Fig. 2.

Contrast enhanced axial (top and bottom left), sagittal (right), and coronal (middle) CT images demonstrates heterogenous upper mediastinal mass with internal calcifications (red arrows) that measured approximately 7.5 × 7.4 × 7.6 cm interposed between and splaying the great vessels (yellow arrows). This lesion extends superiorly and inferiorly causing severe left to right mass effect and compression on the trachea (blue arrows). There is abutment of the lesion on the cervicothoracic spine (green arrow). (Color version of figure is available online.)
