The Mystery of the Swollen Knee - Abstract
We described a case of a 59-year-old male with fevers, right knee swelling, noninflammatory synovial fluid with negative gram stain and without crystals. Ultrasound examination of the periarticular structures of the knee demonstrated intra-tendinous patellar tendon tophaceous deposits and associated deep-infrapatellar gout bursitis. This case highlights the use of bedside ultrasound in the real-time diagnosis of patients with monoarticular inflammatory arthritis, direct quantification of the extent of crystal deposition disease, accurate assessment of inflammatory involvement of joints, bursae, tendons and soft tissues becoming a distinctive imaging modality for evaluation of crystal arthropathies.
