Fig. 2.

Multicolor 3-dimensional printed model (A and B) visualizing the thoracic spine (white), part of the excluded aneurysm sack (red) and stent graft (blue). The focal protrusion and erosion into the spine are clearly visible (yellow arrow). Cinematic rendering (C-E) of the aneurysm. In C the aneurysm sack (red) is shown as translucent. The focal protrusion and erosion into the spine is shown similarly to the 3D-printed model (A and B). In D the cinematic rendered volume of C is cut in a coronal plane revealing more detailed how the aneurysm sack erodes into the vertebral bodies (red arrows). Cinematic rendering of the high-density structures in E further points out the osseous defects (black arrows).
