Abstract:
OBJECTIVETo investigate the value of functional magnetic resonance imaging (MRI) in sequential evaluation of patients with Leigh syndrome.
METHODSTwo patients with Leigh syndrome underwent diffusion weighted imaging (DWI), perfusion weighted imaging (PWI) and proton magnetic resonance spectroscopy ((1)H-MRS).
RESULTSThe brain lesions showed hyperintensity on DWI, lactate doublet peak on MRS and hyperperfusion in the patients at baseline, and maintained a hyperintensity on DWI and hyperperfusion in the absence of lactate doublet peak on MRS at follow-up 1 year later. DWI still revealed persistent hyperintensity in the brain lesions in one patient 2 years later.
CONCLUSIONFunctional MRI can sensitively highlight the characteristics of brain lesions in patients with Leigh syndrome, and can therefore be used to evaluate the sequential changes of the brain lesions.
