Aortopathy is a term most commonly used to describe a group of genetic diseases that predispose patients to an elevated risk of aortic events including aneurysm and acute aortic syndrome. Types of genetic aortopathy are classified as either heritable or congenital, with heritable thoracic aortic disease (HTAD) further subclassified into syndromic HTAD or nonsyndromic HTAD, the former of which is associated with specific phenotypic features. Radiologists may be the first physicians to encounter features of genetic aortopathy, either incidentally or at the time of an acute aortic event. Identifying patients with genetic aortopathy is of substantial importance to clinicians who manage thoracic aortic disease, because aortic diam-eter thresholds for surgical intervention are often lower than those for nongenetic aortopathy related to aging and hypertension. In ad-dition, when reparative surgery is performed, the approach and ex-tent of the repair may differ in patients with genetic aortopathy. The radiologist should also be familiar with competing diagnoses that can result in acute aortic events, mainly acquired inflammatory and noninflammatory thoracic aortic disease, because these conditions may be associated with increased risks of similar pathologic end-points. Because many imaging and phenotypic features of various types of genetic aortopathy overlap, diagnosis and determination of appropriate follow-up recommendations can be challenging. A multidisciplinary approach with the use of imaging is often required and, once the diagnosis is made, imaging has additional importance because of the need for lifelong follow-up.
