Brief summary

Inferior vena cava (IVC) is the largest vein is the body, draining blood from the abdomen, pelvis and lower extremities. IVC anomalies can be congenital or acquired. The origins of these anomalies are not entirely clear, and their incidence is uncertain. Imaging plays a pivotal role in diagnosis to prevent misinterpretation. CT scan is a quick, available, and suitable imaging modality in emergency setting. The aim of this retrospective monocentric study was of describe CT features of interrupted suprarenal inferior vena cava with azygous continuation.
