Rheumatoid arthritis is a chronic inflammatory disease characterized by the development of osseous and cartilaginous damage .
The correct differentiation between a true erosion and other entities — then often called “ pseudoerosions”—is essential to avoid misdiagnosing rheumatoid arthritis and to correctly interpret the progress of the disease .
The aims of this systematic review were as follows : to create a definition and delineation of the term “ pseudoerosion ” , to point out morphological pitfalls in the interpretation of images , and to report on difficulties arising from choosing different imaging modalities .
The role of ultrasonography in early detection and monitoring of shoulder erosions, and disease activity in rheumatoid arthritis patients; comparison with MRI examination.
OBJECTIVES To determine the accuracy of ultrasound in early detection of bone erosions and monitoring disease activity in rheumatoid arthritis ( RA ) patients using magnetic resonance imaging ( MRI ) as a gold st and ard technique . MATERIAL AND METHODS This prospect i ve study was carried out on 50 patients with known RA and 15 healthy controls .  Conventional radiography was st and ardized and performed in two planes . Ultrasound ( US ) and MRI was performed to evaluate the presence of synovitis , tenosynovitis , and bursitis as well as erosions on ultrasound and MRI .  The results in the study group were compared with those obtained in a control group . RESULT In the study group , the most frequent US finding of shoulder joint was Tenosynovitis of the long head of the biceps tendon . Tenosynovitis was observed in the long head of biceps tendon in 20 joints ( 40 % ) . Erosions of the humeroscapular joint were detected by conventional radiography in 15 ( 30 % ) , by US in 41 ( 82 % ) , and by MRI in 46 ( 92 % ) of the shoulders examined , no statistically significant difference is noted between US and MRI in overall detection of erosion ( P = .333 ) . CONCLUSION US is a helpful imaging method and in comparison with MRI in assessing the shoulder joint and , preferably with MRI , are recommended as additional techniques in the initial diagnostic evaluation when radiography yields negative results
