A right-sided thoracotomy was performed for pulmonary metastases in an asymptomatic patient. Preoperative computed tomography (CT) scan showed partial thrombosis or agenesis of the inferior vena cava (Fig. 1). Intra-operatively, an impressive dilation of the azygos vein was noted (Fig. 2). The azygos vein or superior vena cava was not invaded by tumour.
