Aortitis: Hallazgos radiológicos en relación a sus diversas etiologías / Aortitis: Radiological Findings in Relation to its Various Etiologies

Resumen La inflamación de la aorta (aortitis) es una patología poco frecuente, con etiología infecciosa (pseudoaneurisma micótico, sífilis) y no infecciosa (arteritis, aortitis idiopática, espondilitis anquilosante, entre otras) de difícil diagnóstico clínico y variable pronóstico. Por esa razón, la utilización de diversos métodos por imágenes, tales como la tomografía computada multidetector (TCMD), la tomografía computada por emisión de positrones (PET-TC), la resonancia magnética (RM) y ultrasonido (US) facilitan la identificación, seguimiento y tratamiento de esa entidad. El siguiente trabajo tiene como objetivo realizar una revisión y actualización bibliográfica acerca de la aortitis y sus diversas etiologías, ejemplificando con casos de nuestra institución.

Abstract Aortic inflammation (aortitis) is a rare pathology, with infectious (fungal pseudoaneurysm, syphilis) and noninfectious etiology (arteritis, idiopathic aortitis, ankylosing spondylitis, among others), it has a difficult clinical diagnosis and a variable prognosis. The use of various imaging methods such as multidetector computed tomography (MDCT), magnetic resonance imaging (MRI), positron emission tomography-computed tomography (PET-CT) and ultrasound (US) facilitate the identification, monitoring and treatment of this entity. The following paper aims to perform a literature review and update about aortitis and its various etiologies, exemplifying cases of our institution.

Cogan's syndrome - A rare aortitis, difficult to diagnose but with therapeutic potential / Síndrome de Cogan - Uma aortite rara, de diagnóstico difícil, mas com potencial terapêutico

Summary The inflammation of aortic wall, named aortitis, is a rare condition that can be caused by a number of pathologies, mainly inflammatory or infectious in nature. In this context, the occurrence of combined audiovestibular and/or ocular manifestations eventually led to the diagnosis of Cogan's syndrome, making it the rare case, but susceptible to adequate immunosuppressive treatment and satisfactory disease control.

Resumo A inflamação da parede da aorta, denominada aortite, é uma condição clínica rara, que pode ser causada por diversas patologias, principalmente as de fundo inflamatório e/ou infeccioso. Nesse contexto, a ocorrência de sintomas vestibulares e oftalmológicos associados ao quadro remete ao diagnóstico de síndrome de Cogan, tornando o caso raro, mas passível de tratamento imunossupressor adequado e controle satisfatório da doença.

Arteritis de células gigantes: compromiso extenso de la aorta y grandes ramas demostrado por tomografía por emisión de positrones. Caso clínico / Extensive arterial involvement in giant cell arteritis: report of one case

Large vessel vasculitis and particularly Temporal Arteritis are systemic diseases that may affect the aorta and its major branches, mainly involving extra cranial branches of the carotid artery. We report a 72-year-old man presenting with weight loss, fever and malaise. Positron emission computed tomography (PET CT) showed an extensive inflammation of the aorta and its major branches. Temporal artery biopsy confirmed the presence of vasculitis with granulomas. Treatment with a high dose of steroids had an excellent clinical response. This case underscores the utility of PET CT in the assessment of this disease.
