Pigmented villonodular synovitis of shoulder; radiologic assessment with MRI findings

Pigmente villonodüler sinovit sinovyumun birikim bozukluğu olup, eklem-tendon ve bursaları sınırlayan dokularda hemosiderin birikimi ile karakterizedir. PVNS sonrasında diffüz ve lokalize formlar olarak sınıflandırılmıştır, en çok etkilenen eklemler diz-kalça ve parmaklardır. Omuz tutulumu oldukça nadirdir. Bu çalışmada, 45 yaşında erkek hastanın sağ omzunda görülen diffüz villonodüler sinovit olgusu sunulmuştur. Tanı patognomonik MR görüntüleme bulguları ve lezyonların histopatolojik analizi ile konmuştur. Buradaki eklem tutulumu monoartiküler tiptedir.

Omuzda pigmente villonodüler sinovit; MR görüntüleme bulgulari ile radyolojik analiz

Pigmented villonoduler synovitis is a proliferative disorder of the synovium and deposition of hemosiderin into the lining tissues of joints, tendons and bursae. PVNS is further classified into diffuse and localized forms, the most affected joints are the knees, hips and fingers. Shoulder involvement is extremely rare. In this paper, we present diffuse villonoduler synovitis of the right shoulder of a 45 year old male. The diagnosis is made by pathognomonic MRI findings and histopathological analysis of the lesions. The joint involvement in this case is of monoarticular type.
