title: [Knee pain--localized pigmented villonodular synovitis].
abstract: A case of extraarticular localised pigmented villonodular synovitis (LPVS) in the knee is described. LPVS was misinterpreted clinically and with magnetic resonance imaging as infrapatellar bursitis. Treatment was with partial arthroscopic synovectomy and total excision. The diagnosis was verified histologically.
