Aortitis: Radiological findings in relation to its various etiologies

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.
