Hallervorden-Spatz Disease


MR- GRE images reveal marked symmetric decreased signal in the globus pallidi. Note that the signal disturbance is less pronounced on the fast spin echo T2 image; susceptibility artifacts of iron are less with FSE techniques.


Hallervorden-Spatz Disease (HSD) is also known as pantothenate kinase associated neurodegeneration and neurodegeneration with iron accumulation. HSD is caused by mutations in the pantothenate kinase 2 gene which is necessary for coenzyme A production in mitochondria. Deficiency of coenzyme A results in cysteine containing enzymes that can chelate iron. The markedly decreased signal that results from iron deposition in the globus pallidi gives rise to the classic “eyes of the tiger” appearance. Spectroscopy shows decreased NAA and elevated myo-inositol.
