title: Arthrographic demonstration of pigmented villonodular synovitis of the knee.
abstract: Arthrography of the knee is most frequently used for diagnosis of conditions affecting the cartilage and menisci. In a 40-year-old man with pigmented villonodular synovitis, arthrography demonstrated a characteristic pattern of multiple filling defects. Arthrography may prove to be as useful for diagnosis of synovial lesions as for other intraarticular lesions.
