case_images: 3D surgical planning of the cutting guides with the groove (black arrow) for the blade of the bone scalpel and the holes for the fixation screws (black arrowhead) (A). 3D surgical planning with the skull prosthesis in place to fit exactly the craniotomy line (B). 3D printing of the PEEK implant (C). Multilobular osteochondrosarcoma (MLO) intraoperatively with a bilobed shape (black asterisks) (D). MLO stripped of its masses to allow for placement of the cutting guides with craniotomy grove (black arrow) and the fixation screws (black arrowhead) (E). 3D-printed PEEK skull implant after craniectomy and attached to the skull with screws and plates (F). Cr, cranial; Cd, caudal; L, left.

case_images: In order to secure the guide to the skull, holes for fixation screws were added in the design (Figures 1A,E). AG, Essen, Germany), the printer fabricated the cranial implant, with the sliced G-code file subsequently transferred to the printer (Figure 1C). After printing the cranial implant, the raft and support structures were manually removed using rotary tools, with no additional post-processing steps. Figure 1 shows the pre-and post-surgery planning with the cutting guides and prosthesis.
case_images: Computed Tomography [CT; transverse (A,D), sagittal (B,E), dorsal (C,F) views] at the time of diagnosis (A-C) and after placement of the prosthesis (D-F). No dorsal sagittal sinus was visible at the level of the MLO on post contrast CT and MRI.
