To review and describe clinical, pathological and radiological findings of aortitis showing representative cases of the most frequent conditions. To stand out the important role of cross sectional imaging (TC, PET/TC and MRI) in the management and follow-up of these patients.

Aortitis is a subtipe of vasculitis that involves histologically inflammation of the aortic wall. This is a specific condition of the wide spectrum of vasculitis that show different etiologies, pathophysiologies, clinical manifestations and prognoses. Aortic wall inflammation may be caused by an infectious etiology but it is more often due to a non-infectious origin. Theres is a broad classification of aortitis and different clinical conditions associated as it is shown in table 1 (Fig.1). Clinical manifestations depend on the etiology of vasculitis but are often...

We revised in our hospital files all aortic aneurysms that had been operated in our center in the last 5 years. In total 323 cases were found and only 19 of them had histological proven diagnosis of aortitis: 5 IgG4-Related Disease Aortitis, 5 Takaysus artertitis, 1 Giant Cell arteritis, 2 piogenic aortitis, 4 micotic aneurysms and 2 chronic periaortitis. Aortitis can be broadly classified as infectious or non-infectious due to practical clinical purposes as this two entities involve different inmmediate therapeutic consequences. It is important...

CONCLUSIONS Aortitis is a complex disease caused by different etiologies. It is frequently misdiagnosed as patients manifest scarce clinical symptoms but its diagnosis is crucial as sometimes consequences can be fatal if left untreated. Differentiating non-infectious from infectious aortitis constitutes the first approach. It is important to make the distinction between these two entities as clinical management, treatment and outcome differ. Although aortitis is an infrequent entity, radiologists play an important role as a multimodality imaging approach is needed for diagnosis and follow up.
