ABSTRACT
INTRODUCTION: pigmented villonodular synovitis (PVNS) is a benign condition that affects the knee, leading to abnormal proliferation of the synovial membrane and the accumulation of hemosiderin in the joint cavity. Although it can be surgically treated, PVNS tends to have a high recurrence rate, potentially resulting in chronic joint damage. CASE REPORT: we present the case of a young woman who experienced localized pain in her right knee due to a recurrence of PVNS. Magnetic resonance imaging revealed multiple multilobulated cystic lesions affecting the entire joint, including the ligaments. The patient underwent open surgical resection with a favorable clinical outcome. Histopathological examinations confirmed the absence of malignancy. CONCLUSION: while arthroscopy is typically the preferred treatment for PVNS, this case highlights the tendency for recurrence associated with this approach. Open surgical resection, supported by benign histopathological findings in this case, suggests a favorable long-term prognosis.
INTRODUCCIÓN: la sinovitis villonodular pigmentada (SVNP) es una enfermedad benigna que afecta la articulación de la rodilla, que causa una proliferación anormal de la membrana sinovial y la acumulación de hemosiderina en la cavidad articular. A pesar de que es posible tratarla mediante cirugía, la SVNP tiende a tener una alta tasa de recurrencia, lo que puede resultar en daño articular crónico. REPORTE DEL CASO: se presenta el caso de una mujer joven que experimentó dolor localizado en la rodilla derecha debido a una recurrencia de SVNP. La resonancia magnética reveló múltiples lesiones quísticas multilobuladas que afectaban a toda la articulación, incluyendo los ligamentos. La paciente fue sometida a una resección quirúrgica abierta, con una evolución clínica favorable. Los exámenes histopatológicos confirmaron la ausencia de malignidad. CONCLUSIÓN: aunque la artroscopía se considera el tratamiento de elección para la SVNP, este caso ilustra la tendencia a la recurrencia asociada con este enfoque. La resección quirúrgica abierta, respaldada por los hallazgos histopatológicos benignos en este caso, sugiere un pronóstico favorable a largo plazo.

Introducción: la sinovitis vellonodular pigmentada es una proliferación sinovial benigna, asociada a depósitos de hemosiderina, originada en las articulaciones, bursas o vainas tendinosas. La articulación más afectada es la rodilla, seguida de la cadera y, menos frecuentemente, hombros, codos y tobillos. Las características imagenológicas de esta afección son muy particulares, lo que permite una buena aproximación diagnóstica mediante los diferentes métodos radiológicos, en particular la resonancia magnética nuclear. Objetivo: presentar un paciente enfermo de sinovitis vellonodular pigmentada, en cuyo diagnóstico los métodos imagenológicos fueron cruciales, particularmente la resonancia magnética nuclear.Presentación del caso: paciente masculino de 41 años de edad, con antecedentes de salud. Presentó un cuadro doloroso en la articulación de la rodilla izquierda, de dos años de evolución, con aumento de volumen y agravamiento de los síntomas en los dos últimos meses., La ecografía de rodilla no mostró hallazgos imagenológicos. El diagnóstico se confirmó mediante la resonancia magnética nuclear (con administración de contraste endovenoso) y el estudio histopatológico.Conclusiones: ante un paciente con sospecha diagnóstica de sinovitis vellonodular pigmentada se deben hacer los estudios imagenológicos para buscar los hallazgos típicos de esta enfermedad. Es crucial el empleo de la resonancia magnética nuclear como método de elección, porque permite identificar las características imagenológicas específicas de las lesiones (distinguibles de las correspondientes a otras afecciones sinoviales) y su extensión en las partes blandas(AU)
Introduction: pigmented villonodular synovitis is a benign synovial proliferation, associated with hemosiderin deposits, originating in the joints, bursas or tendon sheaths. The most affected joint is the knee, followed by the hip and, less frequently, shoulders, elbows and ankles. The imaging characteristics of this condition are very particular, which allows a good diagnostic approach through different radiological methods, particularly nuclear magnetic resonance.Objective: to present a patient with pigmented villonodular synovitis, in whose diagnosis imaging methods were crucial, particularly nuclear magnetic resonance.Case presentation: 41-year-old male patient with a health history. He presented a painful picture in the left knee joint, of two years of evolution, with volume increase and worsening of symptoms in the last two months. Ultrasound of the knee showed no imaging findings. The diagnosis was confirmed by nuclear magnetic resonance (with administration of intravenous contrast) and histopathological study.Conclusions: before a patient with a suspected diagnosis of pigmented villonodular synovitis, imaging studies should be done to look for the typical findings of this disease. The use of nuclear magnetic resonance as a method of choice is crucial, because it allows to identify the specific imaging characteristics of the lesions (distinguishable from those corresponding to other synovial conditions) and its extension in soft tissues(AU)

