Eye-of-the-Tiger sign is not Pathognomonic of Pantothenate Kinase-Associated Neurodegeneration in Adult Cases
An eye-of-the-tiger sign is previously known to have one-to-one correlation with pantothenate kinase-associated neurodegeneration (PKAN). Reviewing the literature on this subject, the correlation between eye-of-the-tiger sign and PKAN seems to show an interesting hypothesis that differs from conventional conclusion. We analyze the published papers in an attempt to reflect this trend and illustr...
متن کاملEye-of-the-tiger-sign in a 48year healthy adult
We report a healthy adult male, who underwent, as a control subject, part of a Huntington's disease study, extensive testing during three visits in a two year follow-up, including clinical examination and 3.0 T MRI scans. The T2-weighted MRI sequences revealed the "eye-of-the-tiger-sign". No clinical abnormalities in either motor, cognitive or behavioural domains were observed. PKAN2 and FTL ge...
متن کاملDiffusion tensor MR imaging in children with pantothenate kinase-associated neurodegeneration with brain iron accumulation and their siblings.
BACKGROUND AND PURPOSE It has been reported that iron concentration influences DTI metrics in deep gray matter nuclei. We hypothesized that increased FA in the deep gray nuclei may indicate abnormal iron accumulation in patients with PKAN and their siblings. MATERIALS AND METHODS Seven patients with the characteristic "eye-of-the-tiger sign," their 5 siblings, and 5 age-matched controls were ...

Fig. 1. (a) Patients with compound heterozygous PANK2 gene mutations and their family members. The blackened squares denote the number of patients. (b) ‘Eye of the tiger sign’ of patients PKAN-02, 03 and 04 in T2-magnetic resonance imaging (MRI) image. We identified six Chinese patients with sporadic PKAN, all of whom revealed the typical ‘eye of the tiger’ sign upon brain magnetic resonance im...
متن کاملPantothenate kinase 2 mutation with eye-of-the-tiger sign on magnetic resonance imaging in three siblings
BACKGROUND Pantothenate kinase associated neurodegeneration (PKAN) is the most prevalent type of neurodegeneration with brain iron accumulation (NBIA) disorders characterized by extrapyramidal signs, and 'eye-of-the-tiger' on T2 brain magnetic resonance imaging (MRI) characterized by hypointensity in globus pallidus and a hyperintensity in its core. All PKAN patients have homozygous or compound...
