Idiopathic Azygos Vein Aneurysm Mimicking a Mediastinal Mass: Case Report and Review of Literature

Abstract

True aneurysmal dilatation of the azygos vein is a rare entity which has been reported in literature on only a few occasions. We report a case of idiopathic azygos aneurysmal dilation that was incidentally discovered on chest roentgenogram as a mediastinal mass. A contrast enhanced CT scan of the chest showed a large azygous arch aneurysm with normal appearance of other mediastinal vasculature. She was managed conservatively with outpatient follow up. A repeat CT Chest after one year showed no change in size of the aneurysm.
