title: A natural history of aortic aneurysm hygroma.
abstract: A 56-year-old man with a family history of aortic aneurysm underwent routine repair in 2003. A postoperative computed tomography scan showed a 6-cm perigraft hygroma. Sudden onset of abdominal pain 12 months later revealed a larger hygroma, with an additional anterior fluid collection suggestive of contained rupture. The bilobed hygroma remained stable until 2010, when he presented with chills and severe abdominal pain. A computed tomography scan demonstrated free rupture of the sister hygroma, with air pockets observed within the sac. Conservative management was elected. Air pockets as well as the hygroma eventually resolved, and the patient remains well.
