Eye of the Tiger: Looking Beyond Neurodegeneration with Brain Iron Accumulation Disorders

Abstract
The “eye-of-the-tiger” sign in brain magnetic resonance imaging (MRI) is typically associated with neurodegeneration with brain iron accumulation disorders, especially pantothenate kinase-associated neurodegeneration. However, very similar neuroimaging findings may be seen in other neurodegenerative disorders involving the basal ganglia. We report here a patient with fucosidosis who had MRI brain findings closely resembling the “eye-of-the-tiger” sign.
Note
The authors are grateful to the patient and his family, for their participation in this study. Molecular genetic testing of the patient was performed in MedGenome Labs Ltd., Bengaluru, India.
