title: [Congenital absence of inferior vena cava associated to polispleenism. Case report].
abstract: Interruption of the inferior vena cava with azygos continuation is an uncommon vascular anomaly that results from aberrant development during embryogenesis. We report a case of this anomaly in a young boy of 19 years old sent for our observation for presenting an hipotransparency in the chest x-ray, which study revealed a prominence of the azygos cross. Further evaluation by CT-scans disclosed the diagnosis of congenital absence of the inferior vena cava, associated to multiple spleens (polispleenism).
