RESUMO
Takayasu arteritis (TA) is a chronic inflammatory process of unknown etiology which affects the aorta and its main branches causing occlusion, stenosis or dilation of the vessels concerned. A case of TA in a young woman is presented, who underwent colour doppler duplex ultrasound image study and whose diagnosis was confirmed by magnetic nuclear angioresonance (MNAR). The role of these two explorations in the detection and follow-up of this condition is discussed. Due to the fact that the expression and age at presentation may vary according to the different geographical areas affected, we would especially underline the new diagnostic criteria for this entity and based on the angiography findings obtained.

La arteritis de Takayasu (AT) es un proceso inflamatorio crónico de etiología desconocida que afecta a la aorta y sus ramas principales, lo que provoca oclusiones, estenosis o dilataciones en los vasos afectados. Presentamos un caso de AT en una mujer joven estudiada por ecodoppler duplex color y confirmada por angiorresonancia magnética nuclear (ARMN). Discutimos el papel de estas dos exploraciones en la detección y el seguimiento de la enfermedad. Debido a que su expresión y edad de presentación puede variar según las diferentes áreas geográficas afectadas, hacemos especial hincapié en los nuevos criterios diagnósticos para esta entidad, basados en los hallazgos angiográficos obtenidos (AU)

At presentation the history of a 51 years old woman with xerostomia and dry keratoconjunctivitis sicca (KCS) with a development of ten months. Investigations revealed the presence in serum of antibodies against cytoplasmic antigens SS-A (Ac anti-Ro/SS-A), antinuclear antibodies (ANAS), and rheumatoid factor (RF). The test with Rose of Bengal was positive, and in the salivary gammagraphy made with pertecnate-99 m Tc it was observed a decreased of the captation and excretion of the designer for the salivary glands. The histopathology and immunohistochemical study of the minor salivary glands showed the presence of a focal lymphocytic sialadenitis (fls) and a predominance of lymphocytes CD4+. It was diagnosed a primary Sjögren a Syndrome (SSP) and the patient was treated with salivary substitutes and artificial tears. We analyse the current diagnostic criteria of the group of studies of the European Community for the SS. We emphasize the importance of the histologics and immunohistochemical study that with the rest of the complementary test will let us to distinguish not only the different forms of presentation of the illness, but also those of all the patients with pathologies which are very prevalent in our environment nowadays, such as the infections by virus C of the hepatitis (VCH) and the human immunodeficiency (VIH).
