Scattered punctate foci of susceptibility artifact within the cerebellar hemispheres and throughout the temporal poles. No abnormal parenchymal diffusion restriction or contrast enhancement.
Prior bilateral maxillary antrostomies and generalised mucosal thickening.
Conclusion:
Extensive tiny punctate foci of susceptibility artifact within the cerebellar hemispheres and throughout the temporal lobes are suggestive of prior radiotherapy, presumably for nasopharyngeal carcinoma.
