Agenesis of the Intrahepatic Inferior Vena Cava: A Case Report and Literature Review.

Anomalies of the inferior vena cava (IVC) are an uncommon finding in the general population. A wide range of IVC anomalies has been described in the literature, the majority of which lack clinical significance. Agenesis of the IVC (AIVC) is a rare anomaly of the IVC in the general population.This anomaly may involve either complete agenesis of the IVC or agenesis of a segment of the IVC. Agenesis of the suprarenal segment is the most commonly occurring variant, while agenesis of the infrarenal and hepatic segments is less common. Here we report a case of agenesis of the intrahepatic segment of the IVC.
