The value of ultrasonography in interrupted inferior vena cava with azygos continuation.

The cardiosplenic syndromes represent a complex set of abnormalities of the thorax and viscera resulting from abnormal folding of the embryo during early development. Anomalies of venous development include interruption of inferior vena cava (IVC), and in combination with situs inversus referred to as the polysplenia syndrome. We present a 23-year-old male previously diagnosed as having a persistent left IVC on venography whereas ultrasonographic examination clearly demonstrated interrupted IVC with azygos continuation along with situs inversus.
