ABSTRACT

INTRODUCTION/AIM: Rheumatoid Arthritis (RA) an autoimmune, chronic, and disabling disease if untreated, affects wrist joints, with a diagnostic delay of up to 2 years. Triquetral bone allows rotational movement that pivots over the rest wrist bones, and maintains physiological loads during mobility. Magnetic Resonance Imaging (MRI) is the most sensitive (96%) method for diagnosis, evidencing lesions as early as in the initial RA stages. Our aim was to determine the most frequently affected structures in the hand-wrist joint by MRI using the OMERACT-RAMRIS Score (2003) in three different RA stages, including clinically suspicious arthralgia (CSA) that haven't reported before. METHODS: We performed an exploratory, transverse, observational, descriptive study in 60 patients enrolled and classified by rheumatologists as: CSA, early rheumatoid arthritis (ERA), and established RA, prior to performing a dominant hand-wrist MRI for evaluation and descriptive analysis by an expert radiologist. RESULTS: Female predominance 83% (50), with a mean age 42+13.5 years; A total of 1,731 hand-wrist bone and joint sites were evaluated using EULAR-OMERACT Atlas (2005), identifying 56% (964 sites) with typical RA lesions: synovitis, erosions, and bone marrow edema (BME or osteitis); synovitis was the most frequent with 46% (445 site-lesion), and triquetral synovitis the most frequent each clinical group: CSA 87% (20/23), ERA 91% (20/22), and RA 93% (14/15). CONCLUSION: Synovitis and triquetral synovitis were the most prevalent lesion in three-studied phases. This could suggest the triquetrum as the first morphological site to be affected by RA; so it's assessment should be considered in the RA evaluation when it´s clinically suspected.

ABSTRACT

El 6 de mayo de 1998 acudió al servicio de radiología e imagen del CMN 20 de Noviembre del ISSSTE, un paciente femenino de 43 años enviada de hospital de referencia de esta ciudad para realización de US Doppler color de vasos del cuello, por presentar masa palpable anexa a los vasos carotídeos derechos, que pulsa, provoca taquicardia, y crisis hipertensivas de dificíl control, no dolorosa, móvil, con crecimiento lento de cinco meses de evolución; desde el rastreo morfológico se identificó masa hipoecoica bien delimitada, en la bifurcación carotídea, de 3.37 x 1.86 cm de diámetros mayores, que captó diferentes señales de color a pesar de bajar las ganancias totales de color a 68 por ciento, indicando con esto su vascularidad interna, el rastreo espectral con Doppler color hizo evidencia la presencia de flujo retrógrado anormal en la bifurcación carotídea y la aceleración de éste en el tercio proximal de la carotídea interna. A continuación se realizó resonancia magnética con angiorresonancia, con base en la imposibilidad para poder practicar en este caso en particular una angiografía digital debido a las variaciones de presiones arteriales y de coagulación que en la paciente se presentaron. El diagnóstico por imagen no invasivo fue de tumor de cuerpo carotídeo
