Abstract |
The majority of lipids in the brain are located in the bilayer membranes. These lipids are not visible by magnetic resonance spectroscopy since they have restricted mobility. Only mobile lipids, such as cholesterol esters or triglycerides in neutral lipid droplets, have enough rotational freedom to generate a signal on spectroscopy. These signals are detected as peaks at 1.3 ppm, originating from the methylene groups in the fatty acid chain, and 0.9 ppm, originating from the distal methyl group. We review the literature on the different genetic conditions that have been found to show lipid peaks on brain spectroscopy and report the first patient with carnitine palmitoyltransferase 2 deficiency shown to have such lipid peaks, thus indicating brain fat accumulation. |
