Did you mean: Early Upper Motor Neuron Signs, Hyperintensities in the Globus Pallidus (T2-Weighted, Pyramidal Tract Signs

  • Mitochondrial Membrane Protein-Associated Neurodegeneration

    tract signs with heavy iron accumulation at the globus pallidum and the substantia nigra [ 1 , 2 ].[omicsonline.org] Key Diagnostic Features: Once the parkinsonian symptoms appear, brain MRI shows hypointensity in the region of substantia nigra (SN) and globus pallidus (GP) on T2-weighted[ajnr.org] Early upper motor neuron signs (pyramidal signs, e.g. spasticity) are constant findings and are later followed by signs of lower motor neuron dysfunction (deep tendon reflex[malacards.org]

  • Hallervorden-Spatz Syndrome

    Table-1: Diagnostic features of Hallervorden spatz disease [11] Obligate Features Collaborate Features Exclusion Features Onset during first two decades Pyramidal tract signs[medresearch.in] This virtually pathognomonic radiographic abnormality, called the eye-of-the-tiger sign, comprises hyperintensities within a hypointense medial globus pallidus on T2-weighted[ncbi.nlm.nih.gov] […] pattern of hyperintensity within the hypointense medial globus pallidus.[ncbi.nlm.nih.gov]

  • Amyotrophic Lateral Sclerosis

    Autosomal dominant juvenile amyotrophic lateral sclerosis and distal hereditary motor neuronopathy with pyramidal tract signs: synonyms for the same disorder?[ncbi.nlm.nih.gov] Patients present with a pure upper motor neurone syndrome with either absent or minimal lower motor neurone signs.[doi.org] Signs of pyramid release are not always marked and, only recently, non-invasive tests to reveal cortical spinal tract commitment have been incorporated into the medical practice[doi.org]

  • Binswanger Disease

    The bilateral cerebral white matter and globus pallidus appeared hyperintense on T2-weighted imaging (Figures 5 and 6). 5) Figure 5. CO poisoning(FLAIR image) Figure 6.[plaza.umin.ac.jp] The hippocampus, cerebral white matter, basal ganglion, and other areas appear hyperintense on T2-weighted imaging. CO poisoning: Delayed diffuse demyelination.[plaza.umin.ac.jp] No contrast enhancement effect is evident.

  • Hemiplegia

    Sustained clonus is a sign of pyramidal Tract lesion. [6] Reflexes Reflexes are altered and also vary according to the stage of recovery.[physio-pedia.com] Classical Perspective-Spasticity/Hyperreflexia in Poststroke Hemiplegia The upper-motor neuron syndrome as described by John Hughlings Jackson involves a combination of negative[web.archive.org] signs-weakness and impaired dexterity or coordination-and positive signs-spasticity or hyperreflexia [26].[web.archive.org]

  • Central Pontine Myelinolysis

    In (CPM), the initial signs include dysarthria and dysphagia (secondary to corticobulbar fiber involvement), and flaccid quadriparesis (from pyramidal tract involvement) which[omicsonline.org] […] of Globus Pallidus (broad arrow), suggestive of Extrapontine myelinolysis.[ipfs.io] weighted magnetic resonance scan image showing bilaterally symmetrical hyperintensities in caudate nucleus (small, thin arrow), putamen (long arrow), with sparing of globus[en.wikipedia.org]

  • Cervical Spinal Cord Tumor

    Below that level, Upper Motor Neuron (UMN) findings are those of spasticity, hyperreflexia with upgoing Plantar reflex also called Babinski’s sign With Extradural lesion ([clinicaladvisor.com] […] i.e. spinal metastasis), early symptoms are motor and sensory in an asymmetric onset.[clinicaladvisor.com]

  • Multiple Sclerosis

    Subsequent symptoms also include more prominent upper motor neuron signs, i.e.,. increased spasticity, increasing para- or quardriparesis.[library.med.utah.edu] Early symptoms may include numbness and/or paresthesia, mono- or paraparesis, double vision, optic neuritis, ataxia, and bladder control problems.[library.med.utah.edu]

  • Subacute Transverse Myelitis

    Unequivocal upper motor neuron signs exclude AIDP, but are often not apparent in the early stages of a spinal cord insult.[neurology.org]
