Imaging spectrum of pigmented villonodular synovitis: A case series

Pigmented villonodular synovitis is abenign proliferative disease affecting the synovialjoints resulting in villous or nodular changes inthe synovial tissue, large effusions and bonyerosions.PVNS affects young adults in theirthird or fourth decades with an incidence of 1.8per 1 million per year.Pigmented villonodular synovitis (PVNS) is a slowgrowinglesion of uncertain etiology arising from thesynovial membrane. It is characterized by villous andnodular overgrowths of the synovial membrane of thebursa or the tendon sheath. The appendicular skeleton,especially large joints such as the knee and hipjoints are frequently involved.Here, we highlight the spectrum of findings in histopathological proven cases of PVNS, in particular the varied signal intensity characteristics of PVNS at MR imaging.
