57 Possible Causes for 'Eye of the Tiger' Sign on MRI

  • Hallervorden-Spatz Syndrome

    Iron deposition in conjunction with destruction of the globus pallidus gives rise to the characteristic eye-of-the-tiger sign in MRI.[ncbi.nlm.nih.gov] […] of the tiger" sign.[ncbi.nlm.nih.gov] It has been postulated that pantothenate kinase 2 mutations underlying all cases of classic Hallervorden-Spatz syndrome are always associated with the eye-of-the-tiger sign[ncbi.nlm.nih.gov]

  • Neurodegeneration with Brain Iron Accumulation

    Individuals with PKAN and HARP syndrome, which is considered part of the PKAN disease spectrum, show a characteristic "eye of the tiger''sign on MRI, a central region of hyperintensity[orpha.net] sign in cranial MRI, this case most likely represented an idiopathic form of NBIA but atypical PKAN may be also considered.[ncbi.nlm.nih.gov] For all of the disorders in this category, T 2 -weighted brain MRI would distinguish PKAN based on the presence of the "eye of the tiger" sign.[ncbi.nlm.nih.gov]

  • X-linked Parkinsonism-Spasticity Syndrome

    T2-weighted fast spin echo (G) and T1-weighted (H) brain MRI scans from a child with PKAN demonstrating the "eye of the tiger" sign (courtesy of Susan J.[ojrd.biomedcentral.com] T2 weighted brain MRI shows an ”eye of the tigersign corresponding to pallidal hypointensity with a high signal center.[neuroweb.us] Onset can be later, with more rigidity in atypical forms of PKAN [ 12 ], but the typical MRI findings of the "eye of the tiger" sign suggest the diagnosis.[ojrd.biomedcentral.com]
