Although we often encounter patients with an aortic aneurysm
who also have diffuse idiopathic skeletal hyperostosis (DISH), there
are no reports to date of an association between these two conditions
and the pathogenesis of DISH remains unknown. This study therefore
evaluated the prevalence of DISH in patients with a thoracic aortic
aneurysm (AA). The medical records of 298 patients who underwent CT scans for
a diagnosis of an AA or following high-energy trauma were retrospectively
examined. A total of 204 patients underwent surgery for an AA and
94 had a high-energy injury and formed the non-AA group. The prevalence
of DISH was assessed on CT scans of the chest and abdomen and the
relationship between DISH and AA by comparison between the AA and
non-AA groups.Aims
