(A) and (B) Axial T1 contrast-enhanced sequence with evidence of nodular thickening of the optic chiasm (white arrow on A) and left optic tract (white arrow on B) associated with enhancement of these structures. (C) Sagittal T1 sequence demonstrating evidence of nodular thickening of the optical chiasm (white arrow). (D) Axial FLAIR sequence with hyperintensity of the temporal lobe's mesial region (red arrow) and the midbrain's left lateral margin (red arrow head). (E) and (F) Axial ADC, and DWI sequences show no evidence of restriction of the previously described structures.
