Avllis's syndrome

Also known as outlined, spinal thalamic - suspected nuclear levy synthesis; Suspected nuclear-cord-thalamus paralysis syndrome. Cause pathogenesis of vascular, inflammatory or neoplastic lesions suspected violations of the nuclear and vagal nerve and spinal cord and thalamus. Lesions in the medulla or nearly jugular foramen Department. Clinical manifestations performance of the soft palate with ipsilateral vocal cord paralysis, loss of sensation in the throat, tongue after 1 / 3 of taste. Since his head following the contralateral side body pain, temperature Cox obstacles, proprioception normal. Sympathetic still obstacles, there Horner's levy. Differential diagnosis (1) vertebro - basilar artery insufficiency (vertebrobasilar ischemi a) vertebro - basilar artery system transient ischemic attack sometimes only performance of dizziness, vertigo, walk instability vague symptoms to be diagnosed. Focal if symptoms such as dizziness, diplopia, dysarthria, dysphagia, or bilateral cross-limb paralysis and sensory dysfunction, ataxia, and other more specific diagnosis is that the characteristics of its attack sudden onset and lasted for a short, the general unintentional obstacles, be repeated attack. Avellis syndrome associated with transient ischemic attacks suggest medullary involvement. (2) vertebro - basilar artery thrombosis (vertebrobasilar thrombosis) often prior to the onset of short-term, recurring vertebro - basilar artery insufficiency history of the event have a lasting focal neurological symptoms. clue vertebro - basilar artery thrombosis, the performance of vertigo, nystagmus, diplopia, and to heminopia, cortical blindness. Ophthalmoplegia, pronunciation unclear, dysphagia, limb ataxia, paralysis or cross-sensory dysfunction, quadriplegia. After accompanied occipital pain and varying degrees of disturbance of consciousness, was sometimes irrational and unconscious motivation or state of silence. (3) increased myelitis (ascending myelitis) majority in the spinal cord before the onset of a symptom ~ 2 weeks with fever, "cold" upper respiratory tract infection symptoms, with or without back pain, abdominal pain, constrictions flu symptoms of nerve root stimulation, and then suddenly limbs, weakness, numbness, loss and bowel and bladder dysfunction. From the lower extremity lesions started to develop very rapidly to complete paraplegia, and gradually affect the abdomen, chest, arm, neck and facial muscles, feeling associated with the level rising gradually, swallowing difficulties, speech problems and difficulty in breathing. (4) acute infectious Polyneuritis (acute infective polyneuriti s) called up palsy, a general characteristic of the peripheral neuritis, often quadriplegic, but bladder, rectal dysfunction little, in the event of speech, swallowing and breathing difficulty, suggesting cranial nerve involvement, a precarious condition. CSF protein-cell separation feature. (5) medullary tumors (tumor medulla oblongata) medullary tumors in the earliest disease - often vomiting, easily misdiagnosed as nervous and vomiting. With a different degree of headache, dizziness, and the emergence of earlier cranial nerve palsy symptoms, Early in the course of regular or irregular breathing, with the development of tumor suddenly stopped breathing. Increased intracranial pressure and palilledema not obvious. Many patients also accompanied by faster heart rate, sweating, intractable hiccups, and other symptoms.
