41 Possible Causes for Arnold Chiari Malformation, Lower Motor Neurone Lesion

  • Meningomyelocele

    Myelomeningocele in the sacral area can produce a lower motor neuron lesion, resulting in detrusor areflexia.[emedicine.medscape.com] [Article in English, Portuguese] Abstract Meningomyelocele is a malformation with high prevalence, and one of its main comorbidities is Arnold-Chiari malformation type II.[ncbi.nlm.nih.gov] This condition may be associated with the ARNOLD-CHIARI MALFORMATION and HYDROCEPHALUS.[connects.catalyst.harvard.edu]

  • Syringomyelia

    motor neuron lesion is found at the level of dysfunction; - look for atrophy and fasiculations of the hands and arms; - scoliosis: - scoliosis is associated with syringomyelia[wheelessonline.com] (Please consult our website information for Arnold-Chiari Malformation.)[neurosurgerydallas.com] Syringomyelia associated with Arnold Chiari malformation was documented in 49% (n 21) cases.[ncbi.nlm.nih.gov]

  • Spina Bifida

    Myelomeningocele in the sacral area can produce a lower motor neuron lesion, resulting in detrusor areflexia.[emedicine.medscape.com] We previously developed fetal lamb models to create and reverse lower extremity damage and the Arnold-Chiari malformation in utero.[ncbi.nlm.nih.gov] Design We previously developed fetal lamb models to create and reverse lower extremity damage and the arnold-chiari malformation in utero. we then applied our extensive experience[doi.org]

  • Cervical Spina Bifida without Hydrocephalus

    The paralysis in lumbosacral lesions is typically of the lower motor neuron type with flaccidity and diminished or absent tendon reflexes.[thamburaj.com] A complication of malformation of the shunt in children with myelomeningocele and Arnold-Chiari malformation.

  • Brain Stem Disorder

    […] face: Genuflected upper motor neuron fibers to ipsilateral facial nucleus On side opposite lesion • Impaired pain and thermal sense over half the body, sometimes face: Spinothalamic[slideshare.net] Type II is also known as "classic" Chiari malformation or Arnold-Chiari malformation.[webmd.com] (It is sometimes referred to as Arnold-Chiari malformation, recognizing the contributions of German pathologist Julius Arnold.)[weillcornellbrainandspine.org]

  • Paraparesis

    It may be caused by an upper motor neurone lesion in the spinal cord. Lower limb paraparesis may also be caused by an anterior cerebral artery stroke.[gpnotebook.co.uk] Chiari Malformation Syringomyelia Spastic paraparesis and small hand muscle wasting: Cervical myelopathy (C5-T1) Anterior horn cell disease (motor neuron disease) Syringomyelia[medicaleducationleeds.com] : Syringomyelia Anterior spinal artery infarction Spastic paraparesis and cerebellar signs: Demyelination (Multiple sclerosis) Friedreich’s ataxia Spinocerebellar ataxia Arnold[medicaleducationleeds.com]

  • Upper Limb Hypertrophy

    Many parts of the motor exam can help distinguish between upper motor neuron and lower motor neuron lesions (see Neuroanatomy through Clinical Cases Chapters 2 and 6).[neuroexam.com] MRI of the brain and spine (T1, T2, Proton PD sequences) revealed grade 1 Arnold Chiari malformation with long syrinx extending from cervico-medullary junction to T6 [FIGURE[neurologyindia.com] Interpretation Upper motor neurone lesions usually produce hyperreflexia. Lower motor neurone lesions usually produce a diminished or absent response.[patient.info]

  • Cervical Myelopathy

    When there is diagnostic ambiguity between the upper and lower motor neuron lesions in VAD, motor-evoked potential study can be helpful to diagnose peripheral neurological[ncbi.nlm.nih.gov] In general, lower motor neuron findings are seen at the level of the lesion, while upper motor neuron findings will be seen below the level of the lesion/cord compression[dynamicchiropractic.com] (i.e., hyporeflexia in the upper extremities and hyperreflexia in the lower extremities). 1 Another feature of CSM is that it will involve the axial skeleton and skip the[dynamicchiropractic.com]

  • Diastematomyelia

    The lumbar and thoracolumbar lesions in some patients could cause lower motor neuron findings in the legs and feet, such as decreased/absent reflexes, while thoracic lesions[nature.com] malformation and hydrocephalus, although in our series only one patient exhibited hydrocephalus secondary to an Arnold-Chiari deformity.[pubs.rsna.org] Other conditions, such as intramedullary tumors, tethered cord, dermoids, lipoma, syringomyelia, hydromyelia and Arnold-Chiari malformations have been described in medical[en.wikipedia.org]
