Persistent Left Superior Vena Cava: A Case Report and Review of the Literature

The persistence of the left superior vena cava (LSVC) is a rare and benign congenital malformation. It is often asymptomatic, and its discovery is usually incidental in the majority of cases. This venous malformation was identified incidentally in a 60-year-old woman during thoracic multi-detector computed tomography (MDCT), which was performed with the suspicion of intra-thoracic malignancy. This is associated with abnormal venous return and an atrial septal communication.
