There is an anterior mediastinal soft tissue mass that encases both distal brachiocephalic veins and the proximal superior vena cava. This mass heterogeneously enhances with foci of calcifications within. It further invades the lumen of superior vena cava. Thrombus is also noted in the right pulmonary artery. Small thrombi are also found in the most distal veins adjacent to the pericardium.
There are pulmonary metastases.
Presence of arteria lusoria.
CT-guided biopsy confirmed a thymoma.
