AbstractLoeys-Dietz syndrome is a recently described autosomal dominant disorder with underlying vasculopathy characterized by aortic and other vascular aneurysmal dissection/rupture. A 61-year-old man is reported who died suddenly and unexpectedly and at autopsy was found to have a ruptured abdominal aortic aneurysm. Additional findings included dolichostenomelia, high-arched palate, and pectus excavatum. There was a strong family history of Loeys-Dietz syndrome, although the decedent had never been tested. Death was, therefore, due to a ruptured abdominal aortic aneurysm in a case of probable Loeys-Dietz syndrome. Although Loeys-Dietz syndrome shares common characteristics with Marfan and other connective tissue syndromes, it is a distinct entity with a much more aggressive clinical course. Lethal events may not occur until later adult life; however, the identification of the syndrome and differentiation from other connective tissue disorders at autopsy is important so that genetic investigation of close relatives can be undertaken with prophylactic surgical treatment if necessary.© 2017 American Academy of Forensic Sciences.
