Figure. 1: A large, irregular, swelling involving Upper 2/3 of sternum extending to suprasternal notch (blue arrow) and right shoulder.
Figure 2: Computed tomography (CT) of the thorax in axial (A) (B) and coronal (C) and Sagittal (D) plane, showing large exophytic bony mass (black Asterisk) arising from the right side of the chest wall. The mass is causing compression over the airway resulting in severe narrowing of the trachea (minimal diameter of 3.4 mm) (white arrow). Multiple other bony exostoses arising from ribs (dashed arrow).
Figure 3: Volume rendered (VR) 3D images of the chest in coronal (A) and oblique plane (B), showing large bony mass (Asterisk) arising from the right side of the chest wall causing significant deformity. Multiple other bony exostoses arising from Ribs and scapula (white arrow). Postoperative 3D VR images of the chest in coronal (C) and oblique plane (D) showing a significant reduction in the size of the bony mass.
