Abstract:

 

Pigmented villonodular synovitis is a rare monarticular proliferative disorder of the synovium, most commonly affecting the knee. There are very few reports about the localized form in the knee. A twenty-eight-year-old woman presented with complaints of pain, catching, and locking. The lesion closely resembled a loose body in the medial gutter of the knee. Magnetic resonance imaging was performed to establish the diagnosis. Arthroscopy of the knee was performed and a mass with an attachment to the medial capsule was detected. The mass was removed from the synovium by arthrotomy. Histological examination confirmed the diagnosis. During a-year follow-up, the patient remained asymptomatic. Localized pigmented villonodular synovitis may mimic other intraarticular pathologies and lead to a false diagnosis.
Key words: Arthroscopy; diagnosis, differential; knee injuries/ diagnosis; joint loose bodies/diagnosis; synovial membrane/ surgery; synovitis, pigmented villonodular/diagnosis/surgery.

 

Pigmente villonodüler sinovit, tek eklem tutulumu ile seyreden, nadir görülen, sıklıkla dizi tutan proliferatif bir süreçtir. Lokalize formu bildiren çalışmalar sınırlı sayıdadır. Bu yazıda, 28 yaşındaki kadın hastada, diz iç eklem aralığındaki serbest cismi taklit eden, ağrı, kilitlenme ve takılma gibi yakınmalara yol açan lokalize pigmente villonodüler sinoviti sunuldu. Ayırıcı tanıda manyetik rezonans görüntülemeden yararlanıldı. Yapılan artroskopide, iç eklem aralığında kapsüle yapışık kitle saptandı. Sinovyadan artrotomiyle çıkarılan kitlenin pigmente villonodüler sinovit olduğu patolojik inceleme ile doğrulandı. Hastanın bir yıllık takibinde nüks ile karşılaşılmadı. Lokalize pigmente villonodüler sinovit başka diz içi patolojileri taklit edip yanlış tanıya yol açabilir.
