The azygos continuation is a rare variation of the inferior vena cava (IVC), usually associated with cardiac anomalies. We report CT in two female patients with no cardiac disease. One had no further visceral abnormalities, while the other had polysplenia agenesis of the left lobe and a hypertrophic right lobe of the liver. This complex of anomalies has been demonstrated for the first time by imaging. Our cases show the variation of anomalies associated with azygos continuation. When planning therapeutic procedures (for example cava filtration) these anomalies are relevant. CT is sufficient for their demonstration and in most cases there is no need for confirmation by invasive methods.
奇静脉延续是下腔静脉（IVC）的一种罕见变异，通常与心脏异常有关。我们报告了两名无心脏病的女性患者的CT情况。其中一名患者没有其他内脏异常，而另一名患者存在左叶多脾缺如和肝脏右叶肥大。这种异常组合首次通过影像学得到证实。我们的病例显示了与奇静脉延续相关的异常变异。在规划治疗程序（例如腔静脉滤过）时，这些异常情况很重要。CT足以显示这些异常，在大多数情况下无需通过侵入性方法进行确认。