Pigmented villonodular synovitis is a benign tumor of synovial tissue with a very low incidence. Ankle location is even less frequent. Early diagnosis and management are required to avoid irreversible functional and mechanical sequelae. The clinical presentation starts with edema or joint effusion and may progress with pain and advanced joint degenerative changes. Pigmented villonodular synovitis can be focal or diffuse, the latter being the type with the worst prognosis. When suspected, magnetic resonance imaging is performed, and the diagnosis confirmed with a biopsy in which synovial inflammatory tissue with hemosiderin deposits is observed. An open or arthroscopic synovectomy is preferred over surgical management. Recurrence is up to 40%, which is why biological coadjutant therapies and radiotherapy are described. This article presents the case of a 30-year-old man who presented with pain and claudication of the left ankle; the imaging study findings were compatible with diffuse pigmented villonodular synovitis of the ankle with extension to the subtalar joint, leading to arthroscopy for treatment and biopsy. This case report illustrates the results with this patient and a literature review of the subject.
La sinovitis villonodular pigmentada es un tumor benigno del tejido sinovial de muy baja incidencia. El compromiso de tobillo es aún menos frecuente. Se requiere diagnóstico y manejo precoz para evitar secuelas funcionales y mecánicas irreversibles. Se manifiesta inicialmente con aumento de volumen de partes blandas, edema o derrame articular y puede evolucionar con dolor progresivo y daño articular avanzado. Existe una forma focal y una difusa, siendo esta última la de peor pronóstico. El examen diagnóstico de elección es la resonancia magnética, confirmándose por biopsia en la que se observa tejido sinovial inflamatorio con depósitos de hemosiderina. El tratamiento es quirúrgico y consiste en sinovectomía abierta o artroscópica. La recurrencia es de hasta un 40%, por lo que están descritas terapias coadyuvantes biológicas y radioterapia. Este artículo expone el caso de un hombre de 30 años que consulta por dolor y claudicación del tobillo izquierdo, encontrándose en el estudio imagenológico (resonancia magnética) hallazgos compatibles con sinovitis villonodular pigmentada difusa del tobillo, con extensión a la articulación subtalar, por lo que se realiza artroscopía para tratamiento y biopsia. En este reporte de caso se ilustran los resultados con este paciente y una revisión bibliográfica del tema.

Abstract: Introduction: Pigmented villonodular synovitis (PVNS) is a rare clinical entity with higher incidence in women (3:1) and an age of presentation between 20 and 40 years. The hip is a rare site of appearance, being involved in only 15% of all cases. Case report: 47-year-old male with 10 years of evolution characterized by a limited range of motion, pain associated with an increase in volume and shortening of the pelvic limb. Imaging studies showed destruction of the hip joint and extension to the pelvis. The histopathology report described pigmented villonodular synovitis. His final treatment was left hemipelvectomy. Discussion: The presentation of the diffuse pigmented villonodular synovitis of the hip has a lower incidence and a locally aggressive behavior. It is necessary to consider differential diagnoses that include malignant neoplasms. The standard treatment is surgical.

