Serial proton magnetic resonance spectroscopy (MRS), was carried out at 1-2 monthly intervals on eight patients with multiple sclerosis who presented with evidence of a large acute cerebral white matter lesion. An MRS was obtained from acute lesions (volumes of interest 4-12 ml), which at presentation showed gadolinium-diethylenetriamine penta-acetic acid enhancement, and from similar volumes of normal appearing white matter lateral to the lesion and nearer the scalp. Followup ranged from 4 to 9 months (mean 6 months). Short echo spectra from acute enhancing lesions invariably showed the presence of large resonances at 0.9 and 1.3 p.p.m. compared with normal appearing white matter and healthy age marched controls, indicating that these peaks were nor the result of voxel contamination from scalp fat. These resonances, which probably represent lipid products of myelin breakdown, were detected in lesions which had been enhancing for
