An ovoid cystic lesion without enhancement, diffusion restriction or significant mass effect in the anterior left temporal lobe near the Sylvian cistern has a moderate rim of surrounding T2 FLAIR hyperintensity. Occasional punctate T2 FLAIR hyperintense focus in the supratentorial white matter within age-appropriate limits.
The lobulated irregular shaped delayed enhancing right pituitary lesion measuring up to 1.8cm encasing the right cavernous carotid artery with remodelling of the roof or with extension into the right sphenoid sinus is unchanged. The infundibulum is again slightly in shifted to the left. Normal cavernous carotid flow void preserved. Chiasm uninvolved.
Conclusion
Previously reported cystic left anterior temporal lesion measures smaller than the report from 8 years ago (not shown), but is larger than the report form 5 years ago (also not shown). It is characteristic of an anterior temporal lobe perivascular space.
Previously reported right pituitary adenoma invading cavernous sinus is stable compared scans from 5 years ago.
