There is diffuse enlargement of brainstem, (midbrain, pons and more prominent in medulla oblongata), involving cervico-medullary junction, which appears hyperintense in T2W and FLAIR sequences, and shows no enhancement in T1W post contrast.
Also noted bilateral symmetrical hyperintense foci in both T2W and FLAIR sequences in basal ganglia, middle cerebellar peduncles, dentate nuclei, and show no contrast enhancement.
Diffuse brainstem enlargement and hyperintensity in T2W and FLAIR sequences, centered on medulla oblongata, involving the cervicomedullary junction, suggestive of brainstem glioma associated NF1.
Multiple focal areas of hyperintensity in basal ganglia, middle cerebellar peduncles, dentate nuclei, suggestive central nervous system manifestations of NF1.
