ABSTRACT We report two cases of interrupted inferior vena cava with azygous continuation diagnosed as an isolated finding during routine prenatal scans. Visualization of the venous vasculature of the abdomen and thorax in the mid-sagittal plane failed to visualize the segment of the inferior vena cava between the kidneys and the liver. A vessel with venous flow was observed parallel, adjacent and posterior to the aorta between the kidney and the right atrium. This blood vessel connected with the superior vena cava. Axial planes of the thorax confirmed the presence of two vessels running paravertebrally. A detailed ultrasound examination of the fetal anatomy failed to demonstrate other anomalies. The neonatal course of both fetuses was uneventful. Isolated interruption of the inferior uena cava can be a vascular malformation without known pathological consequences.
