Pigmented Villonodular Synovitis (PVNS) is a destructive non-nepolastic process that typically involves large synovial joints such as the hips and knees. Involvement of smaller synovial joints occurs but involvement of the spine is unusual. An aggressive case involving a synovial facet joint in the cervical spine with bone destruction is demonstrated with plain film, CT, MRI, and histopathogy. Clues to the non-neoplastic nature of the lesion are the involvement of both sides of the joint.
