1,918 Possible Causes for 'Eye of the Tiger' Sign on MRI, Hyperreflexia, Increased Urinary Dopamine and Dopamine Metabolites (Paradoxical)

Did you mean: 'Eye of the Tiger' Sign on MRI, Hyperreflexia, Increased Urinary Dopamine and Dopamine Metabolites (Paradoxical

  • Aromatic L-Amino Acid Decarboxylase Deficiency

    […] of the tigersign on MRI.[] Of those patients who present at the average age with the typical dystonic gait disorder, 20% also have hyperreflexia and apparent extensor plantar responses, as well as other[] Association of autonomic nervous hyperreflexia and systemic inflammation in patients with Crohn's disease and ulcerative colitis.[]

  • 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.[] Neurologically, opisthotonus, rigidity of extremities, dystonia, hyperreflexia, profound emaciation, and bilaterally positive Babinski signs were present.[] Each patient had spastic gait, dysarthria, dystonic posturing of both arms and generalized hyperreflexia, but no Kayser-Fleischer rings or retinitis pigmentosa.[]

  • Mitochondrial Membrane Protein-Associated Neurodegeneration

    Most patients have progressive involvement of the corticospinal tract, with spasticity, hyperreflexia, and extensor plantar responses.[] None of our pa-tients exhibited the eye of the tiger sign on T2-weighted MRI.[] This is followed by the development of spastic quadriparesis and hyperreflexia and ultimately areflexia and a vegetative state by the end of the first decade.[]

  • Huntington Disease-Like 2

    Neurological abnormalities could include parkinsonism ( rigidity , bradykinesia , tremor ), dysarthria , and hyperreflexia .[] PKAN is associated with the pathognomonic ‘eye-of-the-tigersign, characterised by a central region of hyperintensity surrounded by a rim of hypointensity on coronal or axial[] […] ideation Dementia Relentless progression of disease with death 15-20 years after onset Successive generations tend to have earlier onset Juvenile onset symptoms Clumsiness Hyperreflexia[]

  • Degenerative Disorder

    […] of the tigersign on MRI brains scan and PANK2 mutations; secondly, a group of clinically atypical cases which did not have PANK2 mutations nor the “eye of the tiger sign[] ” but did have hypodensity in the globus pallidus on T2 weighted MRI brain scans, cerebellar atrophy, and often evidence of iron deposition in the red nucleus and dentate[] Hallervorden-Spatz syndrome 13 ) or atypical features with acanthocytosis, hypoprebetalipoproteinaemia and/or orofacial dyskinesia (known as HARP syndrome 14– 16 ) but all with the “eye[]

  • Adult-Onset Autosomal Recessive Cerebellar Ataxia

    : Clinical features Age of onset - 43-56 years Slow progression Gait and limb ataxia Dysarthria Occular dysmetria Slow saccades Decreased vibratory sense below the knees Hyperreflexia[] T2 weighted brain MRI shows an ”eye of the tigersign corresponding to pallidal hypointensity with a high signal center.[] […] and decreased ankle reflexes); movement disorders such as chorea, dystonia, and oculomotor abnormalities; pyramidal tract dysfunction such as extensor plantar responses, hyperreflexia[]

  • Canavan Disease

    Clinical manifestation is being noted for diagnosing such as presentation of joint stiffness and hyperreflexia including as well the presence of optic atrophy.[] A brain MRI at four years of age showed low-signal intensity rings surrounding central hyperintense T2-weighted signal in bilateral globus pallidi, (“eye of the tigersign[] After that, hypotonia progresses to spasticity, hyperreflexia, extensor plantar responses, and tonic extensor spasms. The extensor spasms may occur in response to noise.[]

  • Neuroferritinopathy

    Individuals with neuroferritinopathy also show the 'eye of the tiger'' sign.[] Disinhibition 0000734 Dysarthria Difficulty articulating speech 0001260 Dyskinesia Disorder of involuntary muscle movements 0100660 Emotional lability Emotional instability 0000712 Hyperreflexia[] Children with PKAN typically manifest gait problems around age 3 and later develop progressive dystonia, dysarthria, rigidity, spasticity, hyperreflexia and extensor toe signs[]

  • Infantile Neuroaxonal Dystrophy

    The MRI usually shows an area of hyperintensity in the medial globus pallidus that has been called the ‘eye of the tigersign but this is not pathognomonic.[] […] weakness 0003324 Gliosis 0002171 Global developmental delay 0001263 Hearing impairment Deafness Hearing defect [ more ] 0000365 Hyperactivity More active than typical 0000752 Hyperreflexia[] On physical examination there was optic atrophy, hypertonia and hyperreflexia.[]

  • Hyperventilation

    Loss of consciousness occurs in post-hyperventilation apnea, but its pathophysiology remains unclear. We herein report a patient with post-hyperventilation apnea showing spindle activity on electroencephalogram (EEG). The patient was alert and breathing spontaneously before the hyperventilation test, but loss of[…][]