ABSTRACT Pigmented villonodular synovitis is a rare proliferative condition of the synovium. Although the condition can present in any joint, the knee is the most commonly affected site. Despite being a benign condition, pigmented villonodular synovitis is often aggressive, with marked extra-articular extension in some cases. Monoarticular involvement occurs in two forms: localized and diffuse. The latter is more common, with a high recurrence rate. There is no standard method of management of this lesion. Open surgery is a classical and effective method for treatment. Arthroscopic synovectomy, however, has gained popularity, and has several advantages over the open technique particularly in exclusively articular cases. The combined approach is suggested in cases with extra-articular involvement. Synovectomy through any approach may prevent secondary osteoarthritis and subsequent joint arthroplasty. Internal irradiation or external beam radiation as an adjuvant treatment to surgical synovectomy appears to decrease the rate of local recurrence in diffuse cases. The authors observed a great heterogeneity in reporting of functional results, and specific conclusions should not be drawn. Each patient should be managed in accordance with his/her particular condition.
RESUMO A sinovite vilonodular pigmentada é uma rara condição proliferativa da membrana sinovial. Apesar de a doença poder estar presente em qualquer articulação, o joelho é o local mais frequentemente afetado. Ainda que doença benigna, geralmente tem comportamento agressivo, pode ter extensão extra-articular em alguns casos. O acometimento monoarticular ocorre em duas formas: localizada ou difusa. A forma difusa é mais comum e tem alta taxa de recorrência. Não há método padronizado para o manejo dessa lesão. O tratamento cirúrgico aberto é o método clássico e efetivo. A sinovectomia artroscópica, entretanto, tem ganhado popularidade e tem diversas vantagens sobre a técnica aberta, principalmente em casos exclusivamente articulares. A abordagem combinada é sugerida em casos com envolvimento extra-articular. A sinovectomia pode prevenir a osteoartrose secundária e o subsequente tratamento reconstrutivo. A radioterapia usada como tratamento adjuvante à sinovectomia parece diminuir a taxa de recorrência local na forma difusa da doença. Os autores encontraram grande heterogeneidade na forma como os resultados funcionais foram reportados e não se deve chegar a conclusões específicas. Cada paciente deve ser manejado de acordo com suas particularidades.

ABSTRACT 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. The patient presented excellent progress through the physiotherapeutic rehabilitation proposed and continued to be asymptomatic 12 months after the operation.

OBJETIVO: Mostrar los hallazgos imagenológicos en la resonancia magnética (RM) de la sinovitis vellonodular pigmentada (SVP) y el tumor de células gigantes de la vaina sinovial (TCGVS), dado que son entidades que representan un diverso grupo de alteraciones en la proliferación de la sinovial. MATERIALES Y MÉTODOS: Entre mayo de 2011 y junio de 2013, se estudiaron en nuestra institución 25 casos con diagnóstico histológico de proliferación de la sinovial. Se destacaron los distintos tipos de presentación en imágenes a través de una RM 1.5 Tesla. Los resultados fueron analizados y comparados con la literatura. RESULTADOS: La RM mostró características similares para esta patología en todos los pacientes. No obstante, se distinguieron 4 patrones principales de presentación, dependiendo de la morfología, la localización de la lesión y las características radiológicas diferenciales. Estos fueron: como dominante, el tumor de células gigantes de la vaina sinovial (n = 10), todos de localización extraarticular; la sinovitis vellonodular pigmentada de localización bursal (n = 2); la sinovitis vellonodular pigmentada de forma intraarticular focal (n = 5); y la sinovitis vellonodular pigmentada difusa (n = 8). CONCLUSIÓN: La sinovitis vellonodular pigmentada y el tumor de células gigantes de la vaina sinovial se consideran entidades similares desde el punto de vista anatomopatológico. La RM fue de gran utilidad para objetivar tanto las características radiológicas comunes como las diferenciales. Estas últimas, junto con la localización, nos permitieron clasificar 4 patrones de presentación. Su reconocimiento posibilita un adecuado seguimiento de la patología y un óptimo manejo terapéutico.
PURPOSE: To show the resonance magnetic imaging (MRI) findings of pigmented villonodular synovitis (PVNS) and giant cell tumor of the tendon sheath (PVNTS), entities with similar histology but differences in clinical and some radiological manifestations. MATERIALS AND METHODS: We studied 25 cases with histologically benign synovial proliferation in intra and extraarticular location of the extremities. It highlighted with a 1.5T MRI unit the different types of images presentation. The results were analyzed and compared with the literature. RESULTS: MRI displayed very specific imaging features in all patients. However, we were able to distinguish 4 main patterns of presentation depending on the morphology, location of the lesion and radiological differential. These were: as dominant presentation, pigmented villonodular synovitis localized form (n=10); pigmented villonodular synovitis bursal form (n=2); pigmented villonodular synovitis focal (n =5); and pigmented villonodular synovitis diffuse (n = 8). CONCLUSION: Both pigmented villonodular synovitis as well as giant cell tumor of the tendon sheath are considered similar from the point of view of the histological findings. MRI was useful to objectify both radiological features in common, such as the differential, which along with the location, allow us to classify patterns into 4 individual presentations.

