De Quervain’s tenosynovitis is a painful inflammatory condition affecting the tendons on the thumb side of the wrist, specifically the abductor pollicis longus and extensor pollicis brevis. In musculoskeletal (MSK) ultrasound, it presents as thickening and fluid accumulation (tenosynovitis) within the first dorsal compartment. This common medical condition often causes pain with gripping or pinching movements.
For medical professionals, ultrasound is a key diagnostic tool for De Quervain’s tenosynovitis, offering real-time visualization of tendon inflammation and swelling. Accurate ultrasound assessment aids in confirming the diagnosis, guiding targeted injections, and monitoring treatment response. Understanding the sonographic appearance is crucial for effective patient management in MSK disorders.
