Double site of glioma infiltration in the right Rolandic frontal region: (A,B) Both lesions present similar hyperintensity on FLAIR images. The most cranial lesion (arrow) showed slight post-contrastographic enhancement (D) and restricted water diffusion on DWI (F), characterized by slightly low values on ADC map (H); this condition could be linked to an anaplastic aspect of the tumor, with restricted diffusion explained by an increase in tumor cellularity. The most caudal lesion did not show contrast enhancement, with a marked hypointense signal on post-contrastographic T1-weighted image (C); the same lesion presented no restricted diffusion with increased ADC values (E–G). FLAIR = fluid-attenuated inversion recovery; DWI = diffusion-weighted imaging; ADC: apparent diffusion coefficient.
