Brown-Sequard syndrome

Overview also claimed that damage to the spinal cord hemi syndrome. Cause pathogenesis of spinal cord hemi disease, caused by trauma, spinal tumor, hemorrhage, Syringomyelia disease to spinal cord beam (Secretary of deep feeling and sensitivity), the lateral hypothalamus spinal beam (Secretary pain and temperature sense), spinocerebellar ataxia beam (Secretary proprioception), and Cone Beam side (Division Movement) damage. Clinical manifestations damaged parts of the contralateral pain, temperature Cox disappeared, on the side of the damaged plane following central paralysis and deep feeling of obstacles and ipsilateral spinal root symptoms (peripheral palsy, and sub-sections of spinal cord lesions of the skin corresponding regional perception disappear). Differential diagnosis (1) Brown-Sequard syndrome damage to the spinal cord exactly half of those extremely rare, not typical of many of Brown-Sequard syndrome, spinal cord lesions is not exactly half generally always more edge to another part of the hemi, the clinical manifestations vary leave. For example, half of spinal cord injury after hemi merged, the more edge to another hemineglect after Faso, in lesions on the limbs of a motor neuron lesions with paralysis below the level of bilateral conduction-beam deep feeling of identification inconsistent with obstacles Cox obstacles, pain and temperature sense can not obvious. This is not typical of Brown-Sequard syndrome and spinal cord do not need to complete the Trans-differential damage. Incomplete spinal cord disease transverse often in the early spinal shock, extremities or two lower limbs completely, flaccid paralysis, various reflexes disappear, the following lesions of all types of sensory dysfunction; With the lifting of spinal shock, Movement also obvious obstacles emerged, the extent of his paralysis and muscle tension increased as the extent of damage to complete the Trans-so obvious; Early appeared to be defensive reflex, two lower extremities spontaneous pain (both feet, thighs in front of the experienced unbearable pain). (2) extramedullary tumors (extramedullary tumor) Brown appeared in the early-s equard's syndrome for more oppression extramedullary lesion in tumors were the most common. Common early symptoms of radicular pain, the more rapid onset by side, there paresthesia or sensory dysfunction is a late, Cone levy appeared earlier that the general muscular atrophy, nutrition little obstacles, obstacles arise later sphincter. Obstruction canal early on and obviously, significantly higher protein, Froin's levy. If radicular pain suddenly appeared near paralysis often for hemangiomas and vascular malformations or cysts oppression. (3) incomplete spinal artery (spinal artery insufficiency) made for prodromal symptoms often before, the pain was mostly in the trunk or limbs, accompanied abnormal sensation, such as numbness, acupuncture flu, Link inductance, bound flu. The second is the precursor symptoms of movement disorders, such as sudden paralysis, can be followed in a few minutes or a few hours back to normal. More seen in the emergence of spinal disease intermittent claudication.
