Foix - Alajouanine's syndrome

Overview also known as subacute necrotizing myelitis syndrome. Cause pathogenesis of vascular abnormalities due to spinal cord with necrosis. Vascular anomalies. To the main vein, was hunting-buckling, vascular stenosis inner wall thickening caused blood circulation problems that could lead to spinal cord lesions. After the clinical performance of adult morbidity, little children, the sex ratio is about 3 ~ 4:1. Double distal lower extremity muscle atrophy, early submissions spastic paraplegia and late submissions flaccid paralysis, tendon reflexes early hyperthyroidism, advanced disappear. Early onset was feeling separation barrier, as the illness progressed, the feeling after all disappeared. Early spinal often intermittent claudication. Differential diagnosis (1) incomplete spinal artery (spinal artery insufficiene y) before the onset of prodromal symptoms common to feel symptoms and movement symptoms. Symptoms sometimes feel pain, abnormal feeling sometimes, as a precursor to the pain symptoms were more common. Those in acute pain trunk or limbs, accompanied abnormal sensation such as numbness, acupuncture flu. The second is the precursor symptoms of movement disorders, suddenly appeared physically weak, such as sudden paraplegia, in a few minutes or a few hours to complete paraplegia, can be followed in a few minutes or a few hours to return to normal, often relapse in a short period of time. More seen in the emergence of spinal disease intermittent claudication. (2) spinal artery thrombosis (spinal arterial thrombosis) often precede with incomplete spinal artery attack, soon after spinal disease levy, often in a few minutes or 10 minutes have paralysis of limbs and lower limbs while two onset, or a limb down. Succeeding is another side of lower limbs were paralyzed. Spinal artery thrombosis performance gray matter lesions, there syringomyelia-sensory dysfunction. Caused a few cases of spinal cord hemi softening was Brown-Sequard syndrome. For the spinal artery collateral circulation rich, although there was little embolization clinical symptoms. (3) canal hemorrhage (bleeding intraspinal) extremely rare, major clinical symptoms of acute or chronic symptoms of spinal cord compression, rapid onset. (4) intramedullary tumor (intramedullary tumor) onset time of the two-leg damage symptoms, radicular pain rare feeling of early separation, muscular atrophy appeared earlier, the earliest sphincter barrier Nutrition disorders Obviously, the levy is a late Cone. Obstruction is a late canal, Dan White is not significantly increased.
