Lhermitte's syndrome

Also known as outlined between former nuclear-ophthalmoplegia syndrome, the medial longitudinal fasciculus syndrome. Cause pathogenesis of the medial longitudinal fasciculus level Department of knee nerve damage caused. In view of multiple sclerosis and brain glioma Bridge, vascular disease, syphilis, alcoholism and inflammation of the brain stem patients. Clinical features of the unilateral nystagmus with the level gaze palsy. When attempting to eyeball horizontal lateral side deflection campaign, the monocular or two muscle paralysis there, the pool disappeared, Convergence function. Lateral rectus movement outside normal contralateral muscle weakness, normal pool. Horizontal nystagmus, in general both sides to follow when suddenly the outside than the inside nystagmus gone significantly. Eyeball to the top monitor, we can see the vertical nystagmus. Differential diagnosis (1) multiple sclerosis (multiple sclerosis) is a prime time The sheath from the central nervous system disease. Characterized by multiple lesions, and the symptoms of relapse and remission often turn up to the age of onset in 20 ~ 40 years old, 30-year-old for the summit. Subacute onset of many, as different parts of the lesion, the clinical signs, symptoms may be, God cranial damage sensory and motor function disorders. CSF protein, mainly IgG increased. CT and MTI can show early brain lesions. (2) Bridge brain tumors (tumor pons) represents half of the brain stem tumor above, with glioblastoma or mainly astrocytoma. Children diplopia, easy to slip as the first symptoms, adults with vertigo, with ataxia. Almost all patients had cranial nerve palsy symptoms, 50% of patients outside the abducens nerve palsy earliest. With tumor development, with the facial nerve, the trigeminal and other cranial nerve damage and limb God movement sensory dysfunction, cause cross-movement disorders. Skull X-ray, CT, MRI helps diagnosis. (3) intracranial aneurysms (intrac ranial aneurysm) 40 ~ 60-year-old multiple. Unruptured aneurysms may adjacent neurovascular compression caused symptoms, the main hazard is bleeding. Relying on the diagnosis of cerebral angiography, general demanded bilateral. Although the CT scan video aneurysm can be seen, but negative CT does not preclude the presence of aneurysms. (4) cerebral syphilis (syphilis brain) is close by the pale spiral violations leptomeningeal body and brain. persistent infection caused by substance. Clinically, it is manifested as syphilitic meningitis, meningovascular syphilis dementia and paralysis. CSF monocyte Increasingly, the protein content increased. Spiral serum and cerebrospinal fluid tests detect the antigen-positive. (5) brainstem encephalitis (brain stem encephalitis) mostly young adults, disease, before the virus infection. Sharp onset, often early psychiatric symptoms and disturbance of consciousness, rapid emergence of bilateral cranial nerve palsy, accompanied by one or both sides of the motor and sensory dysfunction, symptoms and signs rarely restricted to a particular location. After about seven-eight weeks of treatment 80% of patients improved.
