Transposition of the inferior vena cava with hemiazygos continuation: A rare case report

Abstract

Hemiazygos continuation of a left-sided inferior vena cava (IVC) is an extremely rare developmental anomaly. We present the case of a male patient in whom this condition was incidentally discovered during a thoraco-abdominopelvic CT scan. With the widespread use of contrast-enhanced computed tomography and magnetic resonance angiography, the detection of congenital IVC anomalies has become more accessible. These anomalies are often found incidentally during imaging performed for other clinical reasons. Awareness of this anomaly is crucial before any surgical or endovascular procedures to avoid potential complications.
