Abdominal neuroblastoma in a child with inferior vena cava anomaly.

Congenital anomalies of the inferior vena cava are rare. Such anomalies pose great challenges to the surgeon in neuroblastoma surgery, especially when unrecognised preoperatively. We report the first case of an abdominal neuroblastoma detected in a child with a developmental anomaly of the left-sided inferior vena cava. The patient underwent surgical resection after good response to preoperative chemotherapy.
