Figure 1.
Krapina 120.71 in a caudal view (a).
The large lesion is located above the tubercular facet and extends laterally. The trabeculae have been destroyed and the cortex appears expansive. The thin cortical bone forming the superior surface of the cavern was broken away postmortem. (b) Krapina 120.6 shows the normal pattern of bony trabeculae in the medullary space. The surface irregularities are post-mortem.

Two views of Krapina 120.71 rib fragment: a: Superior/inferior radiograph view of Krapina 120.71 in position matching illustration in Figure 1; b: Lateral view in position matching the µ-CT scan series in Figure 3. The radiograph shows the full extent of the bony cavern excavated by the growth of the dysplastic mass. The lesion occupies most of the length of the fragment, but does not extend beyond the medial and distal borders. The full extent of the lesion is visible within this small rib fragment.
Figure 3.
Krapina 120.71 was µ-CT scanned at 20 micron intervals (voxel size, 20 microns) across the long axis of the curved bone producing 495 individual images.
Four slices are illustrated here showing the changing architectural detail of the internal tumor compartment. Loculations and vertical septations are clearly visible on each slice. Radiodense particles represent areas of adhering soil matrix that were part of the sedimentary environment.
