Imaging findings of histologically confirmed recurrent high-grade glioma.

Fluid attenuated inversion recovery and T1weighted axial post contrast images showing a right-hand side temporal lesion with T2 prolongation and rim-enhancement in follow up imaging. The diffusion weighted image (b1000) and the corresponding apparent diffusion coefficent (ADC) map show slightly enhanced diffusion, represented by an increased ADC with T2shine through in the contrast enhancing portion of the lesion, suggestive for tumor recurrence.
