Tumor with surrounding FCD in an 18-year-old woman. Tumor with surrounding FCD in an 18-year-old woman. A, FLAIR sequence shows hyperintensity of the left amygdala and temporal lobe. B, FDG-PET/MR imaging coregistration demonstrates an area of hypometabolism extending beyond the lesion seen with MR imaging. After surgical resection, ganglioglioma was seen on pathology of the lesion (white arrow). Pathology of the area of hypometabolism surrounding the lesion (yellow arrow) showed histology consistent with FCD type I. K.K. Lee, and N.
