Figure 1

3D representation (coronal plane) illustrating dural extensions from PSD into the intradiploic bone marrow space at skull vertex. The PSD (yellow) directly overlies the CSF within the subarachnoid space (turquoise). An intradiploic vein (V; dark blue) traverses within the skull bone marrow (beige) adjacent to the PSD. It can be noted how the PSD extends into the intradiploic bone marrow space (PSDe). The different colours of CSF and PSD/PSDe reflect different tracer enrichments. Image: Tomas Sakinis, MD.
