An unusual case of leiomyosarcoma of the inferior vena cava in a patient with a duplicated inferior vena cava.
Leiomyosarcoma of primary vascular origin is a rare primary soft tissue tumour, which arises mainly from the inferior vena cava (IVC). Clinical symptoms depend upon the size and location of the tumour and presents usually with abdominal pain, palpable mass and weight loss. Complete surgical resection with clear surgical margin plays a central therapeutic role. The effect of chemotherapy and radiation therapy remains to be evaluated. We report a 64 year old Chinese female who presented with abdominal mass and pain associated with weight loss and was subsequently diagnosed with inferior vena cava leiomyosarcoma. She underwent successful surgical resection but unfortunately developed recurrence of tumour 12 month post-operative. She was also found to have a duplicated inferior vena cave which allowed reconstitution of venous return from the lower limbs after surgical resection of the IVC tumour. We discuss the surgical treatment and results of leiomyosarcoma of the IVC.
