Abnormal ultrasound findings in rheumatological diseases (definitions)

The OMERACT ultrasound group published a consensus in 2005 of widely accepted definitions of abnormal ultrasound findings in rheumatological diseases:

  • erosion: an intra-articular discontinuity of the bone surface that is visible in two orthogonal planes
  • joint effusion: abnormal hypoechoic or an anechoic (relative to subdermal fat, but sometimes isoechoic or hyperechoic) intra-articular material that is displaceable and compressible, but does not exhibit Doppler signal
  • synovitis: abnormal hypoechoic (relative to subdermal fat, but sometimes isoechoic or hyperechoic) intra-articular tissue that is non displaceable, poorly compressible, and may exhibit Doppler signal
  • tenosynovitis: abnormal anechoic and/or hypoechoic (relative to tendon fibers) tendon sheath widening or distention, which can be related to the presence of both abnormal tenosynovial fluid and/or synovial hypertrophy
  • enthesitis: entheseal thickening, hypoechogenicity, and the presence of Doppler signal as a marker of active inflammation
