title: Intra- and infrahepatic agenesis of the inferior vena cava with azygos continuation accompanied by duplication of the postrenal segment.
abstract: Agenesis of one or more segments and duplication of the infrarenal segment are, individually, rare abdominal variants of the inferior vena cava (IVC). In this article, the authors report on a case in which these two anomalies occurred concurrently. Details of the embryology are presented insofar as they are necessary for an understanding of this IVC variant. Spiral computed tomography makes it possible to define the vascular morphology and to make a differentiation from lymphadenopathy. Cavography gives an overall picture of the vascular morphology.
