A–F coronal sections through the pathological vertebral intercentrum (anterior towards posterior, right side towards the left side of the page) with star-shaped structure (red dotted line); G, H 3D volumetric reconstruction of the remaining normal part of the pathologically-altered intercentrum in (G) anterior and (H) posterior view exhibiting a subconical shape with star-like process visible in its anterior part and more oblate in the posterior part; I, J 3D reconstruction of the outgrowth in (I) anterior and (J) posterior view. The planes of virtual sectioning are presented in Additional file 5. The physical cutting planes of the specimen are consistent with the virtual sectioning shown in Additional file 5
