Thymomas are rare epithelial tumors of the mediastinum with relatively good prognosis compared to other thoracic malignancies. Surgery is considered the best treatment and the most important determinant of long-term survival even in advanced stages. Nevertheless, complete resection may be challenging and require a multimodality approach. We present a case of a stage IVa thymoma surgically treated. The superior vena cava was completely occluded and, after resection, reconstruction was deemed unnecessary due to sufficient venous return through the azygos-inferior vena cava system. In our opinion, despite the morbidity of surgery in advanced thymomas, it should always be considered in expert hands.
