Pigmented villonodular synovitis (PVNS) is a benign synovial tumor of unknown etiology with a predilection for the large joints of the appendicular skeleton. The poor prognosis for patients with hip disease is partially imparted by current surgical techniques. Recent advances in hip arthroscopy technique and instrumentation may enable arthroscopic treatment for PVNS in the hip. The authors repo...
Pigmented villonodular synovitis (PVNS) is a rare, benign, proliferative disease of the synovial membrane of joints, tendon sheaths, and bursas. Joint aspiration typically yields hemorrhagic or xanthochromic/serosanguinous (brown, murky) fluid. We describe a case of PVNS that presented as an acute, painless, nontraumatic right knee effusion with clear synovial fluid on arthrocentesis. Initial m...
Pigmented villonodular synovitis (PVNS) is a benign proliferative joint disease with an uncertain etiology that uncommonly involves the spine. We present a case of PVNS involving the lumbar spine. A 38-year-old male developed back pain and pain in both legs caused by a mass in the L4 region of the right lamina. After gross total tumor removal, the symptoms improved. The pathological finding was...
Abtract: Although most common in the hip and knee joints, pigmented villonodular synovitis (PVNS) has also been reported to occur in the ankle. The distinctive appearance of PVNS on magnetic resonance imaging (MRI) has proven to be useful in both the diagnosis and treatment of this pathologic process. The following is the report of a case that illustrates the utility of MRI in determining the e...
INTRODUCTION Pigmented villonodular synovitis (PVNS) is a proliferative condition of the synovium, which is composed of nodules and/or villi and has an abundant number of hemosiderin-laden macrophages. CASE REPORT A 10-year-old boy presented with an acute irritable knee. Emergency arthroscopy showed a nodular PVNS in the intercondylar notch. The symptoms resolved after resection of the lesion...
Pigmented villonodular synovitis (PVNS) is a proliferative benign lesion originating from the synovium and commonly affects large joints of the extremities. PVNS can arise from any synovium in the whole body and rarely affects the zygapophyseal joints of the spine. Spinal PVNS is diagnosed mostly after resection of the mass. In our case we present a 22-year-old male patient showing progressive ...
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 pathol...
Introduction: Pigmented villonodular synovitis (PVNS) after replacement arthroplasty is a potential cause of postoperative pain and hemarthrosis. The disease is difficult to diagnose after arthroplasty, since magnetic resonance imaging (MRI) appearances are subject to metal artifact making them less than ideal. Case Report: A case of a 61yearold woman with PVNS after unicompartmental knee art...
Pigmented villonodular synovitis (PVNS) is a rare disease. It is a benign neoplastic process typically affecting young to middle-aged adults and most commonly involving the knee, hip, and shoulder joints. The symptoms include diffuse pain and swelling with discomfort. We report a rare case of localized PVNS originating at the proximal tibiofibular joint in a 39-year-old female patient with radi...
Pigmented villonodular synovitis (PVNS) is a benign proliferative disorder primarily occurring in the large joints of the appendicular skeleton such as the knee and hip joints. We present an unusual case of PVNS involving the cervical spine in an adult. MR imaging showed an enhancing mass lesion arising from the posterior elements of the cervical spine and hyperintensity on the T2-weighted imag...
