Abstract

Ultrasonography (US) is a cost effective diagnostic imaging tool suitable for routine clinical use. High frequency US is a well-established method for both the diagnosis and monitoring of inflammatory arthritis, capable of detecting a wide range of joint pathologies, including effusion, synovitis, and extra-articular abnormalities. However, to ensure an accurate diagnosis, it is also important to consider periarticular disorders that could clinically mimic joint pathology. Such a diagnosis requires special attention to be paid to the periarticular structures, include the tendon, ligament, muscle, and bursa. Due to the close proximity of these structures to potentially affected joints, periarticular inflammation is often clinically misdiagnosed as articular in origin. In these cases, the processes driving pathology are the result of localized inflammation that is secondary to inflammatory arthritis, such as excessive friction or direct trauma. Therefore, when using US to diagnose inflammatory arthritis, it is important to understand the causative pathology of the periarticular disorders, as well as their clinical presentation.
