title: Post-traumatic synovitis presenting as a mass in the suprapatellar bursa of the knee. MRI appearance.
abstract: A lobulated mass in the suprapatellar bursa of the knee is presented with MRI findings simulating the features of focal pigmented villonodular synovitis (PVS). Microscopic examination demonstrated a nonspecific, inflammatory mass of hypertrophied synovium. The MRI features of various forms of synovitis are reviewed from recent literature and differential considerations of a suprapatellar, intrabursal mass are discussed.
