Figure 12 (A-H): Axial CT scan (A and B) reveal heterogeneously enhancing soft tissue in posterior ethmoid sinuses with extension into both orbits (black arrow). The soft tissue appears marked T2 hypointense (C) and T1 isointense with few hyperintense foci (D). Orbital and extradural anterior cranial fossa spread (thin white arrow) is seen on coronal T2 (E) and postcontrast T1 (F) images. Extension in right cavernous sinus (thick white arrow) is seen (G) with resultant right ICA territory infarcts (curved arrow in H)
