Axial 3DCT scan of the skull base showed osteolytic destruction of the most skull base bony elements, namely, the squamous part of the temporal bones associated with lysis of the zygomatic arch bilaterally (small arrows). S is the sphenoid bone and C is the occipital part of the clivus (both manifested osteolytic destruction associated with significant irregularities). In addition the destruction involved the greater wings of the sphenoid bone (fragmentations and massive irregularities were present).
