"MR spectroscopy"
"Although infrequently reported, MR spectroscopy findings include a decreased NAA/choline ratio and a characteristic abnormal peak at 3.8 ppm 5. This peak is thought to represent resonance of fucose-containing macromolecules such as oligosaccharides and glycolipids 5."

"MR spectroscopy"
"In the white matter, there is evidence of hypomyelination, with extensive, confluent, progressive, and symmetric signal anomaly in the periventricular and subcortical white matter 3-5,7. This white matter signal anomaly manifests as hyperintense on T2/FLAIR sequences, while T1 sequences are often unremarkable 3-5,7."
