Interrupted inferior vena cava (IVC) is a rare developmental defect. IVC interruption is usually accompanied with azygos and hemiazygos continuation, and is asymptomatic. Here, we report the imaging findings of a patient with an interrupted IVC with diffuse collaterals between the infrarenal IVC and large renal veins, left gonadal, and perirectal haemorrhoidal-portal collateral veins with associated haematochezia. Depending on the haemodynamic changes, interrupted IVC may cause possible different clinical findings as presented here.
下腔静脉中断是一种罕见的发育缺陷。下腔静脉中断通常伴有奇静脉和半奇静脉延续，且无症状。在此，我们报告一例下腔静脉中断患者的影像学表现，其肾下下腔静脉与大肾静脉、左性腺静脉及直肠周围痔门静脉侧支之间存在弥漫性侧支循环，并伴有便血。根据血流动力学变化，下腔静脉中断可能会导致如本文所述的不同临床症状。
