CT
Left temporal lobe rim enhancing, multi-loculated cystic lesion is demonstrated with moderate surrounding white matter hypodensity. Extensively infiltrating lesion is demonstrated in the left skull base, arising from the left side of the nasopharynx and resulting in bony destruction of mainly the sphenoid bone, also just encroaching on the apex of the petrous temporal bone and clivus. The lesion abuts the left carotid canal. The left sphenoid sinus and ethmoid sinuses are partially opacified. The right sphenoid sinus and left maxillary sinus are almost completely opacified. There is moderate mass effect resulting in left frontotemporal sulcal compression and mild compression of the left lateral ventricle. No significant midline shift.
