A chest  computed tomography (CT) scan (Fig. 2)  showed an anterior soft-tissue hypodense  mass on the right with herniation across the  midline to the left hemithorax that displaced  surrounding structures but was not encasing  them.
Anterior sternotomy revealed the well-capsulated mass, which was resected in totality.

The tumour was initially  removed as a well-encapsulated bilobar mass,  but the mass extended posteriorly into the right  thorax and required some piecemeal resection  (Fig. 3).
