Abstract

Since three dimensional and reformatted CT images can show changes in the location and size of the azygos system, changes in the surrounding vessels, and combined anomalies of vessels or organs, CT is useful for diagnosing congenital and acquired abnormalities of the azygos system. In this article, we review CT findings in regards to various disorders involving the azygos system.

Keywords: Azygos Vein, CT, Congenital Anomaly, Abnormalities
