This AFIP radiologic-pathology correlation review covers the full spectrum of PVNS — diffuse intraarticular, localized intraarticular, bursal (PVNB), and tendon sheath (PVNTS/GCTTS) forms — describing their clinical features, pathologic characteristics, imaging findings across all modalities, treatment options, and prognosis including malignant transformation.
When you see diffuse synovial thickening with low T2 signal and hemosiderin blooming on gradient-echo MRI in a monoarticular effusion — especially in the knee or hip of a patient in their 30s–40s.
Think PVNS; get MRI to define full extent (including bursal decompression) before surgery, because incomplete synovectomy drives recurrence rates above 50%. In the hip, expect bone erosion on both sides of the joint in over 90% of cases even when the joint space is preserved.
