Temporal lobe radionecrosis

Case contributed by Assoc Prof Frank Gaillard


Previous nasopharyngeal carcinoma with radiotherapy.


The right temporal lobe demonstrates increased T2 signal predominantly in the white matter with minimal enhancement. MRS demonstrates preserved choline / NAA but an increase in lipid / lactate peaks.

Case Discussion

The imaging features of radionecrosis are variable and depend both on timing, dose and individual patients.
