

INTRODUCTION: Pigmented villonodular synovitis is an uncommon disease characterized by hyperplastic synovium, large effusions and bone erosions. It commonly mimics other conditions. As a result, the diagnosis may remain elusive, as the classic signs of tenderness and effusion are not specific. Occasionally, PVNS presents as a popliteal cyst, which may divert attention from intra-articular pathology. In this article, we describe a case of pigmented villonodular synovitis that presented with a popliteal cyst as the chief problem...

BACKGROUND: Isolated limb perfusion (ILP) is an established and effective treatment for advanced melanoma and soft tissue sarcomas of the extremities with a high overall response rate. The aim of this study was to describe our experience of ILP for more rare types of tumours. METHODS: Patients with Merkel cell carcinoma (MCC) (n = 4), squamous cell carcinoma (SCC) (n = 2), B-cell lymphoma (n = 1), desmoid tumours (n = 3), pigmented villonodular synovitis (PVNS) (n = 1) and giant cell tumour (n = 1) were treated with ILP and analysed retrospectively...

Pigmented villonodular synovitis (PVNS) is a rare pseudotumoral proliferative benign condition of unknown etiology, affecting synovial joints. It can also develop in the synovial bursae and in the tendon sheaths. It usually affects large joints, such as the knee and the hip. Ankle is a rare location, with only a few cases reported in the literature. We report a case of a 52 year old patient with a PVS of the right ankle. She received a subtotal synovectomy. After 2 years of follow-up there was no clinical recurrence...

Pigmented villonodular synovitis (PVNS) is a rare and benign proliferative disorder of synovium with potentially locally aggressive growth and invasion of the bone. Occurring within the joints, tendon sheaths, and bursae, it is most commonly a monoarticular disease affecting large joints. In particular, most cases of PVNS occur in the knee. PVNS of the temporomandibular joint (TMJ) is a highly rare disorder, with approximately 60 cases reported. Herein, we present a unique case of an elderly male presenting with ear pain and subsequently diagnosed with PVNS of the TMJ with a history of trauma to the area...

Pigmented villonodular synovitis (PVNS) is a benign joint disease best characterized on magnetic resonance imaging (MRI). The role of fluorine 18 fluorodeoxyglucose ((18)F-FDG) position emission tomography-computed tomography (PET-CT) in the diagnosis or characterization remains unclear. PVNS displays as a focal FDG avid lesion, which can masquerade as a metastatic lesion, on PET-CET. We present a case of PVNS found on surveillance imaging of a lymphoma patient.
