FA color map, SWI and single voxel proton MRS of trigeminal ganglioneuroma. a On the FA color map, the white matter fiber tracts surrounding the tumor appeared compressed and had shifted, but not damaged. A characteristic whorled appearance was showed in tumor. b Significant low signals suggesting bleeding or calcification were absence in the tumor on SWI. c Representative MRS imaging of tumor, left showed the MRS imaging, right showed the place of the voxel (square). d Representative MRS imaging of adjacent normal tissue, left showed the MRS imaging, right showed the voxel of adjacent normal tissue. Cho was not elevated and NAA peak was slightly reduced on proton MRS compare to adjacent normal tissues
