1. Review the imaging features of pigmented villonodular synovitis (PVNS) including localized extraarticular subtypes pigmented villonodular bursitis (PVNB) and pigmented villonodular tenosynovitis (PVNTS). 2. Present entities that mimic PVNS and emphasize differentiating features across imaging modalities. 3. Discuss treatment options for PVNS.

1. Exhibit typical and atypical imaging findings of PVNS, including:     a. Intraarticular localized and diffuse subtypes     b. Extraarticular localized subtypes (PVNB and PVNTS) 2. Reveal common differential diagnosis for PVNS including:     a. Gout, amyloid, hemophilia (low T1 and T2 intraarticular signal) on MRI     b. Chronic hemorrhagic bursitis and gout for PVNB     c. Gout and sarcomas for PVNTS 3. Discuss treatment options including surgery and radiation therapy.

After viewing this exhibit the participant will: 1. Understand typical and atypical imaging findings of all subtypes of PVNS across a spectrum of imaging modalities. 2. Be able to identify characteristic differentiating features of PVNS and those of common differential diagnoses. 3. Understand appropriate steps for the work-up and treatment of PVNS.