Introducción: El objetivo de nuestro trabajo es presentar una serie de 35 pacientes con diagnóstico de quiste articular de rodilla sintomático tratados de forma quirúrgica. Se describe el algoritmo diagnóstico, los resultados y el índice de recidiva. Material y método: Se evaluaron en forma retrospectiva 35 pacientes con diagnóstico de quiste articular de rodilla los cuales fueron tratados en forma quirúrgica. Excluimos aquellos pacientes con diagnóstico de ligamento mucoide y quiste para-meniscal. Veinte hombres, 15 mujeres, con una edad promedio de 39 años. En todos ellos se realizó una biopsia escisión: 31 a través de una artroscopía y 4 resección a cielo abierto. La clínica variaba entre hidrartrosis, bloqueo articular y dolor inespecífico. En todos los casos se realizó el mismo algoritmo diagnostico mediante resonancia magnética (RM). Se realizó un seguimiento clínico para evaluar recidiva. Resultados: El diagnostico se confirmó a través de anatomía patológica en todos los casos, obteniendo 16 sinovitis vellonodular pigmentada focalizada, 5 quiste mucoide, 4 quiste sinovial, 1 quiste de tejido fibroso, 6 gangliones del LCA y 1 del LCP, 2 fibrosis postoperatorios de LCA y 2 quiste de Baker. Treinta y cuatro pacientes evolucionaron en forma favorable. Un paciente con quiste de Baker complicado evolucionó con una recidiva luego de 6 meses de la cirugía. Conclusión: La RM preoperatoria es de gran importancia, ya que los quistes se pueden localizar en zonas de difícil acceso o no exploradas en forma habitual. Es importante la sospecha de este tipo de patología ya que con un diagnóstico temprano y tratamiento quirúrgico se obtienen resultados satisfactorios. Nivel de Evidencia: IV. Tipo de Estudio: Serie de Casos. Retrospectivo.
Introduction: The objective of this study was to investigate a series of 35 patients diagnosed with symptomatic intraarticular knee cysts and describe the diagnostic techniques and surgical treatment. Materials and Methods: This is a retrospective study involving 35 patients diagnosed with intra-articular knee cysts who underwent surgical treatment. We excluded patients diagnosed with a mucoid ligament and para-meniscal cysts. Twenty of the patients were men, 15 women with an average age of 39 years old. All patients underwent an escitional biopsy: 31 using arthroscopy and 4 with an open resection. Among the clinical variations were hydarthrosis, joint lock and complaints of unspecific pain. All of the mentioned cases were diagnosed using MRI imaging and clinical follow up care in order to evaluate suspicion of relapse. Results: The diagnosis was confirmed through anatomic pathology in all cases, with 16 focalized pigmented villonodular synovitis, 5 mucoid cycts, 4 synovial cysts, 1 fibrosis cyst, 6 ACL ganglions, 1 PCL ganglion, 2 ACL post-operative fibrosis and 2 Bakers cycts. 34 patients showed favorable outcome and one patient with a Bakers Cyst presented complication with a relapse 6 months after the inicial surgery. Conclusion: The pre-operative MRI is of great importance, cycts can be found in areas that are difficult to access or located in areas that are rarely explored. It is important to suspect these types of pathologies due to the fact that an early diagnosis and surgical treatment lead to favorable results. Level of Evidence: IV. Study Design: Retrospective.
